SAN DIEGO — Yu Darvish had his best outing since being sidelined for more than three months, and rookie Jackson Merrill and Jurickson Profar homered as the San Diego Padres beat the Houston Astros 3-1 on Monday night.
The Padres took a 2 1/2-game lead over Arizona for the top NL wild card and stayed 3 1/2 games behind the first-place Los Angeles Dodgers in the NL West.
Houston's lead in the AL West dropped to four games over idle Seattle.
Padres leadoff hitter Luis Arraez struck out for the first time since Aug. 10, snapping a streak of 141 plate appearances without whiffing. He went down swinging against rookie Spencer Arrighetti to end the second inning.
It tied Padres Hall of Famer Tony Gwynn for the fifth-longest streak in the last 40 seasons. Gwynn, who played his entire career with the Padres, had the longest such streak, 170 plate appearances in 1995.
Arraez, the DH, later left the game with a knee injury. He was shaken up on a slide as he was tagged out at home plate in the fifth. Arraez initially stayed in the game and doubled in the seventh, but walked off the field gingerly after being replaced by pinch-runner Tyler Wade.
''He jammed his knee in the plate,'' manager Mike Shildt said. ''Reports are stable, sore. You could tell after he legged out the double.''
''What a gamer,'' said Shildt, who added that Arraez told him before his at-bat in the seventh, ''`I can hit.'''
