Mets RHP Noah Syndergaard limited the Orioles to one run on eight hits in seven innings on Sunday in Sarasota.
Syndergaard struck out five, did not walk a batter, and lowered his spring training ERA to 1.35 in what was his longest start of the spring.
"The slider felt nice coming out of my hand," Syndergaard told reporters after the game.
The 25-year-old is set to pitch for the Mets on opening day for the second consecutive season - the first pitcher to do so since Johan Santana in 2008-2010.
"I'm super jacked for it," Syndergaard said earlier in the week. "It's just a great feeling, second year, starting opening day and coming out of the gates hot."
Syndergaard went 1-2 with a 2.97 ERA in an injury-shortened 2017 campaign due to a partial tear in his right lat.
