Estrada and Mike Fiers are both being considered to take Matt Garza's spot in the rotation, Todd Rosiak of the Milwaukee Journal Sentinel reports. Garza was forced on the DL on Tuesday with a left oblique strain, opening the door for either Estrada or Fiers to step into the rotation starting Saturday. Estrada's struggles with the long ball this season are well-documented -- he's given up 27 homers in 117.1 innings -- and Fiers has fared well in 17 starts for Triple-A Nashville (2.55 ERA, 0.94 WHIP), so it wouldn't be a surprise to see Fiers get the nod.
