MESA, Ariz. (AP) _ Sammy Sosa hit his eighth home run of the spring, and the Chicago Cubs rallied for two runs in the bottom of the ninth inning Saturday to beat the Seattle Mariners 7-6.

Gary Matthews Jr. singled with one out in the ninth and scored on Damon Buford's double. Robert Machado singled home the winning run with one out off Brian Fuentes.

The Mariners lost their fifth straight game.

Sosa hit a long, two-run drive over the left-field wall in the first off Brett Tomko.

Chicago made it 4-0 in the second on Eric Young's two-run double. Ricky Gutierrez hit his first homer of the spring in the fourth.

The Mariners scored twice against Cubs starter Kevin Tapani in the fifth. Ichiro Suzuki had an RBI groundout, and John Olerud drove in the other run with a single.

Seattle scored four times in the sixth against minor league pitcher Jon Cannon. Bret Boone led off with a homer, Dan Wilson had an RBI triple and pinch-hitter Anthony Sanders had a two-run homer.

Notes: Cubs closer Tom Gordon had his right arm examined by team physician Dr. Michael Schafer on Friday. On Saturday, the team said Gordon is suffering from a ``triceps overload'' injury. Gordon, who had reconstructive elbow surgery in December 1999, injured himself early last week while lifting weights. The elbow is fine, but Gordon experienced pain in the triceps muscle. If all goes well, he could be back on the mound by the middle of the week. Gordon has appeared in three games this spring, going 0-0 with a 6.00 ERA.
