Athletics' Jake Diekman: Earns first win in relief
by RotoWire Staff | RotoWire

Diekman (1-6) earned the win against the Astros on Thursday after recording the final out of the eighth inning.

With two outs and a 6-6 tie in the eighth inning, Diekman stepped in for Blake Treinen to face Yordan Alvarez. The left-hander threw just two pitches to force Alvarez to ground out. Luckily, Matt Chapman homered in the bottom of the frame to hand the win over to Diekman and the A's. Through 56 appearances this season, the 32-year-old owns a 4.86 ERA and 1.40 WHIP.

Athletics' Jake Diekman: Dealt to A's
by RotoWire Staff | RotoWire

Diekman was traded from the Royals to the Athletics on Saturday, Jeff Passan of reports.

He was highly sought after in a market where late-inning arms are at a premium, and Oakland must have stepped up with a solid offer to get the Royals to move him with a few days remaining before the deadline. Diekman has a 3.36 FIP (4.75 ERA), 1.34 FIP and 63:23 K:BB in 41.2 innings. He slots in as the clear top left-handed reliever in Oakland's bullpen.

Royals' Jake Diekman: Takes loss in relief
by RotoWire Staff | RotoWire

Diekman (0-3) was charged with the loss against the Tigers on Wednesday after surrendering a run on a hit and a pair of walks over one inning. He struck out two.

The left-hander was asked to preserve a 2-2 tie when he entered in the eighth inning. Unfortunately, he quickly loaded up the bases with a leadoff walk, a double and another free pass, enabling Brandon Dixon to hit a sacrifice fly and score the winning run. Through 31 appearances, Diekman owns a 4.28 ERA, 1.17 WHIP and 41:16 K:BB.

Royals' Jake Diekman: Signs with Royals
by RotoWire Staff | RotoWire

Diekman signed a one-year, $2.25 million contract with the Royals on Wednesday, Jeffrey Flanagan of reports. The deal includes a mutual option for 2020.

Diekman opened the 2018 campaign with the Rangers, posting a 3.69 ERA and 11.1 K/9 across 39.0 innings before being dealt to the Diamondback prior to the trade deadline. The southpaw struggled with Arizona, but is a solid bounce-back candidate in 2019 given his overall body of work over the past three seasons (3.92 ERA and 10.6 K/9 across 117 innings). Diekman should fill a high-leverage role for the Royals.

Diamondbacks' Jake Diekman: Tosses scoreless inning
by RotoWire Staff | RotoWire

Diekman struck out two batters as part of a perfect seventh inning Sunday in the Diamondbacks' 2-0 loss to the Rockies.

Diekman had been charged with at least one run in all but one of his last six appearances out of the bullpen, so his perfect frame Sunday may have helped him regain some confidence heading into the season's final week. The lefty has been one of several key relievers for Arizona who have fallen on hard times in September, with his downturn in performance along with those of Brad Boxberger, Archie Bradley and Andrew Chafin proving damaging to the Diamondbacks' hopes for a playoff spot.

Diamondbacks' Jake Diekman: Credited with hold
by RotoWire Staff | RotoWire

Diekman gave up one run on one hit and a walk over an inning of relief Sunday in the Diamondbacks' 9-5 loss to the Braves.

The Diamondbacks held a 4-2 lead heading into the top of the eighth inning before the bullpen squandered that advantage. Diekman was the first reliever to cave, though he at least limited the damage to one run while working the eighth, allowing him to come away with his second hold as a member of the Diamondbacks. Closer Brad Boxberger then went on to blow the save in the ninth and take his third loss in four appearances, raising further questions about his security at the back of the bullpen. Even if manager Torey Lovullo opts to make a change at closer, it would likely be Yoshihisa Hirano that gets the first crack at the gig rather than Diekman.

Diamondbacks' Jake Diekman: Provides clean appearance
by RotoWire Staff | RotoWire

Diekman tossed a scoreless seventh inning Friday in a 9-4 win over the Padres.

