The injury bug continues to plague the Cubs.

Prior to Friday’s series opener against the White Sox, David Bote slipped on a ball in batting practice on the side of the field and suffered a sprained ankle. X-rays were negative and he’ll be reassessed on Saturday.

He was originally in the lineup hitting fifth and playing second base before the injury. The Cubs replaced him with Ian Happ, who started in left field, with Matt Duffy moving from third base to second base and Patrick Wisdom moving from left field to third.

Bote was in audible pain when the injury happened, with trainers and manager David Ross tending to him. He left the playing field on his own power.

He has a .609 OPS with 8 home runs and 32 RBI this season.

Adbert Alzolay was back in Chicago after his rehab start in Iowa on Wednesday. He pitched 2 innings, allowing 4 runs on 2 hits and striking out 3.

“All good, healthy,” Ross said. “We’ll get him back soon.”

Willson Contreras played catch and took batting practice on the field prior to the game against the White Sox. He’s been out since August 12 with a sprained right knee. 

“Running through a full day of stuff today,” Ross said. “I think he’s about ready. I think he wants a couple of at-bats so might get out on a rehab, see how that goes and we’ll play it day to day.”
