The Cubs recalled Alcantara from Triple-A Iowa on Wednesday, Taylor McGregor of Marquee Sports Network reports.
Alcantara, 22, has slashed .278/.353/.428 with 14 home runs and 14 stolen bases between Double-A Tennessee and Iowa this season. He's one of the Cubs' most physically-gifted prospects, although questions remain as to how much he'll ultimately hit. It's not clear how frequently Alcantara will play this week, but there could be a path to at-bats if Seiya Suzuki's ankle injury Tuesday forces him to miss some time.
