Scott Carroll (fingernail) is expected to be OK to make his next scheduled start on Tuesday.
Carroll dealt with a cracked fingernail in his last outing, but White Sox manager Robin Ventura said Tuesday that the righty "looks OK." If it turns out Carroll can't go, it's possible the club will move up Chris Sale to start, which would give him an extra outing as he pursues the AL Cy Young award.
David Peralta (back) is not expected to return before Friday.
The rookie outfielder has been sidelined with back discomfort since September 5. Peralta resumed all baseball activities earlier this week but apparently still hasn't made the necessary progress in order to return.
Rockies recalled RHP Eddie Butler from Double-A Tulsa.
Butler will start for the Rockies on Saturday. The righty struggled in his major league debut back in June and hasn't posted overly impressive numbers in the minors this season (3.99 ERA, just 69 strikeouts over 117 1/3 innings). However, he remains a top pitching prospect and might be worth a flier in NL-only formats.
Rays recalled LHP C.J. Riefenhauser from Triple-A Durham.
Riefenhauser has spent almost all season at Triple-A Durham, holding a 1.40 ERA while striking out 53 across 57 2/3 innings. He'll give the Rays another lefty option in the bullpen.
Josh Willingham struck out as a pinch-hitter in his return to action Tuesday.
Willingham hadn't played since last Thursday, when he suffered a strained groin. It's not clear when he'll be ready to start, but the pinch-hitting appearance suggests he's close.
