The Astros have signed Livan Hernandez to a minor league deal, Ken Rosenthal of FOX Sports reports on Twitter. The Praver/Shapiro client would provide Houston with rotation depth if he makes the team out of Spring Training.
Hernandez posted a 4.47 ERA with 5.1 K/9, 2.4 BB/9 and a 42.4% ground ball rate in 175 1/3 innings for the 2011 Nationals. The 36-year-old has averaged 216 innings and a 4.44 ERA since 1998, his first full season as a big league starter, and has completed at least 175 innings in each of the past 14 seasons. He earned $1.25MM in 2011, but didn't obtain guaranteed money from the Astros.
