Royals left-hander Kris Bubic is closing in on his first major league work since undergoing Tommy John surgery last April. The Stanford product began a rehab assignment last month and has made seven starts between Double-A and Triple-A.
While Bubic has worked from the rotation in the minors thus far, that won’t be his role with the big league club. General manager J.J. Picollo tells MLB.com’s Anne Rogers that the Royals are moving Bubic to the bullpen for now (X link). He has a week and a half left on his rehab assignment, so he’ll begin working in relief at Triple-A Omaha.
The assignment probably doesn’t come as a shock. While the 6’3″ southpaw has been a starter for essentially his entire career, Kansas City already has a defined front five. Cole Ragans, Seth Lugo, Brady Singer, Michael Wacha and Alec Marsh have taken all but four of the team’s starts this season. Ragans, Lugo and Singer have been varying degrees of excellent. Wacha is having his typically solid year, turning in a 4.07 ERA with plus control. K.C. signed him to fill that role as an innings eater and certainly isn’t bumping him from the rotation while he’s pitching this effectively.
Marsh is arguably the one question mark of the group. The second-year righty overcame a 15.9% strikeout rate to turn in a 2.70 ERA during the first month of the season. He dramatically increased the whiffs and ran a 3.86 ERA behind a 27.4% strikeout percentage in May. The wheels have fallen off over the past couple weeks, though. Marsh’s strikeout rate has normalized in between the levels of his first two months and he has allowed 6.66 earned runs per nine in June. He dominated the Yankees for seven scoreless innings on June 13 but has allowed at least three runs in the other six of his most recent seven starts.
If the Royals wanted to push Bubic back into the rotation, Marsh was the only one who might’ve been bumped. His overall body of work is still solid — a 4.40 ERA with average strikeout and walk rates — so the Royals will push Bubic to the bullpen instead.
Productive as their starting five has been, Kansas City’s relief group has been a weakness. They entered play Monday ranked 22nd in the majors with a 4.43 earned run average. No bullpen has recorded fewer strikeouts (17.5%) or missed fewer bats on a per-pitch basis (8.9% swinging strike rate). Picollo has already made clear the front office will try to add some firepower via trade.
Bubic isn’t the kind of power arm the front office has been seeking. His fastball sits in the low-90s and he leans on a low-80s changeup, not a power breaking ball, as his go-to secondary pitch. Yet Bubic had flashed bat-missing upside just before his elbow gave out. He ran a massive 14.7% swinging strike rate and punched out 23.5% of opposing hitters over his first three starts in 2023. Bubic’s elbow never gave him a chance to prove he could sustain that extra level.
The early returns on his rehab stint have been promising. Bubic owns a 2.14 ERA in 21 innings with Omaha, where he has fanned nearly 26% of opposing hitters.
Wonder if he shaved his Bubic hair
it’s pronounced “boob itch”.
and his fastball was consistently 96-97 in his prior relief appearances. 89-92 as a starter.
I said before the season started he should be a reliever.
