Rios was selected by the New York Mets in the 26th round of the 2003 draft. The Santa Ana, Calif. native played four seasons for New York, climbing up four different levels and getting as high as Class-AA Binghamton. Rios has spent the last four years in independent ball: 2007-08 with Sussex of the Can-Am League, and 2009-10 with Joliet of the Northern League. The 29-year old has registered his best years as a pro during his last two campaigns. He hit .297 and earned a spot on the Northern League All-Star team in 2009, and set career highs in runs scored (59), doubles (25), home runs (7), RBI (53), stolen bases (7) and walks (33) last season. Primarily a shortstop but with experience at every infield position, Rios played collegiately at NAIA Concordia University in Irvine, Calif., where he was an honorable mention All-American.
