Mystery Twin No. 2, as Nick Nelson correctly surmised, was Ben Revere, the rather controversial first-rounder from the 2007 draft.
Revere is a non-roster invitee with little chance of making the big club. He's ticketed for Double A New Britain. But he's apparently made a strong impression on Ron Gardenhire, who recently made a vague comparison to Kirby Puckett and Torii Hunter:
"He reminds me of a few other guys that have come through that center field area out there, with big smiles on their faces and very confident that they can really hit and (are) not afraid of anything."
Double A to start the season — but if some disabling injury should happen to Denard Span in midseason, Revere may well get the call.
Revere is a small outfielder — listed at 5-foot-9 and 160-some pounds, which may be generous. Of the five scouting tools, he's got three, at least two of them in abundance. He can run — his foot speed is said to be comparable to Carlos Gomez. He can hit — his lowest batting average on three levels of the minors is .311. He can field.
Throwing and hitting for power — those are issues. Particularly the power. He had just 19 extra base hits last season (high A ball) in 517 at-bats. His isolated power — slugging percentage minus batting averages — was a mere .058. Fort Myers is a notably difficult place to hit for power, but that's not a good number.
The throwing arm is less of a concern. Johnny Damon and Mickey Rivers were/are notoriously weak throwers, and that didn't stop them from being quality center fielders on quality teams. I'm coming to the opinion that it might be better to have a weak arm and know it than to have a cannon and constantly try to prove it. Damon knows he's not throwing anybody out, so he hits the cutoff man and keeps the double play in order. Delmon Young repeatedly tries to throw out lead runners and surrenders bases to trail runners.
It's too soon to tell if Revere is a future star, regular or reserve. He does enough things well enough that he's going to play in the majors.
