Per MLB.com:
The Rays will get pitcher Alexander Torres and third baseman Matthew Sweeney in return in the deal, which is expected to be announced later today.
Sweeney is a 21-year-old left-handed bat who plays third base but will probably end up at first. He's a big guy, 6'3" and packs about 215 pounds. He'll remind you of Aubrey Huff. The story on him is power and walks. In 240 High-A plate appearances he's hit .300/.381/.519 in the Cal League where the league average is .270/.341/.416. He missed 2008 with an ankle injury, so who knows how good his defense is, but he's not sticking at third with the Rays anyways. The problem with Sweeney so far is that he can't stay healthy.
Torres is also 21-years-old and left-handed. Right now he's in Double-A where he's struck out about a batter per inning. He gets groundballs thanks to a good sinking fastball. He's small (5'10") with some control issues in tow.
And now MLB.com says it fell through.
And now Joel Sherman says it's definitely done.
