As a member of the D-backs two years ago against the Astros, Snyder homered on a Felipe Paulino 96-mph fastball that easily cleared the tracks in left field, measuring around 460 feet.
"That was by far my best ball hit," said Snyder. "That's all there is in the tank. Definitely the power was supplied, and it all connected on one spot."
Snyder's three-run home run on Tuesday against the Mets' Jonathon Niese gave the Astros a 5-0 lead en route to a 6-3 win. But Snyder has struggled in his first season in Houston, batting .139 entering Wednesday's game.
Except for last year, slow starts are the norm for Snyder, who isn't concerned about his early-season struggles at the plate.
"I know what kind of player I am, and I've been that kind of player my whole career," said Snyder, who hit 16 home runs for Arizona in 2008. "I'm not trying to do anything more, anything else. I'm playing the game like I know how to play it. I'm not worried."
