Collin Cowgill has been waiting a long time for his first full-time opportunity in the big leagues.The former Kentucky All-American spent his first four professional seasons with Arizona, earning a spot on the Diamondbacks’ postseason roster after a dominant season in Triple-A. The next year, he appeared poised to start after being traded to Oakland, but was squeezed out of a starting role by other offseason acquisitions.Before 2013, he was acquired by the New York Mets, who named him their starter in center field early this spring. Leading off for the Mets on opening day, he did not disappoint.In an 11-2 win, Cowgill had a pair of hits in five at-bats. The first was a fourth-inning double (he later scored) and the second was a grand slam to left that turned the Mets’ game against the San Diego Padres into a laugher. Here’s video of his third-career major-league home run.

More Cowgill!!! WOW!!!!!!! @ccowgill12 first career grand slam and second by a Met on Opening Day. Todd Hundley in ’95 was the other.
