In documents filed in Manhattan federal court, Rodriguez's lawyers informed the court that he had dropped two lawsuits against Major League Baseball, one challenging an arbitrator's decision to suspend him for the 2014 season and one accusing baseball investigators of unethical behavior.
The papers did not offer an explanation.
The filings likely mean that the Yankees third baseman will sit out the entire 2014 season.
Rodriguez's attorney, Joe Tacopina, told Reuters on Friday that Rodriguez would not attend spring training with the Yankees.
The players' union, which Rodriguez also had targeted in court for failing to provide him adequate representation, issued a statement praising the slugger for doing "the right thing".
In one lawsuit, Rodriguez claimed that arbitrator Frederic Horowitz showed "blatant partiality" toward MLB when he suspended Rodriguez last month for 162 games, or the entire 2014 season, costing him $25 million in salary.
That suspension, the longest ban related to alleged doping in baseball history, was reduced from the 211 games the league had originally handed down.
Major League Baseball had accused Rodriguez of obtaining testosterone, insulin growth factor and human growth hormone from 2010 to 2012 from Anthony Bosch, the owner of a now-defunct Miami anti-aging clinic called Biogenesis.
Rodriguez had filed a separate lawsuit last year accusing MLB investigators of intimidating witnesses and buying evidence.
Harvey Eager To Throw
"Things are going really smoothly now," Harvey said Friday on WFAN.
Harvey, 24, said he hasn't had any setbacks during rehab, keeping him in line to hit the typical four-month mark between undergoing surgery and the start of throwing.
Harvey believes Feb. 22 will be his target date to throw "once (doctors) give me the OK."
Until then, Harvey's work will remain in the weight room, where he is steadily increasing his workload.
The righthander underwent surgery on Oct. 22 after weeks of debating whether to attempt rehab instead.
Tanaka A No. 3 Pitcher
Tanaka, 25, recently signed a seven-year, $155 million deal with the team.
"We view him to be a really, solid consistent No. 3 starter," Cashman said. "If we to get more than that, all the better. He's got a great deal of ability."
Tanaka went 24-0 with a 1.27 ERA in Japan last year. Cashman said it is asking too much of him to be a staff ace.
