Yankees Designate Tyler Olson, Select Anthony Swarzak

The Yankees have designated lefty Tyler Olson for assignment, per a team announcement. The club selected the contract of righty Anthony Swarzak, who takes Olson’s 40-man slot, and optioned fellow righty Luis Cessa to open an active roster spot.

The 30-year-old Swarzak returned to American ball on a minor league pact with the Yankees after spending the bulk of 2015 pitching for Korea’s Doosan Bears. He’s a veteran of six big league seasons, all of which have come with the Twins with the exception of 2015, which he began with the Indians and finished in Korea. Swarzak, a former second-round pick and well-regarded prospect, never established himself as the starter Minnesota had hoped when Baseball America rated him as the game’s No. 100 overall prospect prior to the 2006 season. However, he did settle in as a useful long reliever/spot starter for the Twins for a few seasons, working to a 4.21 ERA with 5.5 K/9 against 2.5 BB/9 in 380 2/3 innings from 2011-14. His best season was a 2013 campaign that saw him post a 2.91 ERA in 96 1/3 innings for Minnesota.

Olson, 26, worked 2 2/3 innings for the Yankees this season and allowed a pair of earned runs. He’s also recorded 27 1/3 innings at the Triple-A level, though his 5.27 ERA there is lackluster as well. New York acquired Olson from the Dodgers alongside Ronald Torreyes this offseason, but he’ll now be faced with his third DFA since the end of the 2015 campaign. The former seventh-rounder has a 3.99 career ERA in the minors.
