Nationals recall left-hander Sammy Solis and outfielder Michael A. Taylor from Triple-A Syracuse

The Washington Nationals recalled left-handed pitcher Sammy Solis from Double-A Harrisburg and outfielder Michael A. Taylor from Triple-A Syracuse on Wednesday, placed outfielder Reed Johnson on the 15-day disabled list with a left calf strain and optioned right-handed pitcher A.J. Cole to Syracuse. President of Baseball Operations and General Manager Mike Rizzo made the announcements.

Solis, 26, joins the Nationals for the first Major League assignment of his career. Should he pitch in either of the Nationals' next two games, he will become the fifth rookie to make his Major League debut this month for Washington.

Entering the season as the highest-rated left-handed pitcher in the Nationals' system (No. 15), according to Baseball America, Solis is 0-0 with a 2.25 ERA in three games for Harrisburg this season. Joining the Senators from extended Spring Training just 10 days ago, Solis struck out three batters in four innings and allowed one earned run. Over the course of his Minor League career, Solis is 12-5 with a 3.30 ERA.

A second-round selection of the Nationals' in the 2010 MLB First-Year Player Draft, Solis has consistently been rated as one of the organization's top talents. Working hard to come back from 2012 Tommy John surgery, Solis is 4-2 with a 2.58 ERA since returning in 2013.

Taylor, 24, rejoins the Nationals for his second Major League stint of the season. The dynamic outfielder started in center field for the Nationals on Opening Day, and hit .271 with a .314 on-base percentage and a .500 slugging percentage in 12 games while Denard Span completed his rehab from core muscle surgery.

In 29 Major League games, the 2014 Double-A Eastern League Rookie of the Year has hit .241 with six doubles, one triple, three home runs, 13 RBI and two stolen bases.

Taylor, who Baseball America rated as the No. 2 prospect and "Best Athlete" in the Nationals' system, as well as the No. 32 prospect in all of baseball entering the season, has appeared in seven games for Triple-A Syracuse this year. He's hit .417 (10-for-24) for the Chiefs, with a .500 OBP and .580 SLG with one double, one home run, three RBI and two stolen bases.

Johnson, 38, has appeared in 12 games for the Nationals this season, going 4-for-18 at the plate, including 1-for-7 with an RBI-double as a pinch hitter. The veteran outfielder signed a Minor League contract with the Nationals on March 30 and made the Major League roster out of Spring Training.

Cole, 23, made his Major League debut against the Atlanta Braves on Tuesday night, starting and tossing two innings in the Nationals' 13-12 comeback victory at Turner Field. Cole allowed nine runs (four earned) on nine hits and one walk with one strikeout.
