Nationals option outfielder Brian Goodwin and pitcher Sammy Solis (with lineups)

VIERA, Fla. - The Nationals have optioned outfielder Brian Goodwin to Triple-A Syracuse and left-handed pitcher Sammy Solis to Double-A Harrisburg.

Goodwin, 24, had not appeared in an exhibition game this spring as he continues to rehab from offseason surgery on his left shoulder, his non-throwing shoulder. Goodwin returns to Syracuse, where he hit .219 with four homers and 32 RBIs last season. The Nationals selected him with the 34th pick in the first round of the 2011 First-Year-Player Draft. Baseball America ranks him as the Nationals' 10th-best prospect.

Solis, 25, was in his first big league spring training with the Nationals. The 6-foot-5 lefty is fully recovered from 2012 Tommy John surgery. Previously, Solis hadn't pitched above high Single-A. The Nationals drafted him in the second round in 2010. Solis gave up two earned runs on seven hits with one walk and five strikeouts in 4 1/3 innings this spring.

Speaking of prospects, the Astros will start Mark Appel, the top pick in the 2013 First-Year Player Draft, against the Nationals today.

Ian Stewart starts at third base for the Nats. In eight exhibition games, Stewart is hitting .400 (6-for-15) with two homers and three RBIs. The seven-year veteran is getting more reps as Anthony Rendon continues to rest his left MCL sprain.
