It isn't known what Oakland's chances are at this point to make a deal with the Red Sox, but they already pulled off one surprise by landing Samardzija and Hammel together in a deal with the Cubs.
Oakland would appear to have about the best depth of starters in baseball as is, but nothing should be put past GM Billy Beane.
An A's-connected source said they have "nothing close" at the moment. The deadline is 4 p.m. ET Thursday.
Heading into the past couple days, the Cardinals, Dodgers, Pirates, Orioles and Brewers have been considered the favorites for Lester, and perhaps one of them still lands the lefty. There were reports earlier suggesting the Orioles were getting close, but sources suggest they are just one of the teams in the mix.
The Cardinals don't look like they need a starter after landing Justin Masterson, and reports from Peter Gammons and Tim Brown suggest the Dodgers may be backing off. It is known LA has been hesitant to give up any of its top three prospects -- Corey Seager, Joc Pederson or Julio Urias.
