Those champagne corks won’t be popped until Sunday at the earliest.

The Philadelphia Union defeated the San Jose Earthquakes, 2-1, in San Jose, Calif. Wednesday night, delaying New York City FC’s hopes of clinching the MLS Eastern Conference crown.

City is a point away from clinching its first conference title in the club’s five-year history after trouncing defending MLS Cup champion Atlanta United, 4-1, at Yankee Stadium earlier in the evening.

NYCFC, which needs a point to clinch or Philly to drop a point, visits the New England Revolution Sunday, while the Union plays at Columbus Crew SC.

On Wednesday night, Philly secured its victory 16th of the season, setting a club record for most wins in a season that beat out the 2017 season’s 15 triumphs.

Kacper Przybylko scored his team-leading 15th goal of the season, passing Sebastien Le Toux for second on the Union’s all-time goals scored list.

Team captain Alejandro Bedoya tallied his fourth goal of the season, a personal best while with Philadelphia.
