The Chicago White Sox sent closer Addison Reed to the Arizona Diamondbacks in exchange for Triple-A third baseman Matt Davidson, the teams announced Monday.
Reed, 24, saved 40 games in 48 chances last season with a 3.79 ERA and 72 strikeouts in 71 1/3 innings.
Davidson, 22, a former first-rounder who has been ranked among Baseball America's top 100 prospects, played at Triple-A Reno last season.
In 115 games for Reno, Davidson hit .280 with 32 doubles, 17 homers and 74 RBI. In 31 games for the D-Backs, he hit .237 with six doubles, three homers and 12 RBI.
The trade comes one week after the White Sox sent pitcher Hector Santiago to the Los Angeles Angels and received center fielder Adam Eaton from Arizona in a three-team swap.
