US college team's first baseball kit (4)

I believe the answer is:

mitt

'baseball kit' is the definition.
(catchers wear mitts in baseball)

'us college team's first' is the wordplay.
'us college' becomes 'MIT' (Massachusetts Institute of Technology).
'team's first' becomes 't' (1st letter of 'team').
'mit'+'t'='MITT'

(Another definition for mitt that I've seen is " Baseball glove".)

I've seen this clue in The Times.
