Watch: Moncada follows game-tying HR with 1st career walk-off hit

The Yoan Moncada era on the South Side is off to a pretty good start.

Moncada put the Chicago White Sox on his back Thursday night when his team needed him the most. With the White Sox trailing the Houston Astros 2-1 in the ninth inning, the 22-year-old clubbed a game-tying, opposite-field home run off Astros closer Ken Giles to electrify the Guaranteed Rate Field crowd.

But he wasn't close to done. In the bottom of the 11th, Moncada stepped to the plate and ripped a single through the right side of the infield. That scored Leury Garcia from second base, giving the basement-dwelling White Sox a 3-2 win - and completing a three-game sweep of the AL-best Astros, who are now in a 3-7 slide over their last 10 games.

Moncada - at 22 years and 75 days old - is the youngest White Sox player to record a walk-off hit since his fellow Cuban Dayan Viciedo did it in 2010 at the age of 21 years and 202 days, per CSN Chicago's Christopher Kamka.

Moncada has been on an absolute tear to begin the month of August. He's now hitting .391/.567/.565 with three RBIs, four runs scored, eight walks, and two extra-base hits in his last seven games.
