The best relief pitcher available this offseason just might be a guy who pitched to exactly two Major League hitters in 2019.

This was a lost year for Dellin Betances — hardly the sort that a pending free agent desires.

A right shoulder injury held the 6-foot-8 right-hander out until Sept. 15, when a left Achilles injury turned his season debut into his season finale.

It might prove to have been Betances’ Yankees finale as well. An eighth-round pick by the team in the 2006 Draft out of a Brooklyn high school, Betances has spent his entire career in pinstripes but now finds himself on the open market as he heads toward his age-32 season.

Despite the less-than-ideal circumstances, Betances still should do quite well this winter, perhaps in the form of a one-year deal that would give him a chance to take another crack at free agency in 2020-21. The fact that the Achilles injury didn’t require surgery should help, along with the news that, per SNY’s Andy Martino, Betances is expected to be “fully recovered” by December.
