2. Extra rest. As Jon Meoli pointed out in this morning's paper, the Orioles' move to a six-man rotation has earned mixed reviews and results from the starting staff. Chris Tillman, today's starter, has been one who has been hurt the most by it. He hasn't pitched well in any circumstances this season, but his ERA on regular rest is 6.69 while his ERA with extra rest is 9.73. Today he pitches on five days' rest after allowing 10 runs in 10 1/3 innings in his first two games back to starting.
