Pittsburgh did this as they traded for San Diego Padres right-handed relief pitcher Ron Marinaccio<\/a>, sending International Signing Bonus Pool considerations the other way and placing their new reliever on the 26-man roster and 40-man roster, taking the spot of Santana.<\/p>\n It’s a disappointing end to Santana’s tenure with the Pirates, one that was largely successful until later on in this campaign.<\/p>\n Where it all Went Wrong for Santana<\/p>\n The Pirates claimed Santana off waivers from the New York Yankees on June 11, 2024, and he became one of their better pickups, dominating over the rest of that season and throughout 2025.<\/p>\n He posted a 2.28 ERA over 114.1 innings pitched in 109 games, with 110 strikeouts to 28 walks, a 0.89 WHIP and a .184 batting average allowed in those first two seasons with the Pirates, making him a key arm and the best in a strong bullpen for the team in 2025.<\/p>\n Sep 27, 2025; Cumberland, Georgia, USA; Pittsburgh Pirates pitcher Dennis Santana (60) pitches the ball against the Atlanta Braves during the ninth inning at Truist Park. Mandatory Credit: Jordan Godfree-Imagn Images | IMAGN IMAGES via Reuters Connect<\/p>\n Santana kept up those good performances through the first month of the season, posting a sub-1.00 ERA and solidifying himself as a key high-leverage option, either as a closer or setup man with left-handed pitcher Gregory Soto.<\/p>\n He came into one save opportunity against the St. Louis Cardinals<\/a> at PNC Park on April 27, up 2-0 and looking to close out a contest that the rest of the bullpen had dominated in and even took a perfect game into the seventh inning.<\/p>\n Santana instead gave up back-to-back home runs, tying the game up at 2-2, and then the Cardinals took the lead off a two-run RBI double and eventually took the 4-2 win.<\/p>\n One bad outing doesn’t necessarily mean that a pitcher will regress and lack the efficiency they once did, but this blown save for Santana was the start of everything going wrong for him.<\/p>\n Dennis Santana Pre-Blown Save then Afterwards<\/p>\n Stat<\/p>\n Pre-Blown Save<\/p>\n Blown Save-End<\/p>\n ERA<\/p>\n 0.69<\/p>\n 8.48 <\/p>\n Innings Pitched\/Games<\/p>\n 13.0\/13<\/p>\n 28.2\/31<\/p>\n BAA<\/p>\n .116<\/p>\n .308<\/p>\n WHIP<\/p>\n 0.85<\/p>\n 1.47<\/p>\n K\/BB<\/p>\n 10\/6<\/p>\n 27\/15<\/p>\n HR<\/p>\n 0<\/p>\n 8<\/p>\n Santana would have a few good games, but his poor performances always overshadowed his better outings.<\/p>\n Some of these include giving up four straight hits in the 10th inning in the eventual 11-9 loss to the Philadelphia Phillies at PNC Park on May 15 and giving up three runs in the eighth inning, making a 3-2 deficit a 6-2 loss to the Toronto Blue Jays<\/a> at the Rogers Center on May 22.<\/p>\n More struggles became consequential in July, particularly his series vs. the Atlanta Braves<\/a> at PNC Park. <\/p>\n Santana gave up a two-run home run to former Pirates catcher Joey Bart in the eighth inning of an eventual 3-0 defeat on July 8 and then gave up a grand slam in the ninth inning to Braves right fielder Mike Yastrzemski, making a 6-5 deficit a 10-5 defeat.<\/p>\n He also gave up a two-run walk-off home run to Cleveland Guardians second baseman Travis Bazzana in the 5-3 loss in the second game of the doubleheader at Progressive Field on July 18, his first outing post-All-Star break.<\/p>\n Santana had just one outing after that, coming against the New York Yankees at Yankee Stadium on July 20, where he turned a double play and then almost started a fight<\/a> with shortstop Jos\u00e9 Caballero over his pitch clock antics.<\/p>\n One thing you can say about Santana was that he didn’t go down without a fight, although, the Pirates would’ve hoped that translated into better outcomes on the mound.<\/p>\n A Deeper Look at Santana’s Struggles<\/p>\n Santana’s ultimate demise with the Pirates this season shows up not just in those poor outings, but throughout every part of his game.<\/p>\n His advanced metrics show a drop-off in the quality of his pitches and also the precipitous fall in efficiency in his other stats too. <\/p>\n Apr 27, 2026; Pittsburgh, Pennsylvania, USA; Pittsburgh Pirates relief pitcher Dennis Santana (60) reacts before being removed from the game during the ninth inning against the St. Louis Cardinals at PNC Park.
