MIAMI — Kyle Stowers hit a three-run homer and the Miami Marlins defeated the New York Yankees 7-3 on Sunday, completing their first-ever sweep of the Yankees in a series of three or more games.

The Marlins (55-55) reached .500 for the first time since April 15, when the team was 8-8. Since June 13, the Marlins are 30-14; that’s tied with the 2003 team for the most wins in a 44-game span in franchise history, according to ESPN Research.

The 2003 Marlins went on to beat the Yankees in the World Series in six games.

Marlins starter Edward Cabrera (5-5) pitched six innings of two-hit ball with seven strikeouts and one walk. His only blemish came against the first batter he faced. Trent Grisham drove Cabrera’s 98.1 mph four-seam fastball to right-center.

Miami rookie Jakob Marsee, who made his major league debut on Friday, was 2-for-4 and finished a single short of the cycle.

Stowers made it 6-1 when he connected on an 0-2 fastball from Brent Headrick, who entered in the fourth with two on after starter Luis Gil (0-1) was lifted 3⅓ innings into his season debut.

Gil, the reigning AL Rookie of the Year, struck out three and surrendered five runs and five hits while issuing four walks in his return from a high-grade lat strain. He threw 77 pitches.

Gil’s shaky debut comes at a rough point in the season for the Yankees, whose inconsistency has prompted a rash of criticism, the latest coming from former Yankees stars Derek Jeter and Alex Rodriguez on Fox’s pregame show Saturday night.

“They make way too many mistakes,” Jeter said. “Way too many mistakes, and you can’t get away with making that number of mistakes against great teams.”

Added Rodriguez: “Where’s the accountability?”

Boone addressed those criticisms before Sunday’s game, saying it comes with the territory of being the Yankees, but he added after the loss that it’s “gut check” time for his club.

New York’s weekend series at Miami included the Yankees blowing a six-run lead in a wild 13-12 loss on Friday, before a 2-0 loss on Saturday.

The Yankees had a seven-game lead in the AL East in late May. By July 2, the lead was gone and the Yankees have been looking up at Toronto in the division ever since. The red-hot Boston Red Sox, who were more than 10 games behind the Yankees about two months ago, have overtaken their rival for the second spot in the AL East and AL wild-card lead.

“It’s getting late,” Boone said. “And it’s certainly not too late for us. I am confident that we’re going to get it together. But that’s all it is right now is, you know, it’s empty until we start doing it.”
