A's handle Orioles

Guillermo Moscoso had a quality start and the 4, in the second game series.

Moscoso (6-6) was charged with three runs -- two earned -- on five hits over six full frames.

Cliff Pennington went 3-for-4 with an RBI and run scored to help halt Oakland's four-game skid. Josh Willingham had a solo homer and Jemile Weeks drove in a run and scored once.

Brian Matusz (1-5), in his first big-league start since June 30, was touched for six runs on eight hits in 6 2/3 innings for Baltimore, which was coming off a 6-2 win in the opener of the set.
