    Justin Martinez' Split Finger Could Make Him an Elite Closer Someday

    During Friday night's 4-2 loss to the Baltimore Orioles, the biggest highlight for the Diamondbacks might have been the appearance by Justin Martinez. Martinez did all this plowing through the middle of the order of the best offense in the American League. Four of the five strikeouts came on swing and miss from his splitter. Martinez averages 100 MPH on both his four seam fastball and sinker and can top out at 102 MPH.
