Right-hander Ryne Stanek relieved David Peterson and served up a two-run home run to Orioles’ Gunnar Henderson, overtaking the Mets for a 2-1 win.

BALTIMORE — Gunnar Henderson hit a two-run drive in the eighth inning for his first career pinch-hit homer, and the Baltimore Orioles beat the New York Mets 3-1 in the opener of a doubleheader on Thursday.

The series is now tied at one game apiece following Baltimore’s late rally for a 3-1 win. Gunner Henderson came off the bench and stroked a two-run pinch hit home run in the bottom of the eighth to propel the O’s to the win. David Peterson (7IP, 1ER) and Charlie Morton (6IP, 1ER) engaged in a pitchers’ duel until Henderson’s heroics.

During the fourth inning of Thursday afternoon's Game 1, Hernandez made it clear that—despite essentially being forced into calling two games in one day—he'll still only be working his allotted assignment for the season. "They have to lop one off on me," said Hernandez. "I only do 110. So, this is one I wasn't supposed to do."

The New York Mets could be on the hunt for relief pitching this season, which might turn them to the Baltimore Orioles to poach a flamethrower.

The Mets aren’t alone in trying to ensure their pitchers get the right amount of work before the four-day break, but a Thursday doubleheader will make that more complicated.

Jesse Winker may need another trip to the IL after his back locked up in Baltimore, which could open the door for Drew Gilbert's big league debut with the Mets.

It’s 28-year-old Justin Hagenman the Mets are expected to look toward in Thursday’s doubleheader nightcap – provided he isn’t needed from the bullpen in the opening game.
