Vientos could serve as the Mets' starter at designated hitter to begin the season if J.D. Martinez agrees to be optioned to Triple-A Syracuse, Tim Healey of Newsday reports.
Martinez would need to consent to being optioned since he's accrued so much service time, but it sounds like he would be willing to do so in an effort to get up to game speed as quickly as possible. The move would allow Vientos at least a short-term run of everyday playing time. When Martinez is deemed ready, Vientos could be looking at a short-side platoon role at third base or a trip back to Syracuse.
