CHICAGO -- White Sox right-hander Dylan Covey departed Arizona Fall League competition with Glendale due to right arm fatigue. Covey had a 5.25 ERA over three starts and 12 innings.
"There certainly wasn't any reason to push through it this late in the year," White Sox director of player development Chris Getz said. "The point of having him out there to begin with really was because he missed a significant amount of time and we view him as a starter, so it was an opportunity to get some more innings."
Covey, a Rule 5 Draft selection from Oakland, finished 0-7 with a 7.71 ERA for the 2017 White Sox. He was limited to 18 games (12 starts) due to a left oblique strain.
Outfielder Tito Polo, who was acquired in a trade sending Player Page for David Robertson, Tommy Kahnle and Todd Frazier to the Yankees, also left early from the AFL. Polo had a tooth taken out and was going to miss five or six days due to an ensuing infection so the White Sox decided to get his offseason going after 30 at-bats for Glendale.
Polo's departure opened up a Glendale roster spot for White Sox outfielder Charlie Tilson, who was 0-for-4 in his first AFL game.
