Mets left-hander Steven Matz has been named National League Rookie of the Month for May.

The 25-year-old went 4-0 with a 1.83 ERA in five May starts, striking out 31 batters in 34 1/3 inning while issuing just four walks.

Matz ranked fifth among all NL pitchers in ERA on the month, while his 0.76 WHIP was second only to the Dodgers' Clayton Kershaw.
