Yankees reliever Dellin Betances delivered the defining moment of last week’s Subway Series between the Yankees and Mets.

In Thursday’s affair, with the fate of the game in flux, Betances not only pitched 2.1 innings of perfect baseball, but he also struck out six straight batters over the sixth and seventh innings. He impressed many with his 97-mph fastball, but it was his 82-mph knuckle-curve that forced Mets broadcaster Keith Hernandez to emit a deep “Mmmm” after every pitch.

Take a look at Betances’s final pitch of the evening, getting Ruben Tejada looking on a nasty hook:

Betances has had a long road to the Yankees’ 2014 bullpen. After getting drafted in 2006 out of Grand Street Campus High School in Brooklyn, N.Y., he battled both injuries and his command in the minor leagues. Now he’s posting a K/9 of 15.53 and a 1.26 FIP this year, turning heads with his blazing fastball and tight knuckle-curve.

Many are speculating that Betances will be the Yankees’ future closer, as David Robertson will be a free agent after this season. After taking just one look at today’s GIF, it’s easy to see why.
