LOS ANGELES -- The longest postseason run-scoring drought in Cubs history has come to a close. Willson Contreras singled home Ben Zobrist with no outs in the top of the fourth inning to finally break his team through.

The last run the Cubs had scored before that was Dexter Fowler's home run in the bottom of the eighth inning all the way back in Game 1.

So with shutouts in Games 2 and 3 and going scoreless through the first three innings on Wednesday in Game 4, that was a 21-inning drought without runs.

This one was setup by a Ben Zobrist bunt for a hit and then a Javier Baez single. Contreras followed with the single.

The next run didn't have to wait long. The runners had advanced to second and third on an errant throw home by left fielder Andrew Toles, so Jason Heyward's ground out made it 2-0 Cubs.

And then, Addison Russell came through with a two-run homer, making it 4-0 Cubs.

Maybe they just needed to get a run across the board and relax. We'll see how the rest of the game goes.
