The White Sox announced today that left-hander Carlos Rodon has been placed on the 10-day injured list. He’ll be replaced by right-hander Lucas Giolito, who was activated to take the ball this evening. 

Right-hander Dylan Covey will ultimately move into the White Sox rotation to take Rodon’s place for whatever duration he’s sidelined.

Rodon is dealing with an “edema in the flexor mass,” reports James Fegan of The Athletic (via Twitter). That initial diagnosis doesn’t provide a clear picture of Rodon’s outlook, but it seems as if there’s some reason for worry here. “Everything is on the table,” GM Rick Hahn told reporters, including Dary Van Schouwen of the Chicago Sun-Times (Twitter link) when asked about the possibility of Tommy John surgery.

Rodon had been off to an uneven opening to the season. He’s averaging 11.9 strikeouts per nine innings, nearly twice the rate he managed last year. He is carrying a personal-best 12.1 percent swinging-strike rate despite losing a full mph on his average fastball. Going to his four-seamer instead of his sinker may be helping generate whiffs, though Rodon has seen year-over-year rises in hard contact and batting average on balls in play.
