June 1, 2025 10:17 PM : The Padres activated Waldron (oblique) from the 60-day injured list and optioned him to Triple-A El Paso on Sunday, Kevin Acee of The San Diego Union-Tribune reports.
Analysis: Waldron had been on the shelf throughout the 2025 campaign while recovering from a left oblique strain, but after completing a rehab assignment, he'll make regular turns out of the El Paso rotation. In his most recent outing for the Triple-A club Friday, Waldron struck out six over four innings but allowed four runs (three earned) on seven hits and three walks. The knuckleballer spent most of 2024 in the San Diego rotation, turning in a 4.91 ERA, 1.26 WHIP and 133:40 K:BB in 146.2 innings. He could be an option to return to the big-league rotation later on in 2025 if he can find some success with El Paso.
