The Seattle Mariners solidified their Opening Day roster on Saturday by sending relief pitcher Arthur Rhodes to the minor leagues, according to The Sports Network. Rhodes has a career record of 75-60 with a 4.31 earned run average in seasons with the Orioles, Mariners, Athletics, Indians, and Phillies.

The Astros released Woody Williams on Friday. Williams, who will make $6.5 million this season, was not immediately available for comment. "From a veteran standpoint, he deserved every opportunity," Manager Cecil Cooper said. "We just didn't get there. I'm sure Woody is probably just as disappointed as anyone he didn't quite get to where he wanted to be."

The Rays placed outfielder Rocco Baldelli on the 60-day disabled list Friday and filled his roster spot by claiming outfielder Nathan Haynes off waivers from the Angels, as reported by the Associated Press.

The Red Sox have released catcher Doug Mirabelli, as reported by the Associated Press. He was placed on unconditional waivers Thursday despite his ability to handle the knuckleball that had made him Tim Wakefield?s personal catcher for several years. The skill Kevin Cash showed in catching Wakefield?s knuckleball last season makes him the likely replacement for Mirabelli.
