Three calls overturned in Astros-White Sox tilt

Porter wins pair of challenges; Ventura gets out at first reversed

CHICAGO -- Baseball's replay system got a workout Saturday night at U.S. Cellular Field. 

The Astros were trying to get out of a third-inning jam when a challenge by manager Bo Porter overturned a call that would've loaded the bases with one out.

The initial call by home plate umpire Brian O'Nora -- after a lengthy chat with White Sox manager Robin Ventura and then fellow umpires -- was that Gordon Beckham was hit by a pitch in his lower left ankle. After a three-minute and 49-second delay, it was ruled that the ball did not hit Beckham.

Astros pitcher Dallas Keuchel struck out Beckham on the next pitch. He then walked Alejandro De Aza to load the bases and hit Tyler Flowers with a pitch to force in a run and give the White Sox a 3-0 lead. Keuchel struck out Adam Eaton looking a batter later to end the inning.

In the fourth, Ventura successfully challenged a call at first base. Alexei Ramirez was originally ruled out by first-base umpire Marcus Pattillo, but replays showed Ramirez beat third baseman Matt Dominguez's throw. 

Later in the inning, Porter challenged a safe ruling at second base, and replays overturned D.J. Reyburn's original ruling after one minute and 12 seconds.
