With Jon Gray hurt, the Rockies have a few interesting candidates for their rotation

German Marquez 

German Marquez is an attractive candidate for the job. Marquez made the professional roster out of Spring Training as a long-reliever, but with Chris Rusin returning from injury to occupy the role, Marquez was optioned to Triple-A.

Having bounced around between the minors and the majors, Marquez is one of the more intriguing options to take over as Gray returns from injury. His familiarity with both pitching as a starter and reliever for the Rockies should only help his case as decision looms.

Marquez has logged over 400 innings in his minor career, posting a record of 25-33 with an ERA of 3.61 and a WHIP of 1.23.

Still just 22-years-old, the organization thinks Marquez can and will be a starter for the club long-term. Now may be the best time for Marquez to get his feet wet with starting games at the Major League level for the Rockies in anticipation for what the future potentially holds.
