Polanco went 1-for-3 with a solo home run in Thursday's Grapefruit League game against the Cardinals.
The 32-year-old took Michael McGreevy deep in the first inning for the Mets' only run of the afternoon. Polanco is adjusting to a new defensive position at first base, but so far it hasn't impacted him at the plate, and through five spring appearances he's gone 4-for-12 with two homers and a 2:4 BB:K.
