The Yankees continued to add depth to the back of their roster on Tuesday when they acquired lefthander Tyler Olson and infielder Ronald Torreyes from the Dodgers for minor-league infielder Rob Segedin and a player to be named or cash.

Olson and Torreyes both made their major-league debuts last season. Olson, 26, went 1-1 with a 5,40 ERA in 11 relief appearances for Seattle before getting traded to the Dodgers on Dec. 18.

Torreyes, 23, went 2-for-6 in eight games with the Dodgers. The righthanded hitter is primarily a middle infielder but has also seen time at third base and in the outfield.

Segedin, 27, hit .287 combined in Triple-A and Double-A last season.

The Yankees’ 40-man roster is now full.
