TORONTO - R.A. Dickey couldn't keep the baseball in the yard again, but ultimately the Toronto Blue Jays were done in by a faltering bullpen.
After a respectable outing from Dickey, an eighth-inning implosion by veteran reliever Darren Oliver was enough to cost the Blue Jays in a 6-4 loss to the Oakland Athletics on Sunday afternoon at Rogers Centre.
Oliver, who hadn't allowed a run in his past five appearances, entered with the score tied and managed to retire Home Run Derby champion Yoenis Cespedes without difficulty. The rest of his outing didn't go as smoothly.
A single by A's right-fielder Josh Reddick and a walk to third baseman Josh Donaldson paved the way for second baseman Alberto Callaspo's two-run double, which Emilio Bonifacio almost came up with at wall in left field.
It was the 42-year-old Oliver's second-worst appearance of the season. He allowed four runs in a memorable bullpen collapse July 23 against the Los Angeles Dodgers.
