Background & Context
Los Angeles Angels right-hander Jack Kochanowicz entered 2026 as a regular starter, posting a 3.05 ERA through his first seven outings. Third baseman Yoán Moncada, signed to a one-year, $4 million contract in February, had been a modest offensive contributor before a right-knee injury sidelined him in late May.

- May 3 – Completes first seven starts (2-1, 3.05 ERA).
- May 22 – Moncada placed on the 15-day injured list for knee inflammation.
- Jun 5 – Kochanowicz exits first inning vs. Dodgers after allowing seven runs; MRI ordered.
- Jun 6 – Angels announce Kochanowicz will undergo Tommy John surgery; Moncada scheduled for knee surgery the following week.

- Kochanowicz: 13 starts, 6.19 ERA, 64 IP, 47 K, 36 BB; fastball 97 mph avg., max 99 mph; split 3.05 ERA (first 7 starts) vs. 11.91 ERA (next 6).
- Moncada: .189 AVG, .605 OPS, 3 HR, 10 RBI in 41 games; .048 AVG from the right side.

Official Statements & Responses
Manager Kurt Suzuki said the club is “thinking about our options and we’ll see who’s up today,” indicating an evaluation of rotation replacements such as left-hander Sam Aldegheri, right-handers Caden Dana and George Klassen. Suzuki added that third-base duties will shift to Denzer Guzmán while Moncada recovers, and confirmed there is “no different role” for closer Kirby Yates at this time. The organization’s formal announcement confirmed Kochanowicz’s UCL tear and upcoming Tommy John procedure.

Criticism & Opposition
Analysts note that losing Kochanowicz deepens an already thin rotation, leaving the Angels with the fourth-worst ERA and a record that threatens a historic 100-loss season. The “brutal blow” to depth underscores concerns that the club may struggle to field a competitive five-starter rotation without rapid promotion of minor-league arms.
Conflicting Reports & Gaps
Recovery timelines for Kochanowicz vary: some sources project a return “through the 2027 season,” others cite “late 2027,” while a third predicts “the second half of 2027 at the earliest” or “most if not all of 2027.” Moncada’s surgery date remains unspecified, and the list of potential rotation fill-ins differs across reports (Aldegheri, Farris, Dana, Klassen, Johnson).
Why It Matters / Impact
Kochanowicz’s absence removes a right-handed starter capable of 97-99 mph fastballs, forcing the Angels to rely on less experienced arms and potentially reshuffle bullpen roles. Moncada’s knee surgery further depletes offensive production at third base. Both injuries exacerbate the club’s depth crisis and could influence the race to avoid a franchise-worst loss total.
What’s Next
The Angels will open the next series against the Tampa Bay Rays with a re-configured rotation, likely promoting Sam Aldegheri or Caden Dana. Moncada’s rehab timetable will dictate third-base assignments, while Kochanowicz’s rehabilitation is expected to span 14–16 months, targeting a possible return in mid-2027. Future updates will hinge on medical assessments and the performance of newly called-up pitchers.
