Former major league pitcher José DeLeón has passed away at age 63, according to a report from The Associated Press. His death was announced last night by the Leones del Escogido of the Dominican Winter League. DeLeón, not to be confused with the free agent pitcher who played for the Twins last season, pitched in the major leagues between 1983-95.
A native of the Dominican Republic, DeLeón entered the professional ranks in 1979 as a third-round pick by the Pirates. The 6’3″ right-hander pitched in four minor league seasons before reaching Pittsburgh. He had an impressive debut season, working to a 2.83 ERA and striking out 118 hitters in 108 innings covering 15 starts. He earned a seventh-place finish in NL Rookie of the Year balloting.
DeLeón would hold a spot in the Pirates rotation for a few seasons. He worked to a 3.74 ERA over 192 1/3 innings during his second big league campaign. He struggled to a 4.70 ERA with an MLB-leading 19 losses the next season. Midway through the ’86 campaign, Pittsburgh dealt him to the White Sox in a lopsided swap that landed future MVP finalist Bobby Bonilla.
Chicago plugged DeLeón into their rotation for the next year and a half. While he wasn’t anywhere close to as impactful as Bonilla became in Pittsburgh, he enjoyed a solid showing on the South Side. DeLeón turned in a 2.96 ERA in 13 starts after the trade in ’86 and logged 206 frames of 4.02 ball in 1987.
Over the 1987-88 offseason, Chicago flipped DeLeón to the Cardinals for reliever Ricky Horton and young outfielder Lance Johnson. He was a rotation fixture in St. Louis over parts of five seasons. DeLeón topped 225 innings in each of his first two years with the Redbirds. He had the best year of his career in 1989, pitching to a 3.05 ERA with a National League-leading 201 strikeouts across 36 starts. DeLeón again lost an MLB-worst 19 games in 1990 but rebounded with a personal-low 2.71 ERA over 28 appearances in ’91.
The Cardinals released him in August of the following season. DeLeón signed with the Phillies and remained in Philadelphia into the next year. He converted to the bullpen by 1993. The White Sox reacquired him for reliever Bobby Thigpen the next August. DeLeón reached the postseason for the only time in his career with Chicago, making two relief appearances in an eventual ALCS loss to the Blue Jays. He’d pitch in two more seasons, working with the Sox and Expos through 1995. DeLeón didn’t return to the majors thereafter, although he pitched in Taiwan until his age-37 campaign in 1998.
Over parts of 13 seasons, DeLeón tallied nearly 1900 innings while allowing 3.76 earned runs per nine. He struck out almost 1600 hitters with an 86-119 record. He surpassed 150 frames on seven occasions and donned five major league uniforms. MLBTR sends our condolences to DeLeón’s family, loved ones, friends and former teammates.
