Bullpen blues for Piniella

Kevin Gregg walked three straight batters in the eighth against Arizona, including walking in a run. His ERA climbs to 6.23. Don't panic, Gregg owners, because Carlos Marmol's ERA jumped to 6.75 as he walked in two Diamondbacks earlier in the game. Gregg is the Cubs closer, Marmol is the setup man and Jeff Samardzija might be the dark horse to leap both for the closer role. Samardzija struck out two of the three Diamondbacks he faced, although he did give up a 2-RBI double to Justin Upton. Both of the runs were charged to Marmol as the Cubs lose 10-0.

Fantasy Impact: We're not speculating that Samardzija will earn the closer job imminently, but we're thinking Lou Piniella might need to get creative if he wants to solidify his 'pen. Samardzija is an intriguing talent - a hard-throwing stud with movement and a steady demeanor. If Marmol and Gregg continue to implode, Piniella's hand may eventually be forced. Keep an eye on the situation, especially if Samardzija begins to take off in his setup role.
