CHICAGO -- Rookie Rafael Dolis has teammate Starlin Castro's support to handle the Cubs' closer duties.
"He's an amazing guy," Castro said of Dolis, who is sharing the job with James Russell for now. "He's working hard, too. Every day. He watches a lot of movies every day, but he works hard."
Movies? Dolis is trying to improve his English by watching English-language films. On Tuesday, it was "Contraband." That's how Castro improved his English.
OK, back to baseball. What can Dolis do?
"He's got a hard sinker, 96 [mph], and you don't need more than that," Castro said. "Sometimes he has a pretty good slider. He doesn't need to throw that, because he has an amazing sinker. He'll be pretty good. He still has to work pretty hard. One day, he'll be good."
• Anthony Rizzo hit a pair of three-run homers to back Chris Rusin and lead Triple-A Iowa to a 13-2 win over Fresno Tuesday night. Rusin struck out five, and retired the first nine batters he faced. He gave up three hits and two walks over six innings. Rizzo connected in the first and the sixth, and he leads the Pacific Coast League in home runs with nine. This was his fourth two-homer game of the season.
• Catcher Steve Clevenger, on the disabled list with a strained right oblique and fracture in his rib cage, was able to play catch on Tuesday. Clevenger has been sidelined since April 26.