Aside from a blowup against the Phillies on Aug. 7, Diekman has been as good as advertised since the Diamondbacks acquired him from the Rangers on July 31. The lefty has kept the opposition off the board in his other five appearances with the club and has retired five of the last six hitters he's faced via strikeout.

Diamondbacks' Jake Diekman: Traded to Arizona
by RotoWire Staff | RotoWire

Diekman was traded from the Rangers to the Diamondbacks on Tuesday in exchange for Wei-Chieh Huang and a player to be named later, Robert Murray of The Athletic reports.

There was a chance that if Diekman hadn't been traded, he would have competed for saves down the stretch in Texas, but that is now out the window. Brad Boxberger is the established closer in Arizona, and Archie Bradley and Yoshihisa Hirano are also likely ahead of Diekman on the depth chart. The hard-throwing lefty has a 3.69 ERA, 1.38 WHIP and 48:23 K:BB in 39 innings this season.

Rangers' Jake Diekman: Nabs second save despite homer
by RotoWire Staff | RotoWire

Diekman allowed a run on two hits but still picked up his second save Wednesday against Kansas City.

Diekman gave up a home run right away to Mike Moustakas, but managed to get out of the inning with the help of a caught stealing to end the game. Closer Keone Kela had recorded saves in consecutive games and three of the past four nights heading into Wednesday, and Kela should be expected to slide right back into the closer's role for Texas's next game Friday should the Rangers encounter another save situation.

Rangers' Jake Diekman: Picks up first win
by RotoWire Staff | RotoWire

Diekman (1-0) was credited with the win after he allowed a hit and struck out one over a scoreless inning Saturday against the Angels.

Jose Leclerc and Diekman threw blanks over the eighth and ninth innings, respectively, giving the Rangers' quiet bats an opportunity to scratch out two late runs and send the game into extra innings. They plated another run in the 10th to turn what was nearly a loss into a win. Diekman has a 2.08 ERA with 16 strikeouts over his last 13 innings.

Rangers' Jake Diekman: Returns to action
by RotoWire Staff | RotoWire

Diekman (elbow) returned to action Friday against the Red Sox, allowing one run in one inning.

Diekman was hit by a comebacker Tuesday against Cleveland and suffered a bruise on his elbow. The issue wasn't a major one though, as he was able to play in a game a mere three days later.

Rangers' Jake Diekman: Hit by comebacker Tuesday
by RotoWire Staff | RotoWire

Diekman suffered a bruise above his left elbow and on his back during Tuesday's game against the Indians, Jeff Wilson of the Fort Worth Star-Telegram reports.

Diekman came on in relief Tuesday and was struck by a comebacker off the bat of Edwin Encarnacion that left him with a couple of bruises. The lefty claims he'll be fine moving forward, but it's a situation worth monitoring as the bruise on his arm could potentially cause him some discomfort while throwing. Consider him day-to-day.

Rangers' Jake Diekman: Picks up save
by RotoWire Staff | RotoWire

Diekman pitched a scoreless inning, allowing one hit and striking out two as he recorded his first save of the season Sunday against the Astros.

Diekman had an opportunity to get the save after the Rangers deployed Keone Kela during a 1-1 game in the ninth inning. He's struggled through his first eight appearances (three earned runs over 5.0 innings), but he'll look to build off Sunday night's outing moving forward.

Rangers' Jake Diekman: Making case for closer job
by RotoWire Staff | RotoWire

Diekman has not allowed an earned run in three of four spring outings, Drew Davison of the Fort Worth Star-Telegram reports.

Diekman made quite a splash at the tail end of 2017 when he held opponents scoreless in 10 of his 11 outings, mostly in a setup role. If the left-hander continues to throw zeros, manager Jeff Banister could slot him in at closer. That would allow him to deploy Alex Claudio, the incumbent closer, in a multiple-inning bridge role, one in which Banister thinks he could be more valuable to the team. "There are opportunities for [Claudio] to come in any inning and help preserve a win for us," Banister said. The battle appears to come down to Claudio or Diekman, with Keone Kela (shoulder) also in the mix.

Rangers' Jake Diekman: Competing for closing gig
by RotoWire Staff | RotoWire

Diekman is set to compete with Alex Claudio and Keone Kela for the Rangers' closing gig during spring training, Evan Grant of The Dallas Morning News reports.

