The A's aren't done tinkering with the 2016 roster, but a few parts are coming into clearer focus: In is Jed Lowrie, probably out are either Brett Lawrie or Danny Valencia, Sonny Gray is indeed off the market and Oakland still has quite a bit of payroll flexibility to keep tinkering for next season and beyond.
Where the A's have holes depends on where you see Mark Canha, Jed Lowrie, an untraded Lawrie or Valencia playing. The good news is that if opportunity allows the A's to land a good 1Bman, they can move Canha to LF and if the chance to land a LFer falls in Oakland's lap they can put Canha at 1B.
