Cubs could mix and match with shuffled 'pen

CHICAGO -- With Kyuji Fujikawa out for the season because of elbow problems, the Cubs will need to shuffle their bullpen again.

Fujikawa has a torn UCL in his right elbow, and he will undergo Tommy John surgery. No date has been set for the procedure.

"Depth is what you need to have in the game," manager Dale Sveum said. "Everybody has their problems, everybody has their injuries. Obviously, we got hit with a big blow. Other people just have to step up and fill those roles and do the best we can."

Fujikawa had taken over the closer's job after Carlos Marmol struggled in the first week of the season. But Fujikawa then had to go on the disabled list because of a strained forearm April 10. When he returned, Kevin Gregg had taken over the closer's job, and Fujikawa was used as a late-inning setup man.

"The bullpen was solidified there, and now it'll be a little different," Sveum said. "[Rafael] Dolis is throwing the ball like he has been and [Hector] Rondon has been fine. Marmol has been doing a good job. We'll just make do and see how it all stacks up."

Marmol can be used in the late innings, depending on matchups. The Cubs also shifted Carlos Villanueva to the bullpen when Matt Garza came off the disabled list.

"We have some guys there, but it'll be a mix and match in the seventh and eighth inning with the lead," Sveum said.

Fujikawa signed a two-year, $9.5 million contract with the Cubs last December, and there is a 2015 club option that will become guaranteed based on games finished in 2014. He was a closer for 12 seasons in Japan with Hanshin. Will Fujikawa be the Cubs' closer next year?

"That's a long way away," Sveum said. "I've got enough to worry about right now than to worry about next year's closer."

Feldman escapes by learning from mistakes

CHICAGO -- The second inning nearly got out of control on Wednesday for Scott Feldman, but he remembered what he did wrong in his previous start.

The White Sox's Jeff Keppinger battled Feldman in an 11-pitch at-bat in the second and hit a single. With runners at first and third and one out, Feldman gave up an RBI single to Tyler Flowers, but he retired the next two batters and escaped.

"I just had to remember what I did wrong in Cincinnati [in his previous start] when I gave up the crooked number there, and try to minimize the damage and have confidence that if I do give up one run, we'll come back," Feldman said. "[Dioner Navarro] came right back the next inning and hit another home run."

Navarro backed up his pitcher with his first career three-homer day, driving in six runs, in the Cubs' 9-3 victory over the White Sox. Feldman didn't get to see the third blast in person. He was already doing his shoulder exercises in the athletic trainer's room.

"I was jumping around on the trainer's table, I can tell you that," Feldman said.

The right-hander is now 4-1 with a 1.64 ERA in five starts at Wrigley Field, and 5-1 in his last seven starts after opening the season 0-3.

"He was able to get through it and manage innings and make big pitches when he had to," Cubs manager Dale Sveum said. "That's one thing that he seems to do is get in a little bit of trouble, and you see the wheels come off and, bam, here's the good stuff and the location in big situations."

Extra bases

• Triple-A Iowa third baseman Josh Vitters was placed on the disabled list for the second time this season. Vitters, who missed time April 9-30 because of a lower back strain, was placed on the DL Tuesday with a strained muscle in his rib cage. In 19 games with Iowa, Vitters was batting .270 with two doubles, three homers and eight RBIs.

"It's been a frustrating injury for him," Cubs general manager Jed Hoyer said. "Hopefully he'll get through this as well."

• Cubs top prospect Javier Baez hit a walk-off home run in the 11th inning, a two-run shot, to help Class A Daytona beat Tampa, 6-4, on Tuesday. Baez is batting .268 for the season.

• On June 11, the Cubs will host "Meet the Team, Have a Ball" at Wrigley Field. The event gives fans the chance to walk on the outfield grass and collect autographs from players and coaches. Admission includes an MLB baseball, ball cube and snack. Admission is $300 per person.

On June 16, fans can participate in "Catch In the Confines" and spend 50 minutes throwing the ball in the outfield, run the bases, visit the batting cages or chat in the dugouts. The event starts at 12 p.m. CT, and additional time slots are available. Admission is $150 per participant, with $15 guest tickets.

Proceeds for both events benefit Chicago Cubs Charities. Tickets are available on Cubs.com/community.