Diekman received some good news Saturday when free-agent pickup Seung Hwan Oh's agreement with the Rangers was nixed due to a failed physical, leaving three pitchers left to contend for the ninth-inning vacancy. Alex Claudio, who finished last season as closer while notching 11 saves in 15 opportunities, looks like the tentative frontrunner, though Diekman and Kela would offer harder-throwing options from the left and right side, respectively, if manager Jeff Banister wants more of a power pitcher at the back end. Diekman quickly established himself as a dependable setup arm for the Rangers upon making his season debut last September following an extended recovery from surgery to address ulcerative colitis. He turned in scoreless outings in 10 of his 11 appearances and collecting five holds and a save.

Rangers' Jake Diekman: Avoids arbitration
by RotoWire Staff | RotoWire

Diekman agreed to a one-year, $2,712,500 deal with the Rangers on Friday, Jeff Wilson of the Fort Worth Star-Telegram reports.

This was the final offseason as an arbitration-eligible player for Diekman. In 2017, the left-hander fought through three procedures to address ulcerative colitis, which only allowed him to pitch in 11 games toward the end of the year. Even so, Diekman provided a strong presence at the back of the bullpen, posting a 2.53 ERA and 1.31 WHIP in 10.2 innings, positioning himself for a potential breakthrough as a setup man in 2018.

Rangers' Jake Diekman: Picks up save Sunday
by RotoWire Staff | RotoWire

Diekman didn't allow a hit or run over 1.2 innings of a 4-2 win against the Angels on Sunday. He walked one and recorded the save.

This is the first save of the season for Diekman and fifth of his career. Apart from a two-hit, three-run hiccup in his last appearance against the visiting Mariners, Diekman has been solid in his other six outings since returning from the 60-day disabled list (no runs, no hits, eight strikeouts over 6.7 innings). Given his solid performance, look for the Rangers to continue to use the big southpaw in high-leverage situations for the remainder of the season.

Rangers' Jake Diekman: Registers second hold Saturday
by RotoWire Staff | RotoWire

Diekman tossed a scoreless seventh inning and struck out a batter in Saturday's 7-4 loss to the Angels in 10 innings.

Manager Jeff Banister has wasted no time working Diekman back into high-leverage duties out of the bullpen since the lefty was activated from the 60-day disabled list Friday after having been sidelined all season following three surgeries to address ulcerative colitis. Diekman has picked up holds in back-to-back contests with a pair of perfect innings, and could settle in as the primary setup man to closer Alex Claudio with Jose Leclerc and Ricardo Rodriguez having struggled in recent appearances.

Rangers' Jake Diekman: Officially activated
by RotoWire Staff | RotoWire

Diekman (abdomen) was activated from the 60-day disabled list Friday, Jeff Wilson of the Fort Worth Star-Telegram reports.

As expected, Diekman was reinstated with active MLB rosters expanding to 40 players Friday. The lefty showed no real ill effects while on his rehab assignment from the three separate surgeries he underwent earlier this year to repair and rebuild his colon, posting an 8:0 K:BB in 6.1 scoreless innings between Frisco and Round Rock. He should immediately step into a back-end role in the Texas bullpen.

Rangers' Jake Diekman: Scheduled to return from DL on Friday
by RotoWire Staff | RotoWire

Rangers manager Jeff Banister said that Diekman (abdomen) is expected to be activated from the 60-day disabled list Friday, Connor Mount of reports.

Diekman passed the final hurdle in his recovery from three surgeries within the past year to repair and rebuild his colon by making appearances in back-to-back games Monday and Tuesday for Double-A Frisco, marking the fifth and six appearances in total of his rehab assignment. The lefty has looked utterly dominant in those outings, giving up just one run over 6.1 innings while striking out eight batters and walking none. Given the dearth of quality relief options for the Rangers, Diekman will have a decent chance at settling into a key setup role right away upon returning from the DL. He accrued a 3.40 ERA and 59:26 K:BB across 53 innings with the Rangers in 2016.
