Edwin Diaz injured his right leg as Puerto Rico celebrated its 5-2 victory over the Dominican Republic on Wednesday night to advance to the quarterfinals.

The Mets closer, who struck out the side and earned the save, appeared to hurt his knee as the team began celebrating.

Diaz had to be carried off the field and was eventually placed in a wheelchair.

After securing the final out, he was has embraced by some of his teammates and they began jumping up and down together.

This century, there have been, by my count, 20 contracts of four or five years handed to free-agent relievers, not counting the new deal for Díaz. Jansen, Chapman and B.J. Ryan received five-year deals, and the remainder were all for four years. One of the deals, Raisel Iglesias’, is still underway with 1.6 WAR in year one — although most of that came after the team that signed him, the Angels, dumped him and the contract on Atlanta midway through year one. Jansen’s and Chapman’s immediately followed the ends of those five-year periods I mentioned above.

Of the other 19, nine of them resulted in 4 WAR or less from the pitcher over the course of the deal, regardless of teams. That includes Brett Cecil (minus-0.5), Justin Speier (0.8), Drew Pomeranz (1.8, and out for all of year three due to injury), and Scott Linebrink (1.8). Only three of the deals resulted in an average WAR of at least 2: the Kimbrel deal originally signed with the Padres, the Miller deal with the Yankees and Mariano Rivera’s contract from 2001 to 2004. That Rivera deal is the only four- or five-year contract given to a reliever who produced at least 10 WAR over the course of the deal. One out of 19, and it belongs to the greatest short reliever the game has ever seen. Do you feel lucky? I sure don’t.
