The Houston Astros have added some key arms to their roster this offseason. First, they resigned Wandy Rodriguez (see the AP article). The Dominican Baseball Guy thinks Wandy is an ace or at least a number two starter. He won the Dominican Baseball Guy player of the month for August 2010. Wandy is from Santiago, DR.
Next, they signed Enerio del Rosario. He debuted for the Reds last year and should see time in the Astros bullpen this season, after he had a strong winter season in the Dominican Winter Baseball League (LIDOM). They also resigned Jimmy Paredes, who is on the 40 man roster, but will most likely start next year in the minors. Parades came to the Astros in the Lance Berkman deal. Enerio is from Santa Lucia, DR and Paredes is from Haina, DR. Brian Mctaggart reported these deals here.
Most recently the Astros resigned Alberto Arias (see the details from Sports Blog Nation Houston). Arias missed all of 2010 with an injury, but should see time in the Astros bullpen if he continues to recover from the rotator cuff injury. Alberto is from the capital of the DR, Santo Domingo.
These signings are in addition the following Dominican players on the Astros 40 man roster: Fernando Abad (La Romana, DR), Henry Villar (Bonao), Jorge DeLeon (La Cega Azua), and Aneury Rodriguez (Higuey). There are also several non-roster Dominican invitees to spring training.
