Detroit Tigers catcher Dillon Dingler (knee) has left the Arizona Fall League. The 24-year-old is dealing with knee soreness, but the good news is that the tests came back negative. The expectation is that Dingler will be fully healthy for the beginning of spring training. He slashed .238/.333/.419 with 14 homers across 387 plate appearances in the minors last season. The hope is that Dingler can be the catcher of the future in Detroit.
