I've been more frustrated the year with Revere not taking the extra base much more often than giving one up because of the arm. Somebody mentioned earlier that everybody goes first to third, I say except for Revere. I don't know what it is but it doesn't seem like the baserunning is nearly as good as it should be for someone with his speed. I just picked through some stats, Revere has gotten first to third 3 times in 17 chances this year. For comparison, Prince Fielder is 4/21 with 2 throw outs. To answer the question, the arm hasn't bothered me at all while there are a couple of games won strictly because of his range.
