Theo Epstein has officially been introduced as the new president of baseball operations for the Chicago Cubs. Epstein joins the Cubs after a mostly successful 10 year stint with the Boston Red Sox.

“I wouldn’t trade my time with the Red Sox, but I do think it was time to move on. They’re in great hands and they have a terrific future laid out in front of them, and I was ready for the next big challenge. And this is certainly the ultimate challenge. I’m ready to embrace it and move forward,” Epstein told reporters Tuesday in his first press appearance at Wrigley Field.

Epstein left Boston with one year still left on his contract as general manager. The Red Sox and the Cubs have yet to determine compensation for the deal.

Esptein helped the Red Sox win two World Series championships after 86 years without one. He says he thinks he could help the Cubs break their 103-year-old drought.

“We’re going to make a foundation for sustained success a priority. That will lead to playing October baseball more often than not down the road. And once you get in October, there’s a legitimate chance to win the World Series. I believe we can do it, and I look forward to helping,” Epstein said.

The Cubs finally made the announcement that Epstein would be moving to the Cubs on Friday night, but held off on the news conference until Tuesday, an off-day for the World Series.
