I'd like to see the Mets make a run at 24-year-old Cuban RHP Yaisel Sierra, who is currently considered the top unrestricted free agent from Cuba.
According to MLB.com's Jesse Sanchez, Sierra's fastball is consistently in the 94-97-mph range, "and he hit 98 mph in a showcase in front of 100 scouts in August in the Dominican Republic."
Sierra has been throwing for teams each week for the past two months in the Dominican Republic, according to Sanchez.
Sierra is not subject to the international signing guidelines, because of his age and experience. It's possible Sierra could help a Major League team next season, scouts recently told Sanchez, who feels he could eventually be a top of the rotation starting pitcher. In the meantime, scouts say he could easily adjust to being a reliever and possible closer.
The word from scouts is that he has a hard fastball, a nice slider, easy, traditional motion, the occasional three-quarter arm slot and typical command issues. However, they say with a little refinement in the minor leagues, and adding a change up, he could become a legit bullpen arm for a team late next season. He's going to see a lot of interest when his market opens because he's outside the bonus pool.
The sense I get is that Sierra will cost a five- to seven-year deal, somewhere around $4-5 million a season. He is not yet cleared to sign with an MLB team. However, when he is, the Mets should make a move to acquire him. They never take these sort of chances. In this case, Sierra may be worth the risk, because of his age, position, velocity and reasonable contract.
