Shelby Miller's season could be over early for the second year in a row.

The Arizona Diamondbacks earlier this week shifted the 27-year-old Brownwood High School graduate from the 10-day disabled list to the 60-day disabled list. Miller was originally placed on the 10-day disabled list on July 12 due to inflammation in his right elbow following his fourth start in his comeback from Tommy John surgery a year ago.

An MRI revealed no further UCL damage, but speculation is Miller may not pitch again this season as he is not eligible to return to the active roster until Sept. 11.

Posting an 0-4 record with an 11.40 ERA in four starts for Arizona this season, further speculation indicated Miller might be moved to the bullpen upon his return. That, however, was before Miller's DL stay was extended.

For his career, Miller owns a 37-53 record with a 3.84 ERA in 130 games, including 124 starts. Miller has recorded 592 strikeouts in 713.1 innings pitcher.

Prior to Thursday's action, the Diamondbacks (60-49), winners of seven of their last 10 games, were tied with the Los Angeles Dodgers (60-49) for first place in the National League West division.
