Twins first baseman Justin Morneau will be in the lineup on Opening Day against the Blue Jays on Friday, according to an ESPN.com report. Morneau missed the last three months of the season with a concussion and played in just eight spring training games while working his way back.

Angels first baseman Kendrys Morales resumed baseball activities Tuesday after experiencing no setbacks following a batting practice session the day prior. Morales, who will start the season on the disabled list as he recovers from surgery on his lower left leg, was examined by a doctor Tuesday morning. "We had no surprises," Angels manager Mike Scioscia said. "The next step for him is running on the ankle and taking ground balls."

A decision has finally been made, Giants closer Brian Wilson isn't yet healthy enough to pitch. He will start the season on the disabled list with a strained oblique muscle on his left side. Wilson, who has been dealing with tightness in his back, underwent a successful bullpen session on Tuesday, marking the first time he has thrown off a mound in nearly two weeks. "He felt great today," manager Bruce Bochy said. "I'm very encouraged with his progress, and we'll decide tomorrow his next move. I don't think he'll start the season with us, but it's good to see him feeling good, and he's letting it go." San Francisco can backdate his stint on the DL, meaning he won't have to miss the first 15 days of the regular season.

Curtis Granderson is still hopeful that he'll be ready to play when the Yankees open their 2011 season against the Tigers on Thursday. "Everything feels good," Granderson said after taking "six or seven" at-bats in a simulated game. The outfielder has been sidelined for a week by a strained internal oblique on the right side of his abdomen and had not swung a bat against live pitching since the injury. "Faced lefties, righties, everything felt good," Granderson said. "Swings and misses, check swings, all good. So I'm even more excited about tomorrow, and if everything's good, I'll get out of there Wednesday night." If Granderson can't go, then Brett Gardner becomes the starting center fielder.

Astros left-hander J.A. Happ left Tuesday's exhibition game against Triple-A Oklahoma City with a strained right oblique muscle. Happ says he is still planning to start Sunday against Roy Oswalt and the Phillies. He felt the strain while he was warming up before the third inning.

The Phillies will be without closer Brad Lidge for three to six weeks as he recovers from shoulder trouble. The team said on Tuesday that the right-hander will not require surgery to fix the injury. Philadelphia manager Charlie Manuel is leaning towards using Jose Contreras as his closer to begin the season, but Ryan Madson could also fill the role.

The Orioles have placed right-hander Justin Duchscherer on the 15-day disabled list and cut three players to reduce their roster to the 25-man limit. Duchscherer has been limited during spring training because of stiffness in his surgically repaired left hip. Player cuts included backup catcher Craig Tatum and pitcher Zach Britton, who were optioned to Triple-A Norfolk.

Mets outfielder Jason Bay may begin the season on the disabled list with a strained intercostal muscle in his left rib cage. Bay was scratched from Tuesday's Grapefruit League game. New York general manager Sandy Alderson said a DL decision could wait until shortly before the Thursday 11 a.m. ET deadline. "We will have a move or two that we don't make until the very end," Alderson said.

Giants closer Brian Wilson isn't expected to be ready to pitch by Opening Day. San Francisco manager Bruce Bochy said Monday that Wilson's chances of playing when the regular season begins are "less than 50-50." A final decision won't be made until after Wilson throws a light bullpen session in Arizona on Tuesday. "I'll be honest. I think he's less than 50-50," Bochy said. "But we're not going to rule him out completely." Wilson strained a muscle on his left side on March 17 and also missed time early in spring training with back tightness.

Padres right-hander Mat Latos will begin the season on the 15-day disabled list with a sore right shoulder. San Diego general manager Jed Hoyer said Monday that the move would be backdated to March 22, meaning Latos would be eligible to come off the DL on April 6.
