But in this case, the problem is that Toronto's bullpen likely can't afford to lose both young right-handers. Drew Storen and Brett Cecil are proven late-inning commodities, but after that, there's a lot of uncertainty. Sanchez or Osuna would help solidify the back end of the 'pen.
Sanchez seems more prepared to start after pitching a combined 130 1/3 innings in 2014 and 109 1/3 last year. Osuna has never thrown more than 78 innings, and a transition to the rotation would result in a strict innings limit. If Osuna began the year as a starter, he would have to be shut down in the second half, whereas Sanchez might be ready to settle in for the long haul.
