Report: Cubs ink Lester

San Diego, CA (SportsNetwork.com) - Jon Lester has reunited with Theo Epstein.

Lester agreed to a six-year deal with the Chicago Cubs early Wednesday morning, according to a report.

The Cubs and Boston Red Sox were the only teams remaining in the Lester sweepstakes on Tuesday night after the San Francisco Giants and the Los Angeles Dodgers backed out, per reports.

Yahoo Sports! is reporting the pact to be for $155 million.

The 30-year-old Lester went 6-4 with a 2.35 ERA for the Oakland Athletics after he and outfielder Jonny Gomes were acquired in a blockbuster trade- deadline swap from the Red Sox for outfielder Yoenis Cespedes.

The southpaw went 16-11 with a career-best 2.46 ERA in 2014.

Lester is most known for his prowess in the postseason, where he is 6-4 with 2.57 ERA in 14 career appearances, including a perfect 3-0 mark with a sparkling 0.43 ERA in the World Series.

Lester has a 116-67 record with a 3.58 ERA over his nine-year career.

He turned down a $70 million contract extension from Boston during the spring, the team which he helped win two World Series titles.

Epstein became the youngest general manager in MLB history when the Red Sox hired him following the 2002 season and helped them win a pair of World Series prior to becoming the president of baseball operations for the Cubs in 2011.
