MESA, Ariz. (AP) Miguel Tejada's two-run homer capped a seven-run Oakland rally in the eighth inning that carried the Athletics to a 13-11 victory over the Chicago Cubs on Tuesday.

Sammy Sosa and Chris Stynes each hit two-run homers and Joe Girardi, who had four of Chicago's 21 hits, had a solo shot for the Cubs.

The A's trailed 8-6 entering the eighth before roughing up Courtney Duncan and Carlos Zambrano.

Singles by pinch-hitter Scott Hatteberg, Carlos Pena and Mike Colangelo filled the bases and finished Duncan. A walk to Jeremy Giambi forced in one run, a single by Adam Piatt drove in two runs, a single by Olmedo Saenz and an error on the relay by second baseman Bobby Hill delivered two more runs before Tejada completed the outburst with his third spring homer.

Sosa's homer, his team-leading fifth of the exhibition season, sailed over the left-field scoreboard and triggered a five-run fifth-inning that gave Chicago a 7-6 lead.

The drive followed a leadoff bunt single by Corey Patterson and cut Oakland's lead to 6-4. Stynes' homer, his second, came two outs later and scored Roosevelt Brown.

The Cubs went ahead 7-6 on Girardi's third straight hit, a walk to pitcher Alan Benes and a double by Delino DeShields.

Moises Alou, playing for the first time since March 18 after being sidelined with a strained muscle in his left side, singled in the Cubs' first run in the third. Girardi hit his first spring homer in the fourth, Alex Gonzalez singled in a run in the sixth, and the Cubs got three runs in the eighth on Girardi's RBI single and Angel Echavarria's two-run triple to right which Piatt lost in the sun.

Chicago's first seven runs were off Erik Hiljus. He worked 4 2-3 innings and gave up 12 hits with two walks and three strikeouts.

Jason Bere started for the Cubs and lasted only 2 2-3 innings. After pitching two scoreless innings, he was battered for five runs before being knocked out in the third.

Eric Byrnes' leadoff homer, his third and team-leading 15th RBI, began the barrage against Bere. After two outs, seven consecutive batters reached base. Giambi singled and Frank Menechino walked, both runners scoring on Terrence Long's triple.

Eric Chavez walked and Tejada singled in Long. Greg Myers' ground-rule double drove in Chavez.

Cody McKay singled in the A's other run in the fifth.

Notes: The Cubs will play their final home exhibition game Wednesday at HoHoKam Park, and will send opening day starter Jon Lieber against Arizona's Randy Johnson. ... A's catcher Greg Myers left after three innings with a bruised left wrist.
