The Chicago Cubs have called up 40-year old righty reliever Joel Peralta. Peralta pitched in 5 games (0 starts) in AAA-ball for the Cubs this year and he was 0-0 with 2 saves, a 4.50 ERA and a 0.75 WHIP. Peralta also pitched in 26 games (0 starts) for the Mariners earlier this year and he was 1-0 with a 5.40 ERA and a 1.33 WHIP. To make room in the pen for Peralta, the Cubs have sent 24-year old lefty reliever Gerardo Concepcion to AAA. Concepcion pitched in 3 games (0 starts) for the Cubs this year in his first taste of the majors and he was 0-0 with a 3.86 ERA and a 1.29 WHIP. Concepcion might get another shot with the Cubs later this year.
