Mets reliever Grant Hartwig underwent surgery to repair a meniscus tear in his left knee, the team announced, via Tim Healey of Newsday. He’ll be out for six to eight weeks.
Hartwig, 26, is a depth arm who has pitched for the Mets in each of the last two seasons. He made 28 appearances as a rookie, working to a 4.84 ERA across 35 1/3 innings. That was enough for Hartwig to hang onto his spot on the 40-man roster throughout the offseason. He has pitched in four big league games this year, allowing six runs over 6 2/3 frames.
New York has kept Hartwig on optional assignment to Triple-A Syracuse for the majority of this season. The righty has turned in a 2.31 earned run average in 23 1/3 innings there. Hartwig has an average 22.3% strikeout rate against a lofty 11.7% walk percentage. He’ll continue to count against the 40-man roster while he’s on the minor league injured list.
