The Angels informed Jack Kochanowicz over the weekend that he won the fifth spot in the rotation, manager Ron Washington told reporters (including Bill Shaikin of The Los Angeles Times). Reid Detmers is going to open the year in the bullpen, though Sam Blum of The Athletic notes that he’ll stay stretched out in a multi-inning role in case he’s needed to return to the rotation midseason.
The Halos signed Yusei Kikuchi and Kyle Hendricks over the offseason. They join Tyler Anderson and José Soriano as the top four starters. Kochanowicz, Detmers and Chase Silseth entered camp as the main candidates for the final spot. Silseth dropped out of the competition quickly, as he allowed 16 runs in 13 innings. The Angels optioned him last week.
Kochanowicz and Detmers have each pitched well in camp. The former has worked 12 1/3 innings of five-run ball (four earned). His 7:4 strikeout-to-walk ratio is middling, but he’s kept the ball on the ground at a 52.4% clip. Detmers has surrendered seven runs (six earned) with 17 punchouts and four walks over 19 1/3 frames. He has gotten grounders at a solid 46.6% rate in his own right.
It seems the job was Kochanowicz’s to lose. The 24-year-old righty made his first 11 MLB appearances last season. He posted a 3.99 earned run average across 65 1/3 innings. He had fantastic control (3.8% walk rate) and got grounders at a massive 57% clip, but his 9.4% strikeout rate was the lowest among all pitchers who reached 50 innings. It’s not easy to find sustained success with that low a strikeout rate. Kochanowicz has a 5.39 ERA with a 19% strikeout rate in four minor league seasons.
Detmers, the 10th overall pick in 2020, has a lot more swing-and-miss upside. He has fanned a quarter of opponents over four MLB seasons, including a career-high 27.9% of batters faced last year. Yet Detmers’ results have been up and down. He allowed an ERA approaching 7.00 over 17 starts last season. A .357 average on balls in play didn’t do him any favors, but he also surrendered nearly two home runs per nine innings. The Angels optioned him to Triple-A. He pitched in the minors between June and September. The homer troubles continued in the Pacific Coast League, where he allowed a 5.54 ERA despite a near-30% strikeout rate.
Since Detmers has two options remaining, the Angels could have sent him back to Triple-A when they settled on Kochanowicz as their fifth starter. The 25-year-old southpaw pitched well enough this spring to ensure he’d stick on the MLB roster. The Angels swapped lefty reliever José Suarez to the Braves for right-hander Ian Anderson over the weekend.
They still need to decide whether to carry out-of-options southpaws José Quijada and Angel Perdomo in the bullpen with Detmers and Brock Burke. They’ll have righties Kenley Jansen, Ben Joyce and Ryan Zeferjahn in the later innings. Ian Anderson is out of options and seems likely to make the team in a long relief role, which would round out the pitching staff unless the Halos cut Quijada or Perdomo.
