OAKLAND -- Though Sean Nolin's A's debut ended in a 3-2 loss to the Mariners on Sunday, his employers got a six-inning glimpse of an arm that could prove effective in their rotation next year.
The left-handed Nolin, one of four players the A's reeled in from the Blue Jays for Josh Donaldson, was done in by a pair of costly walks in a three-run fifth -- he issued three overall and fanned one -- but impressed in his other five frames.
