The Reds acquired infielder Wilson Valdez from the Phillies for minor league pitcher Jeremy Horst on Wednesday, another move to add depth to their bench. The Reds also announced that they had signed utility player Willie Harris, a free agent from the Mets.

The Red Sox have traded shortstop Marco Scutaro to the Rockies, according to an ESPN.com report on Saturday. The Red Sox received right-handed pitcher Clayton Mortensen in return. Mortensen, 26, is a former first-round sandwich pick in 2007 by St. Louis, who sent Mortensen to Oakland in the deal for outfielder Matt Holliday.

The Indians acquired right-hander Kevin Slowey from the Rockies on Friday for minor league reliever Zach Putnam and cash considerations. Cleveland general manager Chris Antonetti claimed the deal was not a direct reaction to Fausto Carmona's arrest in the Dominican Republic on charges the pitcher falsified his identity to play in the U.S. However, the timing of the trade seems to indicate the Indians don't know if they'll have Carmona this season.

The Rockies have traded outfielder Seth Smith to the Athletics for right-hander Guillermo Moscoso and left-hander Josh Outman. Monday's deal came a day after Smith and the Rockies avoided arbitration by agreeing to a one-year contract worth $2,415,000. Smith has spent the last three seasons with the Rockies, playing both left and right field, and has a .275 batting average with 51 homers and 181 RBIs in 487 major league games.

The Cubs have acquired first baseman Anthony Rizzo from the Padres. Chicago added Rizzo in a deal that sends right-hander Andrew Cashner to San Diego. Rizzo batted .331 with 34 doubles, 26 home runs and 101 RBIs in 93 Triple-A games last season. He had a very solid 1.056 OPS. He struggled in his callup to the Padres, batting .141 in 128 at-bats, but it was the 22-year-old's first exposure to the big leagues. The Cubs also get right-hander Zach Cates, 22, who pitched at Single A last season, in the trade.

The Rockies have acquired manager Jim Tracy's son, a minor league infielder, from the Rangers. Chad Tracy was traded on Thursday for right-hander Greg Reynolds, the No. 2 selection in the 2006 out of Stanford. Tracy, 26, hit .259 with 26 home runs and 109 RBIs for Triple-A Round Rock last season. He receives a non-roster invitation to spring training.

The Orioles have obtained outfielder Jai Miller from the Athletics, who parted with the part-time player for cash considerations. Miller was designated for assignment by Oakland on Dec. 23 after the A's received four players for pitcher Gio Gonzalez. The 26-year-old went 3 for 12 with a homer and two RBIs for Oakland last season after being called up in September.

The White Sox have traded reliever Jason Frasor back to the Blue Jays for a pair of minor-league right-handers. Toronto dealt Frasor to Chicago five months ago. "It felt like I was never coming back. (His July 27 trade) was an emotional day. I think it was the first time I'd cried since I gave up five runs in Atlanta a couple of years ago," Frasor said. "It's hard to believe I'm going back to Toronto. My wife is thrilled, it's great. What a thrill, I don't know else what it say, and I can't wait to put on those new uniforms," he added.
