The Rangers have designated left-hander Zach Phillips for assignment, reports Jeff Wilson of the Fort Worth Star-Telegram. The move creates a spot on the 40-man roster for Scott Feldman, who was activated from the 60-day DL and cleared outright waivers earlier today. In another corresponding move, the Rangers optioned Darren O'Day to Triple-A in order to make room for Feldman on the 25-man roster.
Phillips, 24, was taken by the Rangers in the 23rd round of the 2004 amateur draft. He began his pro career as a starter but has primarily been used as a reliever for the last three seasons. Phillips has a career 4.10 ERA, an 8.6 K/9 rate and a 2.33 K/BB ratio in 213 minor league appearances, 98 of them starts.
