CINCINNATI -- The Cubs challenged a call at first base in the fifth inning, and it was overturned.
With Cincinnati leading, 6-2, Kris Negron led off the Reds' fifth by hitting the ball toward first baseman Chris Valaika, who flipped to pitcher Carlos Villanueva. First-base umpire Ben May ruled Negron was safe with an infield hit.
But Cubs manager Rick Renteria challenged the call, and after a 44-second review, it was overturned.
The Cubs now have challenged 48 calls this season, and won 20.
