Matz, a 24-year-old left-hander who is the team’s top overall prospect, was informed of his promotion on Thursday and should make his debut sometime this weekend against the Cincinnati Reds.
The Mets also plan on going back to a six-man rotation, a system they employed earlier in the season. The plan was scrapped when the team sent Dillon Gee to the bullpen.
Gee was soon designated for assignment and is now pitching for Triple A Las Vegas.
Matz had a 7-4 mark with a 2.19 ERA and 90 strikeouts in 90 1/3 innings with Las Vegas this season.
Matz now joins a rotation featuring Jonathon Niese (3-7, 4.12 ERA), Jacob deGrom (8-5, 2.15 ERA), Matt Harvey (7-5, 3.18 ERA), Noah Syndergaard (2-4, 4.03 ERA) and veteran Bartolo Colon (9-6, 4.89 ERA).
New York (37-37) has lost seven of its last eight games. The team has scored four runs or more only three times in its last 14 contests.
The Mets are 3.5 games behind the Washington Nationals in the National League East.
