Rodriguez was originally signed at the age of 15 as an amateur free agent by the Baltimore Orioles in. He played mostly as a second baseman as he moved his way slowly up through the Orioles organization, not reaching the Triple-A level for even a partial season until. After another full season at Double-A with the Charlotte O's in, Rodriguez returned to Triple-A for good in with the Rochester Red Wings. That was the season in which Rodriguez got his first chance at the majors. Called up in September when rosters expanded, Rodriguez appeared in 11 games for the Orioles, seven of them at second base, and went 7-for-17 for a batting average of.412. That would be the end of his career in the Orioles' organization, however, as he was traded to the San Diego Padres for fellow infielder Fritzie Connally.
Padres and Cardinals
Rodriguez lasted just one season in the Padres' system, playing for the Las Vegas Stars in and batting.312. He became a free agent after the season and signed with the St. Louis Cardinals, and spent the next two seasons with their top farm team, the Louisville Redbirds. By this time, Rodriguez had been shifted from second base to third base defensively.
Twins
After the season, he again became a free agent, signing with the Minnesota Twins during the offseason. He spent all of and with their Triple-A team, the Portland Beavers, before finally getting another chance in the majors. Called up in July to fill in for the injured Wally Backman, Rodriguez again posted impressive batting numbers, going 5-for-11 with 2 doubles for a.455 batting average and.636 slugging average. However, he was sent back to the minors in early August.
Minor leagues
That proved to be the end of Rodriguez's major league career. He remained in the Twins system for two more seasons, continuing to play for the Beavers. In, he moved on to the Philadelphia Phillies, playing two seasons for the Scranton/Wilkes-Barre Red Barons. In, he played for the Edmonton Trappers in the Florida Marlins' system, then finished his career playing for the Boston Red Sox' top farm club, the Pawtucket Red Sox, in. After his playing career ended in with the Pawtucket Red Sox, Rodriguez remained in the Red Sox organization as a minor league coach and instructor for 17 seasons, including seven years as roving minor league hitting coordinator and four as Latin American field coordinator of instruction.
Major league coach
On November 30, 2012, the Red Sox appointed Rodriguez as their assistant to the hitting coach. Following manager John Farrell's dismissal on October 11, 2017, Farrell's coaches were told they were free to seek employment elsewhere. Four weeks later, Rodriguez succeeded Matt Quatraro as the Indians' assistant hitting coach.
