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.

Diamondbacks' Drey Jameson: Logs two scoreless innings
Rotowire
Jameson allowed a hit and a walk over two scoreless innings in Saturday's spring game against Oakland.
Jameson and Ryne Nelson, the two leading candidates for Arizona's fifth-starter job, started split-squad contests Saturday. After round one, Jameson has the edge, as Nelson was knocked around by the Rockies for four runs in one-plus innings.

Diamondbacks' Drey Jameson: Starting in split squad matchup
Rotowire
Jameson will start on the mound for Arizona in Saturday's split-squad game against Oakland, Theo Mackie of The Arizona Republic reports.
Jameson turned a few heads in his brief major-league stint last season, posting a 1.48 ERA and 1.11 WHIP through 24.1 frames in four starts. He's one of the primary candidates for the fifth spot in Arizona's rotation alongside Ryne Nelson, who will start in the D-backs' other split-squad matchup Saturday against Colorado.

Diamondbacks' Drey Jameson: Will battle for rotation
Rotowire
Jameson is expected to compete for the No. 5 starter job this spring, Nick Piecoro of the Arizona Republic reports.
Jameson started 2022 at Double-A Amarillo before moving on to Triple-A Reno, and he was effective in a four-start stint with the Diamondbacks. The 25-year-old right-hander pitched to 1.48 ERA over 24.1 innings and threw at least six innings in three of his four starts while up in the majors. He and Ryne Nelson are considered the top candidates for the rotation, ahead of Tommy Henry and Brandon Pfaadt.

Diamondbacks' Drey Jameson: Records third win
Rotowire
Jameson (3-0) earned the win Saturday, allowing two runs on six hits and two walks over six innings against the Giants. He struck out seven.
Jameson's biggest mistake came on a solo home run from third baseman J.D. Davis with two outs in the sixth inning to cut Arizona's lead to 3-2. This was just the fourth major-league start of the 25-year-old's career, and he has allowed two runs or fewer in all four with three of them being quality starts.

Diamondbacks' Drey Jameson: Fans seven in second win
Rotowire
Jameson (2-0) picked up the win in the second game of Tuesday's doubleheader split with the Dodgers, allowing two runs on seven hits and a walk over six innings. He struck out seven.
After tossing seven shutout innings in his big-league debut last Thursday, Jameson delivered another quality start for Arizona in his encore. The 25-year-old righty tossed 62 of 94 pitches for strikes and extended his career-opening scoreless streak to 12.1 frames before Max Muncy touched him up for a two-run blast. Jameson had some issues keeping the ball in the park in the minors, but with two impressive outings out of the gate, he seems to be locking down a spot in the D-backs' Opening Day rotation in 2023.

Diamondbacks' Drey Jameson: Receives another start
Rotowire
Jameson is scheduled to start Tuesday in the second game of a doubleheader with the Dodgers in Los Angeles.
The rookie right-hander is unsurprisingly getting a second turn through the rotation after he struck out five while holding the Padres scoreless over seven frames in his MLB debut last week. Prior to his call-up from Triple-A Reno, Jameson posted unremarkable numbers (6.95 ERA, 1.59 WHIP) over a larger sample of innings (114) in the hitter-friendly Pacific Coast League, so he won't make for the most comfortable streaming option in a road start against one of baseball's top offenses.

Diamondbacks' Drey Jameson: Dazzles in big-league debut
Rotowire
Jameson (1-0) earned the win over San Diego on Thursday, allowing two hits and one walk while striking out five batters over seven scoreless innings.
Jameson has posted an uninspiring 6.95 ERA and 1.95 WHIP in 22 outings at the Triple-A level this season, but he looked like a seasoned major-leaguer in his Diamondbacks debut. The 25-year-old surrendered just two hits in the contest, keeping the Padres off the scoreboard for seven frames. Jameson wasn't overpowering -- he induced a modest eight swinging strikes -- but he allowed just two runners to reach second base and retired the final nine batters he faced. Given his strong start Thursday, he's likely to get another turn in the rotation next week.

Diamondbacks' Drey Jameson: Promoted for MLB debut
Rotowire
Jameson was called up from Triple-A Reno and will start Thursday against the Padres.
The 25-year-old was previously announced as the starter for Thursday's series opener, and he's now officially been added to the big-league roster. Jameson has a 6.95 ERA, 1.59 WHIP and 109:42 K:BB across 114 innings with Reno this year, and he'll have a tough matchup versus the Friars in his MLB debut.

Diamondbacks' Drey Jameson: Making MLB debut Thursday
Rotowire
The Diamondbacks will promote Jameson from Triple-A Reno to start Thursday's game against the Dodgers, Nick Piecoro of The Arizona Republic reports.
The 25-year-old right-hander becomes the latest upper-level pitching prospect to get a trial in the big-league rotation after Tommy Henry and Ryne Nelson both received looks in the second half of the season. Henry has since been moved back to Reno, but Jameson will now receive a look as Arizona temporarily expands to a six-man rotation in a busy portion of the schedule. Though Jameson's numbers at Reno aren't impressive on the surface (6.95 ERA, 1.95 WHIP and 109:42 K:BB over 114 innings), he pitched primarily in hitter-friendly parks in the Pacific Coast League. He's at least done well to keep the free passes in check since the All-Star break (6.4 percent walk rate in 54.1 innings).

Diamondbacks' Drey Jameson: Struggling since promotion
Rotowire
Jameson has struggled to the tune of an 11.05 ERA, 2.25 WHIP and 11:14 K:BB through four starts since being promoted to Triple-A Reno.
That's certainly a far cry from the 2.41 ERA and 0.93 WHIP he put up across four Double-A outings before getting promoted. It's hard to find positives in any of his outings for Reno thus far; in the best one, May 19 against Las Vegas, he at least managed to last into the sixth inning, though he still gave up four runs and struck out just four with three walks. This will certainly slow his progression to the big leagues, but it's worth noting that Jameson has great stuff and adjusted brilliantly after being blown up in his first Double-A start of the season. He's likely to get right as he adapts to the higher level of competition in Triple-A.

Diamondbacks' Drey Jameson: Elevated to Triple-A
Rotowire
The Diamondbacks promoted Jameson from Double-A Amarillo to Triple-A Reno on Thursday, Zach Buchanan of The Athletic reports.
Jameson quickly course corrected after a rough season debut April 8 against Midland, as he permitted just one run while striking out 20 over his last 17 innings spanning three starts. The string of strong outings will allow Jameson to move up a rung on the minor-league ladder to put him on the doorstep for his MLB debut. The 8-11 Diamondbacks likely don't fancy themselves as contenders, and that fact coupled with Jameson's status as a non-40-man roster player means that he may have to dominate at Reno to earn a call-up to the majors in the second half of the 2022 campaign.

Diamondbacks' Drey Jameson: Dominating at Double-A
Rotowire
Jamison has a 1.98 ERA, 0.85 WHIP and 41:6 K:BB in 27.1 innings since his promotion to Double-A Amarillo.
He's tossed seven-plus innings in three straight starts and has recorded double-digit whiffs three times in his four Double-A outings. Jameson wasn't quite this good at High-A Hillsboro, where he put up a 3.92 ERA and 1.22 WHIP, but those stats obscure the fact that he put up a 1.69 ERA and 0.99 WHIP in his last six outings for Hillsboro before being promoted. The 23-year-old righty out of Ball State was a first-round pick in 2019, and he's suddenly not too far from the majors. He almost certainly won't come up this year, but a promotion in the middle of next season is quite possible if he keeps pitching this well.
