The Chicago Cubs have had just moderate success in developing bullpen pieces for the future but one bright spot has been the progress shown by setup man Pedro Strop.

The 27-year-old reliever has a 2.29 ERA with seven holds in 20 games and has been a solid part of the team's restructured bullpen. Only James Russell and Hector Rondon have been in the bullpen from Opening Day on. Three closers later Kevin Gregg hammered down the back end job with 25 saves in 29 opportunities.

But Gregg will be a free agent after the season posing the question whether Strop is ready to take over the closer role.

"He has closer stuff" Cubs manager Dale Sveum said. "The other part is with young guys can they handle those last three outs?"

Strop had moderate success with the Orioles only to bottom out with some bad outings before getting traded with Jake Arrieta for Scott Feldman on July 2.

"Early in the year with Baltimore things were not going the way I wanted them to" said Strop who had a 7.25 ERA in 29 games with the Orioles. "It was my fault. I was not making good pitches or hitting my spots. Luck-wise I was giving up a lot of crazy base hits. You know broken bat hits and flares. Because things were not going my way I kind of lost some confidence and began rushing my game. I started to change my mechanics and got really wild."

Since coming to the Cubs Strop has worked with pitching coach Chris Bosio and bullpen coach Lester Strode on regaining his tool set and belief in his ability.
