CHICAGO -- After missing Thursday's series finale against the D-backs, Cubs shortstop Addison Russell was placed on the 10-day disabled list on Friday, retroactive to Wednesday, with a right foot strain.
In a corresponding move, the club recalled left-hander Rob Zastryzny from Triple-A Iowa.
"It's been bothering him noticeably the last couple days," Cubs manager Joe Maddon said of the strain. "We just thought it was wise to get it settled down right now, and that's what we're doing."
Russell, who was hitting just .216 through May and .228 through June, had seen his numbers climb during July. The infielder had a .267/.313/.467 slash line for the month, and he was hitting .318 over his past 13 games before missing Thursday's contest.
While the effects didn't show up in his bat, it's possible they impacted Russell's play on the field. The shortstop, who underwent tests on his foot prior to the DL stint, committed throwing errors in each of his past two games, though Maddon said he wasn't sure how much of that was due to the injury.
"He talked to me about [the strain], talked to [athletic trainer] PJ [Mainville] about it, but I was not aware of it prior to that," Maddon said. "I guess it's been ongoing, and he's probably kept it kind of quiet."
Zastryzny, on the other hand, has made just one appearance with the Cubs earlier this year, pitching four relief innings and giving up three runs in an 11-6 loss to the Yankees in May. He also made eight appearances with the Cubs in 2016, surrendering two earned runs in 16 innings and posting a 1.13 ERA.
Maddon seemed to indicate Friday that Zastryzny's stint with the Cubs could be short, pointing out the bullpen had been taxed in the series finale against the D-backs.
"We'll see how it all plays out," Maddon said. "Our pitching kind of got beaten up a little bit the last two days. In case something bad were to happen today, we needed some length."
