The Chicago Cubs have placed 37-year old righty starting pitcher John Lackey and 28-year old righty set-up man Hector Rondon on the D.L. Lackey is on the D.L. with a strained right shoulder, retroactive to August 15th. Lackey has pitched in 24 games (all starts) for the Cubs so far this year and he is 9-7 with a 3.41 ERA and a 1.04 WHIP. Lackey has given up 122 hits and 43 walks while whiffing 156 batters in his first 158 1/3 innings for the Cubs this year. Rondon is on the D.L. due to a right triceps strain, retroactive to August 17th. Rondon has pitched in 45 games (0 starts) for the Cubs so far this year and he is 2-3 with 18 saves, a 2.47 ERA and a 0.80 WHIP. He has given up 29 hits and 6 walks while whiffing 51 batters in his first 43 2/3 innings for the Cubs this year. The Cubs hope that Lackey and Rondon only miss a couple of weeks as they are both very important to the success of the team.
