PHOENIX -- Andrew Cashner, who is being considered for the rotation, will make his first Cactus League start Saturday when the Cubs face the Padres.

Cashner went two innings in his first spring appearance on Monday against the Brewers and gave up two runs on three hits.

The right-hander pitched in 53 games in relief last season when called up to the big leagues but is being stretched out this spring. Chicago manager Mike Quade has named Ryan Dempster, Carlos Zambrano and Matt Garza for the first three spots in the rotation but is still sorting out the rest.

Randy Wells, another rotation candidate, will follow Cashner on Saturday.

Rehabbing Guzman encouraged by live session

PHOENIX -- Cubs pitcher Angel Guzman, trying to come back from right shoulder surgery, threw 20 pitches in a live batting practice session on Wednesday at HoHoKam Park in Mesa, Ariz., and was encouraged by the results.

Guzman, who last faced hitters in September 2009, was able to throw all his pitches -- fastball, changeup and cutter. He isn't ready to pencil himself into the Cubs' plans for 2011 just yet. It's a long process.

"I still need to throw more," Guzman said.

"Miracles can happen," Cubs manager Mike Quade said Tuesday. "Let's see if he can't get healthy and get back throwing the way he did."

Guzman has been limited to 88 games in four seasons because of arm injuries. In 2009, he totaled 61 innings over 55 games and compiled a 2.95 ERA.

Extra bases

Alfonso Soriano hit a sixth-inning opposite-field home run in the Cubs' 12-5 loss to the Brewers on Wednesday. That could be a sign of things to come. "Now I don't have to worry about getting healthy," Soriano said. "I have more time to think about my defense and offense. I worked so hard in the Dominican this winter, and now I'm working hard with Rudy [Jaramillo, hitting coach] in the cage, and I want to hit the ball more to right field this year." ... Outfielder Fernando Perez remained sidelined Wednesday with a bruised left shoulder. He injured it making a diving catch on Monday. ... Braden Looper will make his first Cubs spring appearance on Thursday against the Rangers, following Carlos Zambrano, who will be making his second start. Looper sat out last season and last pitched in the big leagues in 2009 with the Brewers. ... The Cubs Wives will hold their 14th annual food drive to benefit Paz de Cristo on Sunday at HoHoKam Stadium. The first 500 fans who make a donation of 10 non-perishable food items or $20 will be able to randomly select a 5x7 autographed photo of a Cubs player. A silent auction also will be held during the food drive.
