PHOENIX — It didn't take long for Tommy Troy to make an impact with the Arizona Diamondbacks on Sunday.

The 24-year-old prospect was called up Saturday after outfielder Lourdes Gurriel Jr. landed on the injured list with a left hamstring strain. While the news of Gurriel Jr.'s injury wasn't ideal, Troy took advantage of the opportunity to play at the MLB level for the first time and ran with it.
Against the Colorado Rockies, the rookie went 2-for-4 with two doubles and two runs scored in the Diamondbacks' 9-1 win. His first career hit was a double to left-center field in the second inning, and he later added another extra-base hit.
Arizona fans were encouraged to see this type of production and immediate impact from another young homegrown player.

The D-Backs fought to break out of a slump that had plagued them for several series, but they have now won their last three series, including this weekend's against Colorado. Much of that success has come from rising rookies and emerging young talent quickly adapting to the demands of the major leagues.
Troy, despite playing only one game, helped the club secure the series victory with timely hits and speed on the bases.
It also showcased the versatility and composure that have made Troy one of the organization's top prospects. His patient at-bats and ability to handle veteran big-league velocity with power showed that what he accomplished in the minors is beginning to translate at the MLB level.

Of course, like with any player, one game doesn't guarantee long-term success. Pitchers will adjust, and consistency remains the biggest challenge for any rookie trying to establish himself in the majors, especially once injured players make their way back from the IL.
Still, Troy's debut gave fans reason for encouragement. It was another sign that Arizona's developmental system has prepared its prospects to handle sudden call-ups and contribute immediately. If Sunday was any indication, Troy could become the latest young piece to provide a spark for a Diamondbacks team looking to keep momentum as the season continues.
