Nittoli signed a minor-league contract with the Yankees on Dec. 15.
The 31-year-old right-hander is expected to report to Triple-A Scranton/Wilkes-Barre to begin the 2022 season. Nittoli made his MLB debut for the Mariners last June, giving up two earned runs over a lone inning out of the bullpen before he was outrighted off the 40-man roster just over a month later.
