Fister placed on 15-day DL, Cole recalled from Triple-A

The Washington Nationals recalled right-handed pitcher A.J. Cole from Triple-A Syracuse and placed right-handed pitcher Doug Fister on the 15-day Disabled List with right forearm tightness on Friday. President of Baseball Operations and General Manager Mike Rizzo made the announcement. Cole, 23, entered the 2015 season ranked as the Nationals' No. 6 prospect, and the No. 91 prospect in all of baseball, according to Baseball America. The hard-throwing right-hander, who was added to the team's 40-man roster this past winter, joins the Nationals for the second time this season. He made his Major League debut April 28 at Atlanta (2.0 IP, 9 H, 9 R, 4 ER, 1 BB, 1 K). Coming off a tremendous 2014 season, in which he posted a 13-3 record with a 3.16 ERA in 25 starts between Double-A Harrisburg and Triple-A Syracuse, Cole is 0-1 with a 2.67 ERA in five starts for Triple-A Syracuse this season. Cole, who owns a Minor League career strikeout-to-walk ratio of 4.30/1, has struck out 8.9 batters per nine innings over the course of his Minor League career. A fourth-round selection of the Nationals' in the 2010 MLB First-Year Player Draft, Cole was traded to the Oakland Athletics in the six-player deal that brought left-hander Gio Gonzalez to Washington in advance of the 2012 season. The right-hander was then re-acquired by Rizzo in January of 2013, along with right-hander Blake Treinen and left-hander Ian Krol, in the three-team transaction that sent Michael Morse to Seattle. Fister, 31, is 2-2 this season with a 4.31 ERA. Since being acquired from the Detroit Tigers in Dec. 2013, Fister is 18-8 with a 2.78 ERA in a Nationals uniform.
