 Biographical Information
Deolis Guerra reached AAA in 2010, at age 21, then took until 2015 to make his major league debut.
Guerra originally signed with the New York Mets in 2005 at age 16. The scout was Rafael Bournigal. The right-hander made his pro debut with the Hagerstown Suns in 2006, going 6-7 with a 2.20 ERA and .208 opponent average. Promoted to the St. Lucie Mets, he was 1-1 with a 6.14 ERA in two late-season starts. Baseball America rated him as the #11 prospect in the South Atlantic League, right after Dexter Fowler. Had he qualified, Guerra would have been second in the SAL in ERA behind Matt Maloney.
The young Venezuelan spent 2007 with the St. Lucie club, going 2-6 with a 4.01 ERA. Baseball America rated him the #2 Mets prospect and #8 overall in the Florida State League between Ian Kennedy and Jose Tabata. He pitched for the World team in the 2007 Futures Game, allowing one homer to John Whittleman in the 5th and retired the other two batters he faced before being replaced by Franklin Morales.
Deolis was part of a blockbuster deal that winter, traded with Kevin Mulvey, Philip Humber and Carlos Gomez to the Minnesota Twins for Johan Santana. He was assigned to the Fort Myers Miracle, where the big right-hander was 11-9 with a 5.47 ERA.
Turning 20 years old in 2009, Guerra split time between Fort Myers (6-8, 4.69) and the New Britain Rock Cats (6-3, 5.17). In 2010, he went 2-10, 6.24 for New Britain but still got to reach AAA, where he was 0-3, 6.84 with the Rochester Red Wings. Things went slightly better in New Britain in 2011 (8-7, 5.59), but his results were still far from major league quality. He had been mainly a starting pitcher up to that point, but given his stall, he was moved to the bullpen in 2012, and seemed to turn a corner. He began that year with New Britain, and after posting an 0.71 ERA in 7 games, to go along with a 2-0 record and a save, he returned to AAA Rochester. The rest of the year, he was 2-3, 4.87 in 29 games. He was on the Venezuelan national team roster for the 2013 World Baseball Classic but was one of their two pitchers who did not get into a game (José Mijares was the other). He suffered a big setback that summer, as he missed almost the whole season with an injury, being limited to 3 games and 4 innings with the GCL Twins. In the 2014 Caribbean Series, he tossed two hitless, walkless, scoreless innings for the Navegantes del Magallanes, fanning 3 and getting a win. In 2014, he was healthy again and pitched 36 times for Rochester, with a record of 2-2, 4.33. He did strike out 54 opponents in 52 innings. He
He became a free agent after the 2014 season and signed with the Pittsburgh Pirates. Something seemed to click when he joined the Indianapolis Indians at the start of the 2015 season, as he went 2-1, 1.53 with 4 saves in 29 games to receive the long-awaited call-up to the Show. The Pirates selected his contract on June 26th when Rob Scahill went on the disabled list and he made his debut the next day, pitching the final inning of an 8-4 win over the Atlanta Braves.
