While many clubs thought Carroll's development would have been better served had he attended college, the Mariners liked him enough to make him a third-round pick in 2007 and gave him a $315,000 bonus so he'd eschew the chance to play for UC Irvine. Carroll finished among the Arizona League leaders in several offensive categories during his pro debut, but he scuffled wildly in his follow-up in 2008. Much of his trouble can be attributed to him playing through two fractured bones in his left wrist, the result of being hit by a pitch. He didn't have surgery and the fracture set itself, though it hampered his ability to swing the bat without pain. Managers, coaches and evaluators share in their admiration for the high-energy Carroll, whom they describe simply as a baseball player. He's a plus runner who led all Seattle farmhands with 38 stolen bases in just 79 games last year. He's also an above-average defender with a strong arm in center field, but he'll go only as far as his bat will take him. Carroll has below-average power, but he has solid hitting instincts and a repeatable swing, lending hope that he can hit for average and draw walks. As such, he profiles as an extra outfielder with a ceiling as a regular in center field.
Not many teams rated Carroll highly enough to draft him in the third round like the Mariners did, but his early returns have Seattle excited. He signed for $315,000, eschewing his commitment to UC Irvine, and finished in the top five in the Arizona League in batting (.323), hits (65), steals (27) and on-base percentage (.415). Teammates nicknamed him "Machine" for his ability to repeat his swing with ease and for his highenergy disposition. Simply put, Carroll is a baseball player. What he lacks in present strength, he makes up for with above-average pitch recognition, contact ability and speed. Carroll is an above-average runner with plus instincts both on the bases and in center field. His arm is strong enough that he could handle right field. Carroll could be an ideal No. 2 hitter, using the whole field and having potential gap power as he gets stronger. He's ready for an assignment to Wisconsin.

He should be able to stay in center field thanks to average speed and fine instincts, and his plus arm would play in right field. "He plays with polish and energy," Hunter said. "He's got good hands at the plate, good speed and plays a good center field."
