WRIGLEYVILLE — Put the brooms away. The Cubs aren't dead yet.

Behind the strength of former Cy Young winner Jake Arrieta and slugging second baseman Javier Baez, the Cubs won Game 4 of the National League Championship Series Wednesday, denying the Los Angeles Dodgers a chance to sweep the series.

The series is now 3-1 in favor of the Dodgers, with Game 5 scheduled for Wrigley Field Thursday night.

Arrieta, the righty who might have pitched his last game as a Cub before he enters free agency, kept the Dodgers down with a solid start. And Baez, who didn't have a hit in this postseason, banged two home runs into the left field bleachers.

Cubs fans who swarmed Wrigleyville on Wednesday collectively held their breath as the North Siders held on for victory.

"It's more relief tonight than anything else," longtime Cubs fan George Deis said. "There's no other place to be in October."

Leslie Lapthorne and Ian Wexell, lifelong Cubs fans who are engaged, said they have faith the Cubs will pull through and come out on top by the end of the series.

"Today was a must-win, and we won it," Lapthorne said. "It's just one game at a time.

"We've been down 3-1 before," Wexell added. "This is familiar territory, and we know we can do it. We'll be back here for Game 7 and through all the World Series."

Lapthorne added experiencing the postseason in Wrigley is "surreal."

"Last year we went to a few rooftop games, and this year we went to an NLDS game," she said. "And even if you're not at the game, just being around here, it's playoff baseball at Wrigley, what more do you want? I can't believe we're doing it again. It seems like it just happened."

Game 5 will begin at 7:08 p.m. Thursday, and, if necessary, the Cubs will travel to Dodger Stadium for Games 6 at 3:08 p.m. Saturday and Game 7 at 7:38 p.m. Sunday. All games will be airing on TBS, and Chicago fans can watch the away games at the Park at Wrigley for $10.
