The Red Sox and catcher Mark Kolozsvary have agreed to a minor league contract with an invitation to major league spring training, reports Kiley McDaniel of ESPN. It’ll be his second straight season with the Red Sox organization, as he was with the club’s Triple-A affiliate in Worcester in 2024.
Kolozsvary, 29, has technically appeared in two big league seasons, though he played in only one game for the 2023 Orioles and didn’t log a plate appearance. He tallied 10 games with the 2022 Reds and came to the plate 21 times, going 4-for-20 with a homer and two doubles (.200/.238/.450).
In parts of four Triple-A seasons, Kolozsvary owns just a .176/.297/.312 batting line. He’s yet to provide much in the way of offense in his big league career, but Kolozsvary is regarded as a strong defender with quality minor league marks for framing, blocking balls in the dirt and controlling the running game. He’s thrown out 29% of runners who’ve attempted to steal against him in his minor league career.
Kolozsvary is the latest depth addition for a Red Sox club that doesn’t have much certainty behind starting catcher Connor Wong. Trade acquisitions Carlos Narvaez and Blake Sabol are both on the 40-man roster, but neither has established himself in the majors yet. Narvaez has just six big league games to his credit. Sabol is a .243/.313/.392 hitter (95 wRC+) in 382 MLB plate appearances with the Giants but has fanned in one-third of his trips to the plate and struggled defensively at catcher. Boston also brought in veteran Seby Zavala as a non-roster invitee, giving them another strong defender with a shaky track record at the plate.

The $21MM in deferred money in the deal could lower the contract’s net present value below this tier of elite closer, but it’s hard to deny that Scott belongs in that elite company based on his incredible numbers the past two seasons. He was among the very best relievers in the sport last year with a 1.75 ERA, 2.92 FIP, and a 28.6% strikeout rate. His peripheral numbers were even stronger in 2023, as he struck out an eye-popping 33.9% of opponents and posted a 2.31 ERA with a 2.17 FIP. Among qualified relievers over the past two seasons, Scott ranks fourth in ERA and fifth in FIP. Only
