New York Mets 
On April 23, 2012, Hefner was called up to the Mets roster to fill in for Ronny Cedeño, who was placed on the disabled list with a strained left intercostal muscle. He pitched three scoreless innings, allowing three hits and one walk. He was sent down to Buffalo after the game, which the Mets lost to the San Francisco Giants, 6–1. Hefner recorded his first career loss against the Toronto Blue Jays on May 19, 2012, after pitching 5 innings of relief.
On May 24th, Hefner made his first MLB start against the San Diego Padres. Then on May 30, Hefner recorded his first big-league win against the Philadelphia Phillies, which also included his first hit, a home run. He was the first pitcher to homer in the same game he got his first big-league win since Dennis Tankersley did it on May 26th, 2002. He was also the first Mets pitcher to get his first win and homer on the same day.
On July 4, 2012, Hefner was optioned to triple-A Buffalo. However, he was called back on July 21, after an injury to Johan Santana. On August 26th, Hefner pitched his first game since returning from paternity leave for the birth of his second child. Although he got a no-decision Hefner pitched the best game of his rookie season by going 8 innings and only surrendering 1 run on 5 hits.
On Sept. 26, 2012, Hefner was the winning pitcher on the same night that David Wright broke the Met's all time hit record. 
Pitching style 
Hefner throws five pitches. He leads with a four-seam fastball around 89–91 mph. He also throws a two-seam fastball (89–91), a slider (86–89), a curveball (74–77), and a changeup (83–85). Right-handed hitters see a higher number of sliders, but he mixes all of his pitches against right-handed and left-handed hitters. Hefner's pitches have below-average whiff rates, reflected in only 18 strikeouts in his first 32 innings of work. However, he has also shown excellent control, walking only four batters in that span.
