Garza nears return as Cubs near decision

CHICAGO -- Matt Garza's next rehab start is Thursday, and it could be his last, which will create a problem for the Cubs, who have a pretty good rotation right now.

Entering play on Tuesday, Chicago's starters ranked third in the National League with a 3.40 ERA behind the Cardinals and Nationals, and had posted 23 quality starts, with a 1.90 ERA in those games.

Garza, on the disabled list with a strained left lat sustained in a Spring Training workout on Feb. 17, will make his fourth Minor League rehab start on Thursday for Triple-A Iowa.

"I'm just going for the next one," Garza said Tuesday. "I'm looking forward to Thursday, and after Thursday, we'll make a decision. They want me to get stretched out and get deeper into games, and I guess that's what I have to do now."

He threw 66 pitches in his last outing for Double-A Tennessee, but it was over 3 1/3 innings. The Cubs want him to go deeper in the game.

"I've been throwing strikes, I've been working on things I need to work on," Garza said. "It's all piecing together. I feel fine and am excited about Thursday."

But who gets bumped when Garza is ready? Over the weekend, Cubs manager Dale Sveum said they weren't considering a six-man rotation. But on Monday, he said it could be a possibility.

"It's a tough decision, because everybody has pitched pretty well," Sveum said. "It's going to be one of those things that will be unfortunate for somebody, but it's a reality and it's going to happen."

Carlos Villanueva, who started Tuesday, has the most experience as a swingman.

"It might lean to who we're playing that series, the matchups," Sveum said. "Maybe you go to a six-man rotation for a week because of matchups. You never know what the bullpen is like. A lot of things come into play. We'll make that decision -- and I know you guys are going to keep asking this question every day. It's not going to change."

Travis Wood posted his eighth straight quality start on Monday, and has a 2.03 ERA. Scott Feldman has a 2.53 ERA in his seven starts, which include a complete-game win.

"I guess that's the best problem to have," Garza said. "I want to pitch. I'm not getting ready for no reason. The guys are doing great. I've got to really step into it and gear up for it. I'm excited to come back and champing. I'm not looking forward to anything past Thursday."

Does he have a say in the matter?

"I would say a lot, based on, it's my job," Garza said. "It comes down to what the organization wants to do. Obviously, we'll sit down and talk about it after the next outing. It's all based on how I respond and how I feel and how comfortable I am."

Valbuena expected back in lineup Wednesday

CHICAGO -- Third baseman Luis Valbuena was expected back in the Cubs' lineup on Wednesday, four days after spraining the little finger on his right hand when he slid into third base.

Valbuena, who injured his hand on Saturday in Washington, has been able to take batting practice and work out at third Monday and Tuesday. He spent part of Tuesday with his little finger in a cup of ice to get the swelling down.

"[He has to deal with] the pain tolerance and the discomfort that's going to be there for a while," Cubs manager Dale Sveum said. "It's the lingering soreness to the touch-type thing. It'll be manageable."

Valbuena was batting .272 in 31 games with five home runs, five doubles and 13 RBIs.

Cubs improve with runners in scoring position

CHICAGO -- The Cubs have finally climbed above the Mendoza line when batting with runners in scoring position.

Chicago entered Tuesday's game batting .204 with RISP, still lowest in the Major Leagues. The team leads the National League with 87 doubles and 131 extra-base hits. But they rank 10th in runs scored.

"It's climbing," Cubs manager Dale Sveum said of the team's RISP average. "We're out of the hundreds and climbing towards .210 now. It is a cycle thing. Sometimes it's month to month and a team will hit .140, and then the next month, they'll hit .300 with men in scoring position.

"It's a cycle stat that hopefully everybody's bunched up at the end of the year and the really good offenses will be high," he said.

Extra bases

• Arodys Vizcaino, coming back from Tommy John surgery on his right elbow, will continue his rehab with the Cubs, rather than in Mesa, Ariz.

Vizcaino joined the team on Monday. Sveum said the right-hander, acquired from the Braves last July in the Paul Maholm deal, was a couple weeks away from appearing in a game.

Scott Baker, who also is rehabbing from Tommy John surgery one year ago, remained in Mesa at the Cubs' facility.

• Cubs top prospect Jorge Soler was named Florida State League Player of the Week. In four games with Class A Daytona, he was 7-for-15 with three doubles, a triple, two home runs, four RBIs and scored five runs. He has reached base in 10 consecutive games.
