Jose Miguel Vallejo Andujar is a professional baseball player from the Dominican Republic who plays as a Second Baseman. Vallejo was made a part of the Texas Rangers in 2005 when he began playing in the Rookie League with the Phoenix Rangers. A .291 batting average after 52 games meant that he was put directly into the A-League with the Clinton Lumber Kings.
Vallejo began his Lumber Kings career in the short stop position however, after just 2 games, was back as the familiar second baseman for 127 games for the Lumber Kings. While his batting average dropped to .234, Vallejo had 116 hits to his name and remained in the Lumber Kings for another season. In 2007, Vallejo again appeared for the Clinton team in the A-Division and in 129 games, batted at .269 to earn promotion to the Advanced A- Division. After 75 games at .287, Vallejo moved up to the AA-Division, to the Frisco Roughriders, where he had a .297 batting average in 64 games.
A move up to the AAA-Division seemed eminent and after just 20 games in the AA-Division in 2009, Vallejo was bumped up to the AAA-Division to play with the Oklahoma RedHawks.
It was in 2009 that Vallejo made the move to the Houston Astros after 84 games for the Oklahoma-based team, making just one appearance with the Portland Beavers in 2009 before being named to the 40-man MLB roster for the Astros.
