Steven Matz Put on 10-Day DL by Mets with Forearm Injury; Corey Oswalt Recalled

The New York Mets announced starting pitcher Steven Matz was placed on the 10-day disabled list Friday because of a flexor pronator strain in his left arm. 

New York recalled starter Corey Oswalt to fill the void on the 25-man roster.

Matz alerted the organization about forearm tightness after allowing seven earned runs on eight hits and one walk in two-thirds of an inning as part of a 25-4 loss to the Washington Nationals on Tuesday night, per Anthony DiComo of MLB.com.

"There's a good chance we just take a conservative approach here," Mets assistant general manager John Ricco said. "It's the middle of a long season."

The 27-year-old left-hander has posted a 4.35 ERA and 1.34 WHIP with 99 strikeouts in 107.2 innings across 21 starts so far this season. He finished the 2017 campaign with a 6.08 ERA in 13 outings and owns a 4.10 career ERA across four years.

He joins Yoenis Cespedes, Jay Bruce and David Wright on the Mets' star-studded DL. Fellow starters Jacob deGrom and Noah Syndergaard have also missed time because of injuries this season.

Oswalt has made six appearances (five starts) while filling in for New York in 2018. While his ERA stands at 5.27, his 0.98 WHIP suggests he's pitched better than his ERA indicates.

The injury issues are one reason the Mets have started to fade from the playoff race with a 44-62 record.
