The Padres are expected to reinstate right-handed pitcher Trevor Cahill on Sunday, in time to make his next scheduled start. There is no word yet on what the corresponding move will be.
Cahill was placed on the 10-day disabled list on April 9th (retroactive to April 6th) with what was classified as a lower back strain. In his 2017 debut on April 5th, he threw 99 pitches over 5 2/3 innings and allowed three runs (two earned) on five hits and three walks, also striking out seven batters along the way.
Upon his placement on the DL, San Diego called up righty Zach Lee, who made his Padres debut on Wednesday against the Rockies. He put together a really impressive performance at Coors Field, especially considering it was only his second ever Major League appearance, and his first since 2015. He threw 5 1/3 scoreless innings, keeping the Rockies to only two hits and four walks (plus three strikeouts) and leading the Padres to their fourth ever shutout at Mile High.
According to Dennis Lin of the San Diego Union-Tribune, Lee will return to long relief when Cahill returns, so the question remains about who the Padres will send down to make room on the 25-man roster. Signs point to Kevin Quackenbush, who returned to the big league club on Friday and still has options at this point.
