PITTSBURGH -- Rookie Rafael Dolis is out for now as the Cubs' closer. James Russell and possibly Shawn Camp will share the role, manager Dale Sveum said on Sunday.
Dolis, who had taken over for Carlos Marmol, hit a batter with the bases loaded in the ninth inning on Saturday to force in the Pirates' game-winning run in a 3-2 win over the Cubs.
"That's the frustrating thing ... the back end of the bullpen is giving it up because of walks and hit batters," Sveum said on Sunday. "Nobody is hitting the ball and doing things. We're imploding by walking guys and hitting guys."
Dolis, 22, gave up a single and walked two batters before he hit Matt Hague with a pitch.
"It's a combination of youth and being put in a situation he probably shouldn't be put in, for obvious reasons," Sveum said of Dolis, who was projected to be one of the Cubs' setup pitchers this season but was switched after Marmol struggled.
"It's funny because he started out doing a nice job," Sveum said of Dolis. "Now, it's a combination of making sure you repeat the mechanics that he has in the bullpen. He's throwing great bullpens, and he gets on the mound and wants to recoil and fall off and do these things. It's a matter of being able to get on the mound, no matter what inning it is or how many outs, and repeat your delivery and throw back-to-back quality pitches."
Russell has four career saves, none this year. Camp is 10-for-23 in save opportunities in his career.
"We'll see how it all pans out," Sveum said. "Hopefully, [Matt] Garza throws nine innings and we won't have to worry about it."
Marmol, currently on the disabled list with a strained right hamstring, will make his second rehab outing on Sunday for Triple-A Iowa and could join the Cubs on Monday or Tuesday when they open a brief three-game homestand against the Padres.
