Ottavino struck out 112 batters in 77 2/3 innings in 2018.
Ottavino has spent the last seven seasons with the Rockies. He had a career year in 2018 and ended last season with a 2.43 ERA while striking out 112 batters in 77 2/3 innings. His previous season-high in strikeouts was 81.
New York ranked No. 4 in reliever ERA in 2018 at 3.38. Yankees relievers fanned 753 batters in 594 2/3 innings, which was the second-most strikeouts of any bullpen.
The Yankees lost reliever David Robertson to the Phillies on Jan. 3. Ottavino is expected to fill Robertson's role as a right-handed bullpen arm. He will likely work as a setup man or middle reliever in front of closer Aroldis Chapman.
