Jameson allowed five hits and one walk while striking out six over 3.2 relief innings to earn a hold in Monday's 7-5 win over Colorado.
Starter Ryne Nelson put the Diamondbacks in an early 4-0 hole, but Arizona's bats and Jameson's multi-inning relief effort bailed him out. Jameson made his first appearance since being recalled from Triple-A Reno and figures to work as a multi-inning reliever, who can spot start if need be. He started three games for Arizona earlier this season but was optioned to the minors following a disastrous one-inning outing against the Padres. The right-hander had lost the ability to command his slider and became too predictable, leaning too heavily on his fastball, per Nick Piecoro of the Arizona Republic. He rediscovered the slider in the minors, and it was the pitch he used the most often Monday (28 times among 59 pitches).

Diamondbacks' Drey Jameson: Bullpen role expected
Rotowire
Jameson will throw out of the bullpen for Arizona, Steve Gilbert of MLB.com reports. The right-hander was called up Saturday when the Diamondbacks sent Brandon Pfaadt to the minors.
A rotation shakeup loomed as Zach Davies was activated from the injured list to start Saturday. That transaction coupled with the Pfaadt demotion signaled an easy one-to-one-swap of Davies and Pfaadt. However, things got murky during Saturday's game when manager Torey Lovullo brought starter Tommy Henry in as a reliever, which led to speculation about Jameson entering the rotation and Henry going to the bullpen. Lovullo cleared up matters following the game, noting that the left-handed Henry will remain in the rotation and pitch Wednesday -- he faced four batters and threw just 10 pitches. Jameson is expected to serve in a multi-inning relief role.

Diamondbacks' Drey Jameson: Back in big leagues
Rotowire
Jameson was recalled from Triple-A Reno on Saturday.
Jameson made three starts and three relief appearances early in the season, winning two games and saving another, but he was optioned in late April despite recording a 3.71 ERA. His 16.0 percent walk rate was high, and while he cut that mark down to 8.9 percent across five Triple-A starts, he also posted a 5.79 ERA. His promotion Saturday comes in the same set of transactions as Brandon Pfaadt's demotion but also Zach Davies' return from the injured list, so Jameson may have to settle for a relief role for now.

Diamondbacks' Drey Jameson: Optioned to Triple-A
Rotowire
Jameson was optioned to Triple-A Reno on Monday.
He'll cede his spot on the 26-man active roster to Tommy Henry, who who was called up from Triple-A in advance of his start Monday against the Royals. Jameson has labored in his last two starts, lasting just one inning in his most recent outing Sunday. He should join Reno's rotation to work on his efficiency. Though Henry is filling Jameson's spot in the rotation for now, prospect Brandon Pfaadt could eventually occupy the spot if Henry falters in his return to the big leagues.

Diamondbacks' Drey Jameson: Yanked after one inning
Rotowire
Jameson (2-1) allowed three runs on three hits and three walks in one inning Sunday, striking out one and taking a loss against the Padres.
Jameson needed 43 pitches to get through a disastrous first inning and didn't even get the opportunity to go back out. The Padres batted around the lineup, and most of the damage came on Matt Carpenter's two-run double. Prior to Sunday's outing, Jameson had allowed just four runs through 16 innings this season. He saw his ERA jump from 2.25 to 3.71 alongside a 16:12 K:BB. Jameson's next outing is currently scheduled to be in Colorado.

Diamondbacks' Drey Jameson: Solid in second start
Rotowire
Jameson did not factor into the decision Tuesday against the Cardinals, allowing two runs on four hits and four walks over 3.2 innings. He struck out three.
Jameson continues to provide valuable innings on the mound for Arizona. The 25-year-old has acquired two impressive wins and a save on the season, posting a 2.25 ERA and 1.25 WHIP over 16 innings between the rotation and bullpen. While he did not factor into this decision, Jameson limited the Cardinals' batters to two runs on four hits before being relieved in the fourth inning. He figures to get another start in the upcoming series with San Diego while Zach Davies (oblique) remains sidelined.

