Between the Majors and Minors, Laffey has logged 159 1/3 innings this season -- a significant increase over his 2011 total of 57. As a result, the lefty is feeling the general fatigue most pitchers experience at this time of the year, but manager John Farrell is not concerned and is encouraged by the progress that Laffey has made between starts.
"He felt a little soreness in his back that he is working through," Farrell said of Laffey. "He is gaining ground on that every day, and he's been able to play catch the last couple days and has felt good with it. We know where he is at physically at this time of year."
The 27-year-old Laffey has recorded the second-most innings of his career at the Major League level -- his high is 121 2/3 in 2009 as a member of the Indians -- and he takes a 4-6 record and 4.52 ERA into his final start.
Laffey signed a Minor League deal with the Blue Jays in September and began the season at Triple-A Las Vegas, where he went 3-5 with a 4.52 ERA over 11 starts.
