CINCINNATI — Billy Hamilton stepped into the batter’s box and was determined to get home, one way or another. Quickly, the speedster wound up scoring the winning run. Hamilton hit the first walkoff homer of his career, connecting for a solo shot with two outs in the bottom of the ninth inning that sent the Cincinnati Reds over the Milwaukee Brewers 5-4 Monday. “I was going to hit a home run if it landed in play any way,” Hamilton said.
