"We wrestle with trying to keep them long, ready to start a game," Collins said of such relievers as Matsuzaka and Carlos Torres, "yet using them as their versatility dictates in shorter roles."
Another closer candidate is Vic Black, the organization's primary contingency plan behind Bobby Parnell heading into Spring Training. But Black's struggles this spring resulted in a demotion to Triple-A Las Vegas, where he has succeeded despite significant wildness. Black is unscored upon in 7 1/3 innings for the 51s, but he has also walked seven batters.
Collins suggested that Black won't earn a callup until his control improves.
"We're keeping tabs on him," Collins said. "I look at those stats every day."
Eventually, prospects Rafael Montero and Jacob deGrom could also enter the ninth-inning shuffle, though the Mets hope it doesn't come to that any time soon. In a perfect world, Farnsworth will keep the job for as long as he is able at age 38. He is 1-for-1 in save opportunities since assuming closing duties last weekend.
