Radhames Liz (born October 6, 1983 in El Seybo, Dominican Republic) is a relief pitcher who plays for the Baltimore Orioles. He is 6'2", weighs 185 lbs, and throws right-handed.
Liz, who is one of 8 children in his family, started playing baseball when he was 16 years old and learned how to pitch in 2003 and 2004 while playing in the Dominican Summer League. He started pitching in the United States with the short-season Aberdeen IronBirds and Single-A Delmarva Shorebirds in 2005.
In 2006, Liz started his first full professional season with the Frederick Keys, the highest of the Orioles' three Single-A teams. Liz began the season by striking out 33 batters in his first 15 innings pitched. Later in the year, he represented the Orioles on the World squad at the All-Star Futures Game. He also received a promotion to the Double-A Bowie Baysox; between the two teams, he struck out 149 batters in 133 1/3 innings before playing in the Dominican Winter League. However, he had difficulty with his control in the 2006 season, walking 75 batters. Baseball America named Liz the Orioles' fifth-best prospect going into the 2007 season, following Billy Rowell, Brandon Erbe, Nolan Reimold, and Pedro Beato.
