The Red Sox are finalizing a trade to acquire veteran catcher Danny Jansen from the Toronto Blue Jays.

The move, first reported by MLB insider Ken Rosenthal, likely leaves Reese McGuire the odd man out. Jansen, 29, is having a somewhat down-year offensively, but he’s still in the 78th MLB percentile or better in whiff, walk, and chase rates, and has a 93 wRC+, compared to McGuire’s 59. Behind the dish, McGuire is minus-2 Blocks Above Average (23rd percentile); Jansen’s plus-11 puts him in the 98th percentile.

It’s likely a short-term add for the Red Sox. This is Jansen’s final year of arbitration, and Boston’s top catching prospect, Kyle Teel, has made a strong case for a promotion to Triple-A.

Jansen would be Boston’s second acquisition before Tuesday’s trade deadline. The Red Sox brought back veteran left-hander James Paxton in a deal with the Los Angeles Dodgers on Friday.
