Loses in MLB return
Kolek (3-5) took the loss Tuesday against Miami, allowing three runs on eight hits and one walk with five strikeouts across 5.2 innings.
Analysis
Kolek returned after over two weeks at Triple-A El Paso to make Tuesday's start, and he fell one out short of his third quality start of the campaign. He's now allowed at least three runs in five of his last six starts, and he hasn't exceeded five strikeouts in nine outings. The 28-year-old has a 4.28 ERA across 73.2 big-league innings in 2025. If Kolek sticks in the rotation, his next start would likely come Sunday at St. Louis.

Latest Fantasy Rumors
Could remain in rotation
Kolek is likely to stick in the Padres rotation for the near future after Michael King was placed on the injured list Sunday with right shoulder inflammation.
Analysis
Kolek figures to have a solidified spot in the rotation with King on the shelf. It was possible Kolek was going to be the odd man out sooner than later due to Yu Darvish being on a rehab assignment as he works his way back from elbow inflammation. Now with King injured, Kolek should stick around for a little while longer. Kolek has pitched to a 2.84 ERA, 1.26 WHIP and 21:8 K:BB in 25.1 innings thus far.
