Ramirez will start for the Pirates against the Reds on Thursday, Danny Demilio of PittsburghBaseballNow.com reports.
Thursday will be the first start of Ramirez's major-league career, with his last start taking place in 2023 with Triple-A Indianapolis. He'll likely pitch one or two innings before handing things over to Hunter Barco, who was recalled from Indianapolis on Wednesday, per Demilio. Ramirez has a 3.21 ERA, 1.38 WHIP, six holds, one save and a 62:33 K:BB across 56 innings this season.
