Kameron Misner slugged a walk-off homer on the first pitch of the ninth inning, and the Tampa Bay Rays won their first outing in their new Tampa home on Opening Day by edging the Colorado Rockies 3-2 on Friday.Playing at Tampa’s Steinbrenner Field instead of St. Petersburg’s hurricane-ravaged Tropicana Field dome, the lefty-swinging Misner lined a 97 mph fastball from Victor Vodnik (0-1) out to right for his first big-league homer as the Rays made themselves home in their first-ever game in Tampa.It was just the second Opening Day walk-off homer in Rays’ history. Carl Crawford hit the other in 2003, a three-shot that provided Tampa Bay with a 6-4 win over the Boston Red Sox.Jose Caballero singled in a run and Jonathan Aranda had an RBI as Tampa Bay posted seven hits by seven players.Closer Pete Fairbanks (1-0) pitched a scoreless ninth.Over 85 pitches, Tampa Bay starter Ryan Pepiot allowed two runs (one earned) on six hits in six innings. He fanned eight, walked one and hit a batter.The National League West club wasted a brilliant start by Kyle Freeland, who faced just 20 batters over six scoreless frames and 67 pitches. He allowed two hits, struck out seven and did not have a single three-ball count.Colorado’s Ryan McMahon was 3-for-3 with a double and a walk. Ezequiel Tovar went 2-for-4 with a double and an RBI, while Hunter Goodman had two hits. Jordan Beck scored and stole two bases.
