The Royals announced that they have claimed left-hander Tyler Olson off waivers from the Yankees and optioned him to Triple-A Omaha. In order to clear a spot on the 40-man roster for Olson, who had previously been designated for assignment by the Yankees, the Royals have transferred third baseman Mike Moustakas to the 60-day disabled list. (Moustakas is out for the season due to a torn ACL.)
The 26-year-old Olson pitched just 2 2/3 innings for the Yankees this season and struggled, as he’s done in his 27 1/3 innings with Triple-A Scranton/Wilkes-Barre this season. He’s had an active calendar year on the waiver wire, beginning with the Mariners before being picked up by the Dodgers and then the Yankees prior to today’s move. Olson has a 4.74 ERA with 8.2 K/9 against 2.8 BB/9 in 81 2/3 innings at the Triple-A level in his career. The 2013 seventh-round pick out of Gonzaga began his pro career as a starter but was shifted primarily to the bullpen with the Mariners last season. He’s made three starts and eight relief appearances with the Yankees’ top minor league affiliate this year.
