Asuaje's contract was selected from Triple-A El Paso on Wednesday.
He was named the Pacific Coast League's Rookie of the Year after leading all Triple-A players this season with 172 hits and being tied for first with teammate Manuel Margot with 98 runs scored. He hit .321/.378/.473 with nine home runs and 10 steals (in an extreme hitting environment), playing primarily second base while also seeing time at third base and left field. It remains to be seen if his slight 5-foot-9, 160-pound frame will allow him to barrel big league pitching, but given the Padres' lack of quality infield depth, he should get a chance to prove himself over the rest of the season and in the first half of 2017.
