OAKLAND -- In a season that has featured one low point after another, the Red Sox may have finally bottomed out Friday night.
The Red Sox were humiliated by the Oakland A's, 20-2, handed their fourth straight loss on the current West Coast road trip.
The 20 runs allowed were a season high for the Red Sox, eclipsing the 18 they gave up to the Texas Rangers April 17 and the 18-run differential represented the most one-sided beating the Sox have absorbed since 2000.
It also marked the first time the Sox had allowed 20 or more runs in the game since Aug. 21, 2009 when they allowed 20 to the New York Yankees.
The loss closed the books on a disastrous month of August, which saw them suffer 20 losses for the first time since the team's infamous September swoon at the end of the 2011 season.
Worse, 13 of the 20 runs were driven in by former Red Sox players. Josh Reddick and Brandon Moss each drove in four runs with Reddick belting his first career grand slam in a nine-run seventh inning, while George Kottaras added another five RBI. Kottaras, who had just one homer before Friday, hit two in the same game for the first time in his career.
Aaron Cook was blasted for six runs in just 2 23 innings. Of the six Red Sox relievers that followed him to the mound, only Junichi Tazawa was unscored upon.
Jarrod Saltalamacchia had a solo homer for the first Red Sox run. The second scored in the seventh on a groundout by Scott Podsednik.
