VIDEO: Willson Contreras Demolishes 1st Inning Grand Slam Against White Sox SP Lucas Giolito

Well, that lead was short lived. Shortly after Leury García got things started for the White Sox with a solo blast off the very first pitch he saw from Jon Lester, Cubs catcher Willson Contreras did one better by launching a frozen rope of a grand slam over the left field wall to give the Cubbies a 4-1 first-inning lead over Lucas Giolito and Co. in the Crosstown Classic.

That one got out of Wrigley Field in a hurry. Also, peep that chest bump and fist pump as Contreras is rounding first base!

They might not admit it, but Contreras' raw emotion proves that the Windy City Showdown means a whole lot to the Cubs. You gotta love meaningful baseball being played in mid-June.
