The Phillies selected Cairo's contract from Triple-A Lehigh Valley and optioned him to Lehigh Valley on Wednesday.

Cairo did enough this spring to earn a spot on the 40-man roster, but he will begin the season in the minors. The 24-year-old is a light-hitting infielder but gives the Phillies a versatile, stable glove at Lehigh Valley.

The Orioles placed Holliday (hand) on the 10-day injured list Wednesday.

Holliday was unable to play in any Grapefruit League games after requiring a procedure Feb. 12 to remove the fractured hamate bone from his right hand, so his move to the IL was fully expected. The 22-year-old appears to be making solid progress in his recovery, as he was able to take live batting practice last week without incident. He's likely trending toward a mid-April return from the IL.

The White Sox placed Baldwin (elbow) on the 10-day injured list Wednesday.

After Baldwin's right elbow injury was previously described as soreness, the White Sox are officially listing him with a right elbow sprain, suggesting that he's dealing with ligament damage. Even if Baldwin doesn't wind up requiring surgery, the utility player might be looking at an extended absence.

The Astros announced Wednesday that Pena (finger) will be part of their Opening Day roster, Brian McTaggart of MLB.com reports.

Pena fractured his right ring finger in early March and was held out of game action until playing in an exhibition contest Tuesday. The 28-year-old slugged a home run in that game and appears ready to roll for Thursday's opener against the Angels. Pena is set to start at shortstop and bat leadoff for Houston this season.

The Rangers placed Freeman (back) on the 10-day injured list Wednesday.

Freeman will get a late start to the season after being diagnosed with a lumbar stress reaction in late February. He will be eligible for activation in early April but could be looking at an extended absence.

The Tigers placed Sweeney (shoulder) on the 10-day injured list Wednesday.

The 25-year-old suffered the right shoulder strain at the start of camp and was unable to play in any games during spring training. Sweeney will require a rehab assignment to get some games in before returning from the IL. Even once healthy, he could be ticketed for the minors with top prospect Kevin McGonigle beginning the season as Detroit's primary shortstop.

The Astros placed Dezenzo (elbow) on the 10-day injured list Wednesday.

Dezenzo hurt his elbow while playing for Team Italy in the World Baseball Classic. There's no timetable for his return, but the fact that he was diagnosed with a sprain suggests it could be longer than a minimum absence.

The Marlins placed Acosta (oblique) on the 10-day injured list Wednesday.

Acosta will be shelved for at least the first couple weeks of the season with a left oblique strain. He could be assigned to Triple-A Jacksonville rather than the major-league club once he's healthy and completes a rehab assignment.

The Tigers selected McGonigle's contract from Double-A Erie on Wednesday.

The transaction was merely a formality after the Tigers confirmed Tuesday that the 21-year-old star prospect would be included on the Opening Day roster. McGonigle earned the right to bypass the Triple-A level and make his MLB debut Thursday in San Diego after slashing .250/.411/.477 with two home runs and two stolen bases over 56 plate appearances in spring training. He's expected to handle an everyday role while splitting time between third base and shortstop, and he could occupy a prominent spot in the batting order right away.

The Yankees placed Volpe (shoulder) on the 10-day injured list Wednesday.

Volpe is still working his way back from surgery last October to repair the labrum in his left shoulder. He's expected to be ready for a rehab assignment around the second week of April and could make his season debut around May 1. Jose Caballero will cover shortstop for the Yankees while Volpe is on the mend.
