An unfulfilling off-season and an ill-timed injury to Martin Perez (he'll miss all of April after being hit by a line drive in a spring game) left the Rangers scrambling to fill the back of their rotation. They smartly decided against signing free agent Kyle Lohse (who joined the Brewers on Monday), allowing them to keep their first-round pick in this year's draft. A better option: The team should use starters turned relievers Robbie Ross and Tanner Scheppers as tandem starters until Perez returns—one starts, one quickly relieves, every fifth day. Neither Ross, a lefty, nor Scheppers, a righty, will be ready to be a traditional starter by Opening Day, but each could go three innings at a clip. This is a popular strategy in the low minors; in the majors it would allow the Rangers to exploit unbalanced lineups with an early-game pitching change and keep both pitchers from working while fatigued. All of the above should lead to better run prevention than some off-the-scrap-heap fifth starter.
