The Chicago Cubs have placed 32-year old lefty reliever Clayton Richard on the 15-day disabled list due to a blister. He has pitched in 22 games (0 starts) so far this year for the Cubs and he is 0-1 with 1 save, a 7.30 ERA and a 2.19 WHIP. Richard has given up 21 hits and 6 walks while whiffing only 6 batters in his first 12 1/3 innings, so he has been getting hit hard this year. The Cubs have called up 24-year old lefty reliever Gerardo Concepcion to replace Richard in the pen. This will be Concepcion’s first shot at pitching in the show. He pitched in 22 games (0 starts) in AA+AAA-ball for the Cubs so far this year and he is 2-0 with a 1.29 ERA and a 0.97 WHIP. Concepcion has given up 2o hits and 14 walks while whiffing 34 batters in his 35 innings in AAA-ball so far this year. Concepcion has now pitched in 103 games (14 starts) in his first five years in the minors and he is 8-11 with 2 saves, a 4.80 ERA and a 1.54 WHIP.
