Rays middle relief pitcher Andrew Kittredge is Thursday’s Box-Toppers spring training Player of the Day.

Box-Toppers is tracking several days of spring training during 2018 as a test and demonstration of the Box-Toppers player tracking metric. Even after 23 seasons of tracking (including sharing those results for the past five seasons on Box-Toppers.com), we need to spend a little time shagging ground balls and getting in shape for the 2,430 games to be tracked during the regular season.
