After much careful consideration, Jon Lester has decided to join the Cubs. According to sources, the deal is for 6 years and $155 million. Lester spent the first eight years of his career with the Red Sox before being traded to Oakland this past July. Lester has a career 3.58 ERA and averages 8.2 K/9 innings. (Source: ESPN)

Fantasy Impact: Theo Epstein has gone all in with this signing. The Cubs have the hitters, all they needed is a true number one pitcher. With all of the Cubs best prospects being hitters, free agency or trade was the only way to get a legitimate ace of the staff to come to Chicago. With his signing, Lester job now becomes the face of the franchise and will be the leader of the Cubs pitching staff. Lester has pitched in the AL all of his career, so a move to the Senior circuit should do nothing but help his numbers. Consider Lester a low SP1/high SP2 on your fantasy staff. A top 20 SP and top 75 player overall.

This will certainly get things rolling in San Diego, where MLB is holding the Winter Meetings. Lester joins a club that is intent on winning now and will be reunited with Theo Epstein and Jed Hoyer, the two who originally drafted him. (Source: Ken Rosenthal)

Fantasy Impact: Pencil Lester in on your fantasy cheat sheets as the clear ace of the Chicago staff and someone who can add tremendous value on your roster. Lester gave this decision a lot of thought and will be very comfortable with his role on the staff, which includes Jake Arrieta and Jason Hammel.

Fantasy Impact: That (apparently) leaves Boston, the Cubs and the Dodgers. No matter where he goes, he'll be a great fantasy option coming off a 2.46 ERA, a 1.10 WHIP and 9.0 K/9 in 2014. He's one of the most coveted free agents of 2014.
