Texas still on the line at $24 mil a pop until 2020

The career of Texas Rangers designated hitter Prince Fielder is likely over, as he is medically disabled and doctors will not clear him to play, according to multiple reports.
Fielder, 32, hasn't played since July 19 after an MRI revealed a herniation of disks in his neck just above an area that was repaired two years ago.
According to Fox Sports, which first reported that Fielder would not play again, the slugger had season-ending neck surgery last month.
