NASHVILLE, Tenn. – The Chicago White Sox added depth to their inexperienced outfield Monday, acquiring Carlos Quentin from the Arizona Diamondbacks for minor league first baseman Chris Carter.

Once considered a top prospect, Quentin batted .214 with five home runs and 31 RBIs in 81 games for the NL West champions this season. He lost his starting job in right field and was demoted to the minors in July, then recalled a few weeks later. But he missed most of August with a strained right hamstring and was left off the playoff roster.

In Chicago, the 25-year-old Quentin could get another chance to earn regular playing time, perhaps in left field. The White Sox cut light-hitting speedster Scott Podsednik last month, and right fielder Jermaine Dye is the only proven slugger in their outfield.

Carter, 20, showed power at Class-A Kannapolis this season, batting .291 with 25 homers and 93 RBIs in 126 games.

The White Sox have been one of baseball’s busiest teams this fall. After going 72-90, they traded pitcher Jon Garland to the Los Angeles Angels for Gold Glove shortstop Orlando Cabrera and signed reliever Scott Linebrink to a $19 million, four-year contract.

Chicago general manager Ken Williams was disappointed he missed out on All-Star center fielder Torii Hunter, who signed with the Angels as a free agent.

Quentin is a .230 career hitter in 138 major league games with 14 homers and 63 RBIs. He was called up to the big leagues in 2006 and batted .253 with nine homers and 32 RBIs for the Diamondbacks, getting regular playing time in right field.

He entered 2006 ranked by Baseball America as the 20th-best prospect in pro baseball and the best defensive outfielder in Arizona’s system.

Quentin was chosen by the Diamondbacks out of Stanford in the first round (29th overall) of the 2003 amateur draft. He hit .348 with four homers and 27 RBIs in 33 games with Triple-A Tucson this year.

The White Sox also designated left-hander Heath Phillips for assignment. The 26-year-old Phillips was 1-1 with a 3.68 ERA in six relief appearances for Chicago this season. He went 13-7 with a 4.30 ERA and 108 strikeouts in 28 starts for Triple-A Charlotte, throwing 173 2-3 innings.
