The Reds on Thursday announced the hiring of Oscar Marin as their new bullpen coach. Marin, who served as the Pirates’ pitching coach from 2020-25, will take over for Matt Tracy, who’s moved from bullpen coach to assistant pitching coach. Last year’s assistant pitching coach, Simon Mathews, was hired away as the Nationals’ new pitching coach earlier this week.
Marin broke into pro ball back in 2010 with the Rangers, working as a coach and assistant in their minor league ranks for seven years. He then joined the Mariners as their minor league pitching coordinator from 2017-18 before returning to the Rangers organization as their bullpen coach in 2019.
Plenty went wrong for the Pirates during Marin’s tenure with the organization, although generally speaking, the pitching staff was far down the list of the team’s problems. Pittsburgh’s offense and struggles to develop young hitters are known flaws of the organization, but the Pirates have done well in drafting and developing young pitchers. While many Pirates top hitting prospects have stalled out in Triple-A or the majors, pitchers like Paul Skenes, Bubba Chandler, Jared Jones, Braxton Ashcraft, Mike Burrows, Mitch Keller and others have had plenty of success at the MLB level with Marin as their lead pitching instructor.
Marin was one of the Pirates’ first hires after initially tabbing Derek Shelton as their manager. Shelton was dismissed in May — he’s since been hired as the new Twins’ manager — and replaced by bench coach Don Kelly, whose contract was extended at season’s end. While Kelly and Marin have worked together for several years, the Bucs opted not to renew Marin’s contract. The Pirates hired former Astros pitching coach Bill Murphy to fill their pitching coach vacancy late last month.
The 42-year-old Marin (43 next month) will now join Terry Francona’s staff and bring more than a half decade of experience as a pitching coach — some of it spent alongside highly respected Brent Strom — to a Cincinnati team that is deep in pitching talent (albeit more in the rotation than in the bullpen at present).
