CHICAGO -- Mike Olt leads all National League rookies with 12 home runs, but he's also first with 84 strikeouts and was batting .139 after going 0-for-4 in Tuesday night's 6-0 victory over the Padres with three strikeouts. After the game, the Cubs announced they were optioning Olt to Triple-A Iowa.
The Cubs need to open a roster spot for pitcher Tsuyoshi Wada, who will be making his second big league start Wednesday against the Padres.
Olt, acquired a year ago Tuesday from the Rangers in the Matt Garza deal, went 2-for-35 in June, and was 3-for-25 in 12 games in July. If there's a plus to the demotion, it's that he'll be reunited with Manny Ramirez, who is a player/coach at the Cubs' Triple-A team, and a former teammate of Olt's.
Before Tuesday's game, general manager Jed Hoyer was asked about Olt and outfielder Junior Lake, who was batting .216. Manager Rick Renteria has tried to start Olt and Lake against lefties.
"Their contact rates have been a struggle," Hoyer said of the two players. "They've showed some frustration at times but I do like that they keep on working to improve."
