The Chicago White Sox have acquired right-handed relief pitcher Alex Colomé from the Seattle Mariners in exchange for catcher Omar Narváez.
 
Colomé, 29, combined to go 7-5 with a 3.04 ERA (23 ER/68.0 IP), 30 holds, 12 saves and 72 strikeouts over 70 appearances last season between Tampa Bay and Seattle. He was 5-0 with a 2.53 ERA (13 ER/46.1 IP), all 30 holds and 49 strikeouts over 47 appearances with the Mariners after being acquired from the Rays on May 25 as part of a four-player deal.
 
"We view Alex as a terrific addition to our bullpen given his experience in a number of relief roles, including closing very successfully for Tampa Bay in 2016-18 before moving into a setup role with the Mariners," said Rick Hahn, White Sox senior vice president/general manager. "Alex is going to be a very important bullpen piece for Ricky and our team over the next couple of years."
 
Colomé, 6-foot-1 and 220 pounds, became the first pitcher in major-league history to record at least 10 saves and 30 holds in one season. He ranked third in the American League in holds despite not recording his first of the season until May 28.
 
Colomé has gone 22-18 with a 3.12 ERA (118 ER/340.2 IP), 96 saves, 40 holds and 314 strikeouts over six major-league seasons with Tampa Bay (2013-18) and Seattle (2018). His 96 saves since 2016 are tied for fifth most in the majors. 
 
In 2017, Colomé became the first pitcher in Rays history to lead the league in saves with 47, six more than any other pitcher in the major leagues. He was named to the 2016 AL All-Star Team.
 
The Rays originally signed Colomé, a native of Santo Domingo, Dominican Republic, as an international free agent on March 20, 2007. He is the nephew of former Rays reliever Jesús Colomé (2001-06).
 
Narváez, 26, batted .275/.366/.429 (77-280) with nine home runs, 30 RBI and 30 runs scored in 2018, his third season with the White Sox. He hit .274 (174-634) with 12 homers, 54 RBI and 66 runs scored with the Sox after being selected from Tampa Bay in the minor-league phase of the Rule 5 Draft on December 12, 2013.
