If Alex Rodriguez were as unsuccessful on the baseball field as he proved to be in the legal arena, then no one would care about him in the first place. A-Rod dropped his third and final lawsuit on Thursday, his medical malpractice suit against Yankees doctor Christopher Ahmad and New York Presbyterian/Columbia University Medical Center. Rodriguez’s attorney Alan Ripka and spokesman Ron Berkowitz both confirmed that the case had been discontinued in Bronx court and reiterated the disgraced slugger’s desire to return to action with the Yankees next year. “All legal matters have been resolved,” Berkowitz said Friday. “Alex looks forward to taking the field in 2015.” The 38-year-old Rodriguez has kept nearly totally silent since independent arbitrator Fredric Horowitz reduced his Major League Baseball suspension from 211 games to the entire 2014 season for his involvement with Biogenesis, the now-shuttered South Florida anti-aging clinic. The Yankees have Rodriguez signed for three more years and $61 million, ending in 2017. In January, Yankees managing general partner Hal Steinbrenner called A-Rod “an asset” when healthy and wouldn’t rule out a scenario in which Rodriguez once again played for the Yankees.
