"I would say I plan on giving him every other day [off] and will increase his playing time to two days in a row, maybe three," Cubs manager Rick Renteria said. "I have to let it play itself out first."
Alcantara had an MRI on his right wrist and was wearing a brace on Tuesday. He slammed into the brick wall in right-center catching Kristopher Negron's ball in the eighth inning. The Reds had a runner on and two out, and there was no score in the game.
"Somebody was saying somebody forgot to tell him there's a brick wall behind the ivy," Renteria said of Alcantara. "That's a game-saving play. He gave tremendous effort, [ran a] great line, very smooth, explosive action and got to it and was able to make the catch."
It was an exceptional play for Alcantara, who began this season as a second baseman.
"His immersion into center field was a pretty easy transition, in terms of chasing balls down, reading balls off the bat," Renteria said. "He's continued to learn where to throw the ball, how aggressive to be with certain plays. He's continued to improve. That's a testament to him because he's taken on a lot."
• Edwin Jackson, sidelined with a strained right lat, will make his first start since Aug. 20 on Friday when the Cubs play host to the Dodgers at Wrigley Field. Jackson, who will likely face Clayton Kershaw, threw an extended side session as a tune-up. Rookie Eric Jokisch will be available to piggyback because Jackson was not expected to go deep in the game.
