The White Sox announced that they have placed outfielder Eloy Jimenez (high right ankle sprain) and reliever Nate Jones (right elbow inflammation) on the 10-day injured list, retroactive to Saturday in both cases. The club recalled left-hander Aaron Bummer and righty Thyago Vieira in corresponding moves.

There’s no timetable for the return of Jimenez, whom the White Sox will re-evaluate in two weeks, Bruce Levine of 670 The Score tweets. They’re left to hope the 22-year-old makes it back in relatively short order thereafter, and Jimenez seems optimistic that will be the case.

“Yeah, it feels much better,” he said Sunday (via Scott Merkin of MLB.com). “The first day, I couldn’t even walk. Now, I feel better. I can walk better. There’s no pain a lot now, just a little bit.”

Jimenez is one of the keys to Chicago’s rebuild, someone the team signed to a six-year, $43MM guarantee before he ever set foot on a major league diamond. And though Jimenez has gotten off to a slow start as a rookie, having hit .241/.294/.380 with three home runs in 85 plate appearances, that subpar production shouldn’t dampen the enthusiasm about his long-term outlook.

Jones’ latest ailment is troubling considering the laundry list of injuries, including to his pitching arm, he has battled during his career. Now 33, Jones has been among the game’s finest relievers at times, though this season has been another story. While Jones owns a 3.48 ERA and a 51.7 percent groundball rate in 10 1/3 innings, he has accompanied those respectable figures with a dip in velocity and declining strikeout, walk and swinging-strike rates (8.71 K/9, 6.1 BB/9, 9.1 percent).
