Masterson allowed six runs and failed to make it out of the third inning in another rough outing in Oakland as the Boston Red Sox fell 9-2 to the Athletics on Tuesday night.
"Other than not pitching good, I'm fine," Masterson said. "Part of me wants to put it on the voodoo of the Coliseum. I never got close to getting comfortable."
The Coliseum has been a personal house of horrors for Masterson (2-2). He allowed six runs and six hits in 2 1-3 innings and fell to 0-6 with a 7.26 ERA in eight appearances at the Coliseum.
