Diamondbacks' Emmanuel Rivera: Starting at third base in Game 4

Rivera will start at third base and bat eighth Tuesday in Game 4 of the World Series against the Rangers.

This marks the first start of the Fall Classic for Rivera, who's gone 2-for-2 with a double, two RBI and two runs scored off the bench. He's filling in for the struggling Evan Longoria on Tuesday as the Diamondbacks look to even up the series.
