Rodriguez has not played in a game since September 2013 after serving a season-long suspension in 2014 over infractions related to performance-enhancing drugs, including his involvement in the Biogenesis scandal. He admitted to taking PEDs in January 2014.
"I think I'll be fine," Rodriguez said, according to the report. "Only time will tell."
Rodriguez reported to spring training camp on Monday, two days earlier than position players were expected to show up.
Rodriguez, 39, is entering his 11th season with the Yankees. He has three years and $61 million remaining on his contract.
