Quick, show of hands: Who had Matt Duffy as a leading contender in this year's National League Rookie of the Year race?
Put your hand down.
Coming into the season, few outside the Bay Area so much as knew Duffy's name. And even the staunchest San Francisco Giants boosters couldn't have seen him as anything more than a fringe roster candidate.
Baseball, though, has a funny way of upending expectations. And as we enter the final two months of the 2015 campaign, there are few if any rookies contributing more than the Duffman.
