New York Mets star Jacob deGrom secured back-to-back National League Cy Young Award honours, while Houston Astros ace Justin Verlander was also recognised again in the American League.

MLB's biggest pitching prize was announced on Wednesday, with DeGrom topping the votes in the NL and Verlander in the AL midweek.

DeGrom became the 11th pitcher to secure successive Cy Young Awards after appearing at the top of all but one of the 30 ballots this year.

"Words can't express it," DeGrom said. "I said it was a dream to win one, but to win back to back, honestly, I'm kind of speechless right now."

A three-time All-Star, DeGrom had a 1.89 ERA and .538 opponents' OPS in his final 23 starts, covering 152 innings, as the Mets missed the playoffs for the third consecutive season.

DeGrom led the NL in strikeouts (255) and ranked second in ERA (2.43) after the Mets posted a 77-85 win-loss record in 2019.

As for Houston's Verlander, the eight-time All-Star finally added to his 2011 AL Cy Young Award.

Verlander produced one of his best seasons as the Astros reached the World Series before falling to the Washington Nationals – leading the league in wins (21), innings (223), batting average against (.172) and WHIP (0.80).

The 36-year-old finished ahead of Astros team-mate Gerrit Cole, who has been linked with a move away from Houston.
