Lackey will start Friday against the Reds, Jim Bowden of ESPN.com reports. Lackey's frustration seemed to boiled over his last time out, as he was ejected for arguing balls and strikes after giving up two runs in just two innings against Cincinnati. Sensing he could use a breather, manager Mike Matheny decided to skip Lackey one time through the rotation, but he'll return to oppose David Holmberg in Friday's series opener.
