The Padres pulled Castillo off his rehab assignment at Triple-A El Paso after he experienced renewed discomfort in his left forearm during his appearance Saturday, Kevin Acee of The San Diego Union-Tribune reports. Castillo was evaluated by team doctors in San Diego on Monday, but it's unclear what the medical staff concluded after its examination. In any event, Castillo's shutdown will push back any potential activation from the 60-day injured list, which was initially expected to come later this week.
Castillo (forearm) allowed two runs on two hits while recording one strikeout in two-thirds of an inning Monday as he took the loss in a rehab appearance for High-A Lake Elsinore. The 23-year-old's second rehab appearance of the season was less than ideal from a production standpoint, but it's promising to see him back on the mound. His first appearance went much more smoothly, as he allowed no hits and recorded two strikeouts in one inning pitched. Castillo likely has several weeks until he returns to the Padres, but he's on the right track.
Castillo (2-2) was the winning pitcher after firing a scoreless inning with a strikeout against the Reds on Thursday. Starter Eric Lauer was only deployed for four innings, so the official scorer deemed Castillo's scoreless appearance worthy of the victory. Kirby Yates and Craig Stammen are firmly entrenched as the Padres' top late-inning options, but Castillo is making a strong case for a larger role next year after posting a 2.67 ERA, 0.86 WHIP and 11.6 K.9 over 30.1 innings.
Castillo fired a clean inning with three strikeouts while picking up a hold in Thursday's victory over the Cubs. The 22-year-old has fired 3.2 scoreless innings with two walks and four strikeouts since being activated from the disabled list July 28. The Padres didn't move veteran relievers Kirby Yates or Craig Stammen at the deadline, so Castillo will resume his role as a middle reliever. The rookie has looked impressive in the majors so far, posting a 2.20 ERA and 12.1 K/9 over 16.1 innings this season.
Castillo (hamstring) was activated from the 10-day disabled list ahead of Saturday's tilt with Arizona, Jeff Sanders of The San Diego Union-Tribune reports. Castillo will return to action after landing on the disabled list July 7 with a right hamstring strain. In 13 games out of the bullpen this season, he's posted a 2.84 ERA and 0.79 WHIP with 18 strikeouts over 12.2 innings.
