After only 10 days at Class AA Harrisburg, Nationals shortstop prospect Trea Turner has been promoted to Class AAA Syracuse, according to multiple people familiar with the situation. His stay at Harrisburg has been brief but he has been impressive.

Turner, 21, was the “player to be named” in the December trade between the Nationals, Rays and Padres. Because of MLB rules that have since changed, Turner couldn’t join the Nationals until June 14. In the 10 games he played with Harrisburg, Turner hit .359 (14 for 39) with a .879 OPS and four stolen bases.

Between Harrisburg and Class AA San Antonio in the Padres minor leagues, Turner hit .327 with five home runs and an .860 OPS and 15 stolen bases. Turner, the Padres’ first-round pick in 2014, is known for his athleticism, speed, baseball instincts and glove. Turner, who hit .323 last season in Class A, is seen as a potential Nationals shortstop of the future.

Turner, the second overall prospect in the Nationals system, was named Thursday to the Futures Game roster, along with Nationals top pitching prospect Lucas Giolito.

Turner is not in Harrisburg’s lineup on Thursday. Syracuse will be in Indianapolis on Friday.
