CHICAGO This was the moment Mary Gerrity had waited for her entire life.She loves the Cubs. A lifelong Chicagoan, she’s always loved the Cubs.And in the moments after her Cubs clinched their first trip to the World Series since 1945 a few years after she was born Mary was standing on top of the Wrigley Field dugout as the players rushed the field and the fans in the stands went crazy. She was in her baseball heaven.See, Mary’s an usher at Wrigley. If you’ve been there,you know the ushers are the lifeblood of this historic Keith Hernandez Jersey stadium. It’s not a job so much as it is a calling. The players who wear the uniform measure their time with the club in years. Ushers here measure their time in decades.MORE: Must-see NLCS photosIf you haven’t been to Wrigley, schedule a trip and make sure you get there early to chat with the ushers. You won’t be disappointed.Anyway, in the moments after the final out of the Cubs’ 5-0 win against the Dodgers in Game 6 of the NLCS, I couldn’t help butnotice the look of purejoy on Mary’s face as she sang along with Go, Cubs, Go, a look that told me the story of what the moment meant to an entire city, to a fan base that’s not constrained by geographical bounds. Acouple feet to her left, there was her friend Noah Syndergaard Jersey and fellow usherKathy West. Kathy couldn’t hold back the tears.I tweeted pictures of the two (Mary has the darker hair), and Twitter’s reaction to those images told me the looks on their faces spoke to baseball fans everywhere.Wrigley ushers. Yeah, this is something special. pic.twitter.com/HwxeZbooGj Ryan Fagan (@ryanfagan) October 23, 2016I played softball all my life, Mary told meas the celebration raged all around, and when I was a kid, I wanted to play in the major leagues. I was going to be a pitcher, the first woman pitcher. I played softball up until two years ago. I just love this game. I love it. I love it.SPECTOR: A lot has changed since Cubs’ last pennantThis is Mary’s 12th season as an usher at Wrigley. Both Mary and Kathy Zack Wheeler Jersey started as ushers in other spots in the stadium and worked their way to the prime location in the section directly behind the Cubs’ dugout. I asked Mary, who worked for the Chicago Transit Authority before retiring, why she wanted to be an usher at Wrigley.Because I love the Cubs and I love baseball, she said. It’s a dream retirement job.MORE: TV schedule for Cubs-Indians World SeriesAnd now it’s a dream trip to the World Series.It’s an amazing experience for the Cubs’ players and coaches and front office types, sure, but for the people like Mary and Kathy and all the other lifelong Cubs fans?MORE: Get Cubs championship gearIt’s unbelievable, Mary said.Yes, it is, Mary. Yes, it is.
