MASN’s Dan Kolko reports that lefty Ross Detwiler, dealing with an ailing back, will be placed on the 15-day disabled list. Dan Haren, recovering from inflammation in his right shoulder, will be activated from the DL and start on Monday, taking Detwiler’s spot on the 25-man roster.
Detwiler had compiled a 4.04 ERA over 13 starts. He had previously missed time between mid-May and mid-June with a strained oblique. Haren, on the other hand, has had no success to speak of this season, sporting a 6.15 over 15 starts. Among starters with at least 80 innings pitched, Haren has by far the highest home run rate per nine innings at 2.09, besting second-place Jeremy Guthrie’s 1.68.
