Detmers probably won't be moving into the Angels' rotation despite the demotion of Jack Kochanowicz to the minors, per Aaron Coloma of SI.com.

EDGE Analysis

Kochanowicz and Detmers battled for the fifth starter role in spring training, with the former ultimately getting the role. However, Kochanowicz has struggled to a 6.03 ERA over 19 starts and was sent down to Triple-A Salt Lake on Friday. When asked ahead of that demotion whether Detmers could be an option to move from the bullpen into a starting role, interim manager Ray Montgomery stated, "I would hate to say no to anything, but I don't think that's going to happen." Detmers has thrived in a setup role -- though he has posted a mediocre 4.15 ERA on the campaign, that is largely due to a horrific three-outing stretch in late April and early May during which he allowed 12 runs over one-third of an inning. Since then, the lefty has emerged as one of the Angels' top high-leverage options, posting a 1.24 ERA, 1.17 WHIP and 38:13 K:BB over 29 frames spanning 28 appearances while recording eight holds and two saves.

Detmers earned the save in Wednesday's 6-5 win over the A's, striking out two in a perfect ninth inning.

EDGE Analysis

With Kenley Jansen unavailable, Detmers was tasked with protecting a one-run lead against the top of the A's batting order in the ninth. The left-hander was up to the task, retiring the side on just 10 pitches while striking out a pair. Detmers has impressed in a high-leverage role recently -- he's now held opponents scoreless in 11 straight innings, allowing just six hits while striking out 18 in that span. Detmers has two saves on the season while lowering his ERA to 5.22 with a 1.53 WHIP and 37:13 K:BB across 29.1 innings.

Detmers earned a hold against Seattle on Saturday, allowing one hit and striking out two batters over one scoreless inning.

EDGE Analysis

Detmers handled the seventh frame with the Angels up by two runs. The left-hander began the campaign working in a lower-leverage role and had a 10.05 ERA with no holds or saves through his first 12 appearances, but since then he's turned things around, surrendering just one run over his last 12 outings covering 13 innings while posting a 19:7 K:BB. He's become one of the Angels' top high-leverage options, picking up six holds and one save across his past nine appearances.

Detmers struck out two in a perfect 10th inning Tuesday to record his first career save in a 4-3 win over the Red Sox.

EDGE Analysis

Kenley Jansen handled the ninth inning to keep the game tied at 3-3, and when the Angels pushed a run across in the top of the 10th, manager Ron Washington brought in Detmers to face Boston's 5-6-7 hitters. The southpaw was up to the task, fanning Carlos Narvaez and Trevor Story while firing nine of 11 pitches for strikes. Detmers is emerging as a high-leverage weapon for the Halos in his first season working out of the bullpen, and over his last 10 appearances he's produced a 0.82 ERA, 1.36 WHIP and 15:6 K:BB in 11 innings while racking up one win, one save and four holds.

Detmers (1-2) earned the win over the Dodgers on Saturday, allowing one run on three hits and two walks while striking out two batters over two innings.

EDGE Analysis

Detmers entered in the sixth frame with runners on second and third and no outs after Hector Neris allowed all three batters he faced to reach base. Though he yielded an infield single and a walk, Detmers did a good job limiting the damage, allowing just one of the inherited runners to cross the plate while inducing a key double play groundout off the bat of Shohei Ohtani. Detmers continued into the seventh and gave up a run of his own, but he still received credit for the win on a day when he was the most effective Angels reliever aside from closer Kenley Jansen. Detmers recently went through an awful stretch during which he allowed 12 earned runs while retiring just one batter over a three-outing span, but the lefty has been better since then, yielding just one run while posting a 5:3 K:BB across four innings over his past three appearances.

Detmers (0-1) gave up five runs on five hits without recording an out in relief to take the loss Wednesday against the Mariners.

EDGE Analysis

Detmers entered in the seventh inning with the scored tied 2-2. The lefty was initially unlucky as the first two batters he faced reach on an infield single and a bunt single, respectively, but Detmers then gave up three more consecutive knocks -- including a Julio Rodriguez double -- and was pulled having failed to record an out. In total, five runs were charged to Detmers' line, pushing his season ERA all the way up to 5.79. The first-round pick of the 2020 First-Year Player Draft is transitioning to a relief role this season and had been pitching well prior to getting blown up Wednesday, as he entered the contest against Seattle with a 2.57 ERA and 14:5 K:BB over 14 innings.

Angels manager Ron Washington said Monday that Detmers will open the 2025 season in the bullpen, Bill Shaikin of the Los Angeles Times reports.

EDGE Analysis

Detmers had been competing against Jack Kochanowicz for the final spot in the Angels' rotation. With Kochanowicz winning the job, Detmers will work out of the Halos' bullpen and could be used as a long reliever, per Jack Janes of The Sporting Tribune. Detmers worked in relief in each of his last three spring outings and allowed four runs (three earned) on 11 hits and two walks while striking out 13 across 11.2 frames.

Detmers pitched four innings in a Cactus League contest against the Padres on Sunday, allowing two runs (one earned) on four hits and no walks while striking out four batters.

EDGE Analysis

Kyle Hendricks began the game with five frames for the Angels, and Detmers followed by pitching the remaining four innings. Detmers did well despite giving up two runs, as he didn't issue any free passes and fanned four batters. The lefty is locked into a competition with Jack Kochanowicz for the final spot in the Angels' rotation, and both pitchers have made a strong case this spring -- Detmers has posted a 2.30 ERA and 12:2 K:BB over 13.2 innings while Kochanowicz has a 2.92 ERA and 7:4 K:BB across 12.1 frames. Jack Janes of The Sporting Tribune reports that the Angels are considering using whichever of the two pitchers doesn't get the rotation spot as a long reliever, though it's not clear if the team is leaning toward Detmers to come out of the bullpen since he's worked in relief in three out of his five Cactus League appearances while Kochanowicz has started in all four of his outings.

Detmers entered in the sixth inning of Monday's Cactus League contest against Colorado and tossed four scoreless frames, allowing four hits and striking out four batters.

EDGE Analysis

Detmers has been battling Jack Kochanowicz for the Angels' fifth-starter role this spring, but it's unclear if Detmers' appearance in relief Monday -- the first time he has come out of the bullpen this spring -- in an indication that Kochanowicz has won the job. Regardless, Detmers made a strong case to be on the Opening Day pitching staff in some capacity with his performance against the Reds, during which he limited Cincinnati to four harmless hits -- all singles -- across four innings. The left-hander lowered his spring ERA to 2.31 with the outing, and he now has an 8:2 K:BB over 11.2 frames, though Kochanowicz has arguably been better with a 1.00 ERA and 6:1 K:BB over nine innings.

Detmers tossed 2.2 innings in a Cactus League contest against the Dodgers on Wednesday, allowing one run on two hits and no walks while striking out one batter.

EDGE Analysis

Detmers set the side down in order in the first inning, then allowed a run on a double, single and groundout in the second. He retired the only two batters he faced in the third before his day came to an end. Detmers and Jack Kochanowicz are battling for the Angels' fifth-starter role to begin the campaign, and both have been effective in exhibition play thus far. Detmers has a 3.52 ERA and 4:2 K:BB over 7.2 frames across three outings, while Kochanowicz has a 1.80 ERA and 4:1 K:BB over five innings covering two appearances.
