Nationals' Alberto Baldonado: Jumps to big leagues

The Nationals selected Baldonado's contract from Triple-A Rochester on Wednesday.

Baldonado earned his first big-league call-up after he submitted a 3.23 ERA, 1.11 WHIP and 31:8 K:BB in 30.2 innings with Rochester following his promotion from Double-A Harrisburg. The 28-year-old lefty is expected to fill a low-leverage role out of the Washington bullpen in September.
