The Blue Jays designated David Purcey for assignment, according to Shi Davidi of Sportsnet.ca (on Twitter). Toronto recalled Casey Janssen and Brad Mills and officially placed Rajai Davis on the disabled list in related moves.
Purcey faced four batters in last night's ugly loss to the Mariners, allowing two hits and a walk. Though Purcey entered the game with the Blue Jays leading 7-1, the Mariners scored five runs in the eighth because of his poor performance and bases loaded walks by Octavio Dotel and Marc Rzepczynski. The Mariners completed the improbable comeback to win 8-7.
In five outings this year, Purcey has an 11.57 ERA with three strikeouts and four walks in 2 1/3 innings. The left-hander was considerably more effective in 2010, when he posted a 3.71 ERA with 8.5 K/9 and 4.0 BB/9 in 34 innings. The 28-year-old went 16th overall in the 2004 draft.
