SAN DIEGO — North Side, South Side, Chicago has become the center of baseball at the winter meetings.
The Cubs struck the first big deal among top free-agent pitchers, agreeing Tuesday night to a $155 million, six-year contract with left-hander Jon Lester.
"It's not often you get to win the lottery, and we won the baseball lottery this year," new Cubs manager Joe Maddon said. "Now it's up to us to put it into effect."
After losing 188 games over two seasons, the White Sox acquired starting pitcher Jeff Samardzija — a former Cub — from the Oakland Athletics as part of a six-player trade Tuesday. That came hours after they reached a $46 million, four-year deal with closer David Robertson.
"In our mind we're not finished yet," White Sox general manager Rick Hahn said. "We still know we have some other areas we need to improve and we're hopeful that in the coming days, and if not the coming days, then the coming weeks, we'll be able to fill a couple more voids in our roster."
On the South Side, the White Sox won the title in 2005 for their first championship since 1917.
The long-suffering Cubs are seeking their first World Series title since 1908.
They gave Lester a deal with an option for 2021 that, if it becomes guaranteed, would make the contract worth $170 million over seven seasons. The average annual value of $25.8 million is the second-highest for a pitcher behind Clayton Kershaw's $30.7 million as part of a $215 million, seven-year deal with the Los Angeles Dodgers that began this year.
