Gregorius, who turns 30 in February, came back from Tommy John surgery in early June and hit .238 with 16 homers and 61 RBIs in 82 games.
Tyler Lyons, who earned a spot on the Yankees' postseason roster as a left-handed reliever, refused an outright assignment to Triple-A Scranton/Wilkes-Barre and elected to become a free agent.
The 31-year-old was released by Pittsburgh in August and signed with New York. He struck out 12 and walked two in 8 2/3 innings during 11 appearances with the Yankees in September. He made one appearance each in the Division Series against Minnesota and the Championship Series vs. Houston, striking out four over 1 2/3 hitless innings.
New York reinstated third baseman Miguel Andujar, first baseman Greg Bird, right-handers Jonathan Holder and Jake Barrett and outfielder Jacoby Ellsbury from the 60-day injured list and assigned Barrett outright to Scranton/Wilkes-Barre.
Ellsbury has not played since 2017 because of a variety of ailments. He is owed $21,142,857 next year in the final guaranteed season of a $153 million, seven-year contract, which includes a $5 million buyout of a $21 million option for 2021.
