Outfielder prospect Jhostynxon Garcia started his rehab assignment with Single-A Bradenton on May 1 and has swung the bat exactly as the Pirates would've hoped he did, with some great power so far. Garcia has hit three home runs with Bradenton and slashed .278/.300/.833 for an OPS of 1.133 in five games on his rehab assignment, with five hits in 15 at-bats, four runs scored and six RBI.
