The Blue Jays have issued a press release to announce a series of roster moves: Right-hander Marcus Walden has been designated for assignment in order to clear a 40-man roster spot for Munenori Kawasaki, who has been promoted to the Majors to take the 25-man roster spot of Maicer Izturis. Izturis, who is most likely out four to six months with a torn LCL, has been placed on the 15-day DL. Additionally, the club announced that right-hander Jeremy Jeffress, who was designated for assignment last week, has cleared waivers and been outrighted to Triple-A Buffalo.

Walden, who turned 25 near the end of the 2013 season, began the year at Buffalo but pitched just four innings prior to today's news. The former ninth-round pick allowed six runs in those four frames but posted a strong 3.71 ERA in 162 1/3 innings at Double-A New Hampshire in 2013. Walden misses few bats but has solid command, as evidenced by career ratios of 5.4 K/9 and 2.9 BB/9 in his minor league career.

The 32-year-old Kawasaki appeared in 96 games for the Blue Jays last season, quickly winning over fans and teammates with his quirky personality and his sense of humor. On the field, he batted .229/.326/.308 with a homer and seven stolen bases while appearing at both middle infield positions.

Jeffress has seen MLB time in five seasons, but has never logged more than 15 1/3 innings in any one season. The former No. 16 overall pick (Brewers) has yet to harness his big arm, as his career 6.7 BB/9 tally in the bigs would indicate. He did put up outstanding results last year, as he yielded one earned run with a 12-to-5 K:BB ratio in 10 1/3 Major League innings in addition to registering a 1.39 mark in his 32 1/3 minor league innings (8.4 K/9 against 3.6 BB/9).
