NEW YORK -- Rookie Gary Sanchez homered for the eighth time in nine games and drove in four runs as the New York Yankees beat the Baltimore Orioles 14-4 Friday night in the opener of their weekend series.
Sanchez, who had three hits, had a two-out single in the bottom of the first. Teixeira followed with a towering shot into the right-field bleachers off Yovani Gallardo to give New York a 2-1 lead.
The Yankees broke the game open against Gallardo (4-6) with a six-run second. The right-hander was charged with eight runs over 1 1/3 innings, the shortest start of his 10-year career.
Luis Cessa (4-0) gave up three runs and five hits over six innings in his second big-league start.
Manny Machado homered twice for the Orioles, giving him 31 for the season. Along with Mark Trumbo (38) and Chris Davis (30), it marks the first time in franchise history the Orioles have three players with 30 homers before September.
Headley singled and Aaron Judge walked to start the second inning. Ronald Torreyes lifted a fly ball to left-center field but a charging Nolan Reimold could not glove the ball cleanly, loading the bases. Reimold had just replaced star center fielder Adam Jones, who exited with a left hamstring strain.
Sanchez, hitting .541 with eight homers and 14 RBI over his last 10 games, chased Gallardo with a two-run double to right that made it 7-1.
Teixiera capped the scoring in the big inning with an RBI single off reliever Vance Worley for his third RBI of the game.
Headley's two-run homer in the fourth pushed the Yankees lead to 10-1, and Sanchez clubbed a two-run shot in the next inning for his 10th homer in 20 games this season.
Machado, who gave the Orioles the lead in the first, hit his second of the game into the right-field seats in the sixth to make it 12-3 with his ninth career multi-homer game.
Torreyes and Gardner both had RBI hits in the seventh.
Yankees right-hander Ben Heller pitched a scoreless eighth in his major league debut.
Orioles: Jones was in the starting lineup despite leaving Thursday night's game with hamstring cramps. He hustled down the line but was thrown out on a soft grounder to third in his only at-bat. ... RHP Chris Tillman (right shoulder bursitis) is scheduled to throw on flat ground Tuesday.
Yankees: C Brian McCann was not with the team due to the death of his grandmother. ... RHP Bryan Mitchell (toe tear on left foot), reinstated from the 60-day disabled list and optioned to Triple-A on Wednesday, could pitch for the Yankees this season. "I think it's a distinct possibility," manager Joe Girardi said.
Orioles: Rookie RHP Dylan Bundy (7-4, 3.33 ERA) attempts to win for the fifth time this month.
Yankees: RHP Chad Green (2-3, 3.66 ERA) has struck out 16 batters in 12 innings over his last two starts, allowing just one run over that span.
