The 30-year-old catcher remain shelved to begin the season before starting up a rehab assignment in the Florida State League shortly after the All-Star break.

Nets NRI deal with Phillies Kolozsvary (undisclosed) agreed to a minor-league contract with the Phillies on Friday that includes an invitation to spring training, Will Sammon of The Athletic reports.

Impact Kolozsvary appeared in just 30 games between Double-A Portland and Triple-A Worcester in the Red Sox organization in 2025 before landing on the full-season injured list in June. The Phillies don't have a clear replacement for free agent J.T. Realmuto behind the plate, but regardless the 30-year-old Kolozsvary hasn't made an appearance in the majors since 2022 and should be viewed as a long shot to break camp.
