Brian Matusz is a former first-round pick, a 24-year-old the Orioles hope will ascend to the top of their rotation one day.

Around the A's clubhouse, however, Matusz is a cure for ill bats. The A's continued their dominance of the left-hander Tuesday, tagging Matusz for six earned runs in an 8-4 victory at O.co Coliseum.

In five career games against Matusz, the A's have scored 20 runs in 29?2/3 innings. Coupled with a workmanlike effort from A's starter Guillermo Moscoso, the latest offensive outburst against Matusz was more than enough to snap Oakland's four-game losing streak in front of an announced crowd of 12,325.

"We had (Matusz) on the ropes early," A's manager Bob Melvin said. "Early on, you wouldn't have thought he would be out there in the seventh inning."

Looking back, Matusz probably shouldn't have lasted that long.
