Yankees promote Aaron Gershenfeld to major league staff after Tanner Swanson’s exit

The Yankees are promoting Aaron Gershenfeld to their major league coaching staff after Tanner Swanson left to become the Mariners’ bench coach. The move aims to preserve the club’s work developing catchers, particularly their ability to frame pitches, an area in which Swanson had played a leading role.

Gershenfeld was the Yankees’ run prevention and catching coordinator and worked with catchers in both the major and minor leagues. Swanson helped Austin Wells become a Gold Glove finalist this season, and the club considers Gershenfeld important to that progress. Other staff questions remain: pitching coach Matt Blake is returning after signing an extension, while bench coach Brad Ausmus has interviewed for the Astros’ managerial job.
