Williams collects three hits for Ospreys

Left fielder Justin Williams, the D-backs' No. 16 prospect, homered and collected three hits on Monday, helping rookie-level Missoula defeat Helena, 8-5, on Opening Day in the Pioneer League. The game was halted after eight innings due to rain.

Williams finished the game 3-for-4 with two runs, two RBIs, a walk and a stolen base. The home run was the second of his career.

Williams was just 17 when the D-backs selected him 52nd overall in the 2013 First-Year Player Draft. He played at three levels last summer after signing, reaching Class A South Bend at the end of the season. Across all levels, he played 51 games and hit .351/.397/.452 in his professional debut.

The D-backs have returned Williams to Missoula to start this season, and he was joined in the lineup on Monday night by two members of the club's 2014 Draft class. Center fielder Matt Railey and third baseman Tyler Humphries, the D-backs' third- and seventh-round picks, respectively, earlier this month, made their professional debuts.

Railey, who was ranked No. 64 on MLBPipeline.com's list of Top 200 Draft Prospects, led off for the Ospreys and went 0-for-3 with two walks and a run. Humphries hit cleanup and went 0-for-4 with a walk and a run.
