Out since July 26 with a high-grade calf strain, Senga had hoped to return during the Mets’ final road trip before the postseason as either a short-inning starter or as a reliever. He threw 15 pitches during his first and only rehab start Saturday with Triple-A Syracuse, striking out two without giving up a hit while issuing one walk.

After the calf injury, Senga kept trying to come back, even if it meant a shortened start in one of the Mets’ final games next weekend in Milwaukee. Senga was that good in 2023, when he went 12-7 with a 2.98 ERA in 29 starts, made the National League All-Star team and finished second in the Rookie of the Year race.
