SAN DIEGO -- Some of the Cubs top prospects are at Triple-A Iowa.
Shortstop Javier Baez, 21, second baseman Arismendy Alcantara, 22, and third baseman Christian Villanueva, 22, are some of the charges Ramirez, who was hired by the Cubs Sunday morning to be a player coach for the Cubs' Iowa affiliate, will be asked to mold as a hitting coach.
"Manny's going to be around some of our top hitting prospects," Epstein told a group of Cubs beat writers Sunday. "It's relatively low risk for us. It's something that if it doesn't go well, we can terminate. I think it will go well. It's important."
• Mike Olt is the first rookie to hit nine home runs for the Cubs before June 1 since Geovany Soto had nine before June 1, 2008. Olt is only the 11th Cubs rookie since 1933 to have nine homers before the All-Star break. Olt's nine homers are six more than any other National League rookie and his 24 RBIs are double the next highest count by a National League rookie.
• Junior Lake didn't get a hit Saturday night, ending his hitting streak at nine games, which equals the longest of his career and is the longest by a Cub this season. But infielder Luis Valbuena homered Saturday night to extend his hitting streak to eight games, which matches the longest streak of his career. Valbuena is 13-for-30 during his streak.
