The ball left Travis Snider's bat and he took off with his head down. The Pittsburgh Pirates outfielder had imagined driving the ball into the Allegheny River since he joined the team last summer. In Snider's daydreams, the homer always went down the right field line, the shortest route out of PNC Park. Reality turned out to be even sweeter. And longer. Snider's 458-foot longball over the bushes in right-center propelled the Pirates to a 7-1 win over the Milwaukee Brewers on Thursday night. The two-run shot was Snider's first homer since last August, an eternity for a guy once considered a power-hitting prospect.