Diamondbacks' Drey Jameson: Sleeper pitchers for Week 4 (April 17-23)
Rotowire
Drey Jameson's return to the starting rotation went without a hitch, other than him lasting only four innings, but he'll be better equipped to take on more in his second and third outings. Those will come against the Cardinals and Padres, neither of which makes for a favorable matchup, but Jameson has the upside to make good anyway.

Diamondbacks' Drey Jameson: May get multiple starts
Rotowire
Jameson may make multiple starts as a fill-in for Zach Davies, whose oblique strain is expected to take "several weeks" to heal, Nick Piecoro of The Arizona Republic reports.
Arizona manager Torey Lovullo described Davies' injury as "more than a (Grade) 1," with a Grade 1 strain being the least severe. Jameson excelled in his first start as a replacement for Davies, shutting down the Brewers over four scoreless innings last Wednesday. His next expected start is Tuesday in St. Louis. Jameson pitched as a starter in spring training -- he eventually lost out on the No. 5 job to Ryne Nelson -- and should be able to build up higher pitch counts and get deeper into games.

Diamondbacks' Drey Jameson: Stellar in spot start
Rotowire
Jameson did not factor into the decision Wednesday, tossing four scoreless innings on three hits and zero walks during a 7-3 win over Milwaukee. He struck out four.
Jameson was filling in for Zach Davies, who was recently placed on the 15-day injured list with an oblique injury, and despite looking sharp through four innings, he was pulled after just 54 pitches. The second-year right-hander would seem to be an intriguing streaming option while Davies is out, especially as he stretches out further after a brief stint in the bullpen. He's tentatively scheduled to pitch again versus St. Louis next week.

Diamondbacks' Drey Jameson: Starting Wednesday vs. Brewers
Rotowire
Jameson will start Wednesday against the Brewers, Jody Jackson of Bally Sports Arizona reports.
Jameson is moving into the rotation to replace Zach Davies after Davies was placed on the 15-day injured list with his oblique strain. The right-hander has registered a 2.16 ERA and whiffed eight hitters in his 8.1 innings of work. There are some talented arms in the Arizona system who could replace Jameson if he struggles early -- namely top prospect Brandon Pfaadt -- but it seems likely that he'll be given a few turns in the rotation to begin the year.

Diamondbacks' Drey Jameson: Possible waiver wire pickups
Rotowire
It didn't seem like Zach Davies would be long for the Diamondbacks rotation with some of the young arms they had waiting in the wings, but a strained oblique has already taken the drama out of it. Drey Jameson, who has been kept warm in long relief, will get the first crack at the job. He has a fastball that pushes triple digits but was leaning all the more on his slider out of the bullpen, delivering some impressive whiff rates. There are some warts, such as shaky control and an inconsistent minor-league track record, but the upside is enough to roll the dice on him.

Diamondbacks' Drey Jameson: Moving into rotation
Rotowire
Diamondbacks manager Torey Lovullo announced Sunday that Jameson is moving into the starting rotation while Zach Davies (oblique) is on the injured list, Theo Mackie of The Arizona Republic reports.
Jameson has been effective out of the bullpen for the Diamondbacks thus far with a 2.16 ERA and 8:5 K:BB over 8.1 innings in three appearances. The right-hander has worked at least two innings in each of his outings -- including four against the Dodgers on March 31 -- and he should be stretched out after competing for the fifth starter spot in the Cactus League. If Jameson pitches well over his first few outings he has a good chance to stay in the rotation even after Davies is ready to return. If the 25-year-old were to struggle, the Diamondbacks could turn to top prospect Brandon Pfaadt in the coming weeks.

Diamondbacks' Drey Jameson: Thriving in bullpen
Rotowire
Jameson (2-0) allowed one walk while striking out one over 2.1 scoreless relief innings to pick up the win in Friday's 6-3 victory over the Dodgers.
Jameson, who lost out on the fifth starter job in spring training, has thrived as a reliever. In three appearances, the right-hander has earned two wins and save while never pitching fewer than two innings. Arizona manager Torey Lovullo appears to have made a shrewd decision in moving him to the 'pen in a multi-inning role instead of having him start in the minors. The dark lining to this silver cloud are the two home runs and five walks allowed along with a .158 BABIP, which project a 6.23 FIP. Fortunately for Jameson, both homers were solo shots and the free passes have not hurt.

