The Yankees traded RHP Nick Rumbelow in exchange for minor league pitchers JP Sears and Juan Then.
Sears, 21, made 17 relief appearances in Single-A ball last season and posted a 0.65 ERA. In 27.2 innings of work, he struck out 51 batters. Then, 17, went 2-2 with a 2.64 ERA in 13 Rookie League games in 2017. He struck out 56 batters in 61.1 innings.
Rumbelow split time between Triple-A Scranton and Double-A Trenton last season, going 14-8 with a 2.73 ERA. His lone stint in the majors came in 2015 when he played in 17 games for the Yankees.
The Yankees have until Monday to assign players to their 40-man roster.
