The Hanshin Tigers may still be the best team in the Central League, but they are no longer undefeated.

Yakult first baseman Roberto Petagine belted a grand slam in the seventh inning as the Swallows rallied to beat the Tigers 5-3 Sunday afternoon at Jingu Stadium.

It was the first defeat for the Tigers, who opened the season with seven straight wins, matching their 64-year-old franchise record.