Diamondbacks' Drey Jameson: Earns two-inning save
Rotowire
Jameson picked up the save Tuesday against San Diego. He allowed one run on three hits and one walk while striking out two over two innings.
He lost the battle for the final rotation spot to Ryne Nelson, but Jameson is having a great opening week regardless as he grabbed his first win of 2023 on Friday and now has his first career save to go with it. The back end of the Arizona bullpen has been shaky early on and Jameson, a top 10 prospect in the organization, could quickly emerge as a go-to option in high leverage. He could also stretch back out into a starter's role at some point.

Diamondbacks' Drey Jameson: Notches win in relief
Rotowire
Jameson (1-0) picked up the win in Friday's 2-1 victory over the Dodgers, allowing one run on two hits and three walks over four innings of relief. He struck out five.
Merrill Kelly got the start but lasted only 3.2 innings and 74 pitches, forcing the Diamondbacks to turn to their bullpen early. Jameson stepped up with an impressive performance in long relief, firing 38 of his 66 pitches for strikes with 13 swinging strikes. The 25-year-old will continue in his bullpen role for now, but if a spot opens up in the rotation, expect him to get first crack at filling it.

Diamondbacks' Drey Jameson: Opening season in bullpen
Rotowire
Jameson will begin the 2023 campaign working out of the bullpen after Ryne Nelson was named Arizona's No. 5 starter Sunday, Nick Piecoro of The Arizona Republic reports.
Neither pitcher performed particularly well during spring training with ERAs above 7.00, but it'll be Nelson that receives the first crack at the rotation in 2023. Jameson was lights out in his first taste of the majors last year with a 1.48 ERA and 24:7 K:BB across 24.1 innings (four starts).

Diamondbacks' Drey Jameson: Fans seven Thursday
Rotowire
Jameson allowed four runs on four hits and four walks while striking out seven over 4.1 innings in Thursday's split-squad start against the Dodgers.
Jameson gave up three runs in the first inning, then got a ton of run support -- 10, in fact -- during the bottom half of the inning. He settled in after that, although he dealt with base runners in four of the five innings he worked. Jameson's competition for the No. 5 starter job, Ryne Nelson, pitched in the other split-squad game and allowed three runs on four hits and two walks over 4.2 innings against the Cubs. Neither pitcher has a statistical advantage in the job battle, which looks like it will go down to the wire.

Diamondbacks' Drey Jameson: Rainouts force schedule change
Rotowire
Jameson threw in a minor-league game Friday, Nick Piecoro of the Arizona Republic reports.
Jameson was one of several pitchers affected by the two-game rainout Wednesday and was adjusted to throw Friday. Arizona manager Torey Lovullo said Jameson showed excellent velocity on his fastball, which touched triple digits. The manager also said nothing should be read into the fact that he didn't pitch in a Cactus League game. Jameson is one of four starters still competing for the final spot in the rotation.

Diamondbacks' Drey Jameson: Works three-plus innings
Rotowire
Jameson allowed five runs on seven hits and one walk while striking out four over three-plus innings in Sunday's spring start against the Rockies.
Jameson allowed a pair of home runs in his fourth Cactus League start. The right-hander got off to a good start this spring in his quest to claim the No. 5 starter job, but he's been knocked around his last two times out with eight runs and 11 hits allowed over the last 5.2 innings. Jameson's main competition for the job, Ryne Nelson, appeared as a reliever Sunday and fared better (one run, four hits, 2.2 IP).

Diamondbacks' Drey Jameson: Embraces changeup
Rotowire
Jameson pitched better during his start Monday after going to his changeup, Steve Stockmar of MLB.com reports. "Early on in games, I don't want to use it if I don't have to," he said. "I probably should have gone to it a lot earlier than I did."
Jameson was worked over by the Royals in the first couple of innings Monday before manager Torey Lovullo removed him from the game with two outs in the second frame. The manager brought Jameson back in for the third inning, and the right-hander was dialed in with the help of his changeup. Lovullo believes Jameson was sharp but made mistakes on 0-2 pitches that hurt. Jameson pitched well in his first two Cactus League starts and is considered the frontrunner for the final rotation spot.
