Cubs third baseman Ian Stewart will begin the season on the disabled list with a strained left quadriceps.
Stewart had not played for the Cubs this spring and re-injured the quad during a minor-league game last week.
The team also announced Tuesday that right-handed starting pitcher Scott Baker, returning from elbow-reconstruction surgery, will be sidelined after developing fluid in the elbow from his first spring start on Sunday.
Baker had elbow surgery this time last year while with the Minnesota Twins.
Baker started against the Oakland A's on Sunday and retired just one batter, giving up three runs and three hits, including a three-run homer by Chris Young.
Cubs 5, Rangers 4: Alfonso Soriano and Darwin Barney each homered off Alexi Ogando and the Cubs beat the Texas Rangers in Mesa, Ariz.
Johan Yan walked Wellington Castillo before Soriano hit his third long ball of spring training in the first inning. Anthony Rizzo added a sacrifice fly in the first.
Barney homered with one out in the second.
Texas scored twice in the first two innings against left-hander Chris Rusin. But Rusin settled down and allowed just one hit in his three remaining innings.
Reds 10, White Sox 6: Chris Heisey and Jay Bruce hit consecutive home runs. and the Cincinnati Reds tagged John Danks and the White Sox in Goodyear, Ariz.
Brandon Phillips singled twice in his first game since returning to the Reds from the World Baseball Classic. Cincinnati roughed up Danks for 10 runs on 11 hits and two walks in 3 1/3 innings.
Heisey hit a three-run homer in the third inning and finished with four RBIs. Bruce followed with his fourth spring homer.
Adam Dunn hit a long three-run homer off Homer Bailey in the first. Bailey pitched 4 1/3 innings, just short of his scheduled five after allowing five runs and nine hits.
