The Cardinals have signed left-handed pitcher Rob Kaminsky to a minor league contract for the 2025 season, the team announced. This will be the 30-year-old’s third stint with the organization and his 12th professional campaign.
Kaminsky first signed with St. Louis in 2013 as the 28th overall pick in the draft. Despite his young age – he made his pro debut at 18 – the southpaw impressed right away. Over his first three years in the Cardinals system, he threw 217 1/3 innings between Rookie ball and High-A, pitching to a 2.15 ERA and 2.90 FIP.
St. Louis traded Kaminsky to Cleveland ahead of the 2015 trade deadline, in exchange for Brandon Moss. It was after the trade that Kaminsky began to struggle, and questions about his ability to stick in the rotation began to arise. Following a 2017 season almost completely lost to injury, he pitched exclusively out of the bullpen in 2018 and ’19, compiling a 3.31 ERA and 4.01 FIP in 84 1/3 innings pitched. While his numbers were solid (if unspectacular), he had largely fallen off of top prospects lists by that time. He elected minor league free agency after the 2019 season.
Kaminsky re-joined the Cardinals on a minor league pact that winter and made his MLB debut the following summer. He pitched 4 2/3 innings in 2020, striking out three and walking two. He gave up three runs, although only one was earned. Despite his serviceable results, the Cardinals DFA’d him after his fifth appearance in September. He has not returned the to major leagues since.
From 2021-24, Kaminsky bounced from the Phillies to the Mariners to the Staten Island FerryHawks of the Atlantic League and back to the Mariners. He dealt with various injury issues in that time and struggled to make much of an impact when he did take the mound. That being said, it’s worth noting that he made eight starts at Triple-A Tacoma in 2024. It was the first time he had made more than two starts in a season since 2016. Kaminsky is highly unlikely to make the Opening Day roster, but he will offer the Cardinals some left-handed depth for the bullpen, and possibly the rotation, too. Perhaps a return to his former club will help him get back on track as he strives to return to the majors in 2025.
