Things got testy when Manny Machado hustled down the first-base line in the 10th inning Tuesday night in Game 4 of the National League Championship Series at Dodger Stadium. Machado hit a routine ground ball to Brewers shortstop Orlando Arcia, who made an easy throw to first base for the inning's second out. But Machado clipped Aguilar's back leg with his left foot as he crossed the base. Aguilar hobbled away and Machado and Aguilar shortly thereafter exchanged words.
