BALTIMORE (AP) — Gunnar Henderson led off the first inning with a homer to become the youngest player in major league history with 10 before May 1 and the Baltimore Orioles defeated the New York Yankees 2-0 on Monday night in the opener of a four-game series.

Grayson Rodriguez threw 5 2/3 shutout innings for Baltimore, which won the first meeting of the season between the top two teams in the AL East.

After fouling off the previous three pitches, the 22-year-old Henderson lined a 2-2 knuckle-curve over the wall in right off Clarke Schmidt (2-1). Henderson tied the Los Angeles Angels’ Mike Trout for the major league lead in homers.

Henderson’s ninth homer of the month tied him with Chris Davis (2013) and Manny Machado (2018) for the third most in April in Orioles history. Brady Anderson hit 11 in 1996 and Frank Robinson had 10 in 1969.
