The Cubs have placed 31-year old lefty reliever John Grabow on the 15-day disabled list with knee tendinitis. Grabow has pitched in 23 games (0 starts) for the Cubs this year and he is 0-3 with a 9.45 ERA and a 2.15 WHIP. He has given up 32 hits (5 homers) and he has walked 11 batters in only 20 innings this year which is downright pathetic. The Cubs have called up 23 year old righty starter/reliever Andrew Cashner who was their #4 rated prospect heading into this year according to Baseball America. Cashner will work out of the pen for the Cubs. He has pitched in 11 games (9 starts) in AA+AAA-ball this year and he is 6-1 with a 2.05 ERA and a 0.95 WHIP. He has only given up 39 hits in 57 innings this year while whiffing 59 batters. The Cubs have a big need in the bullpen and they hope that Casher is ready to rock from day #1.
