MESA, Ariz. (AP) — Dustin Ackley hit a three-run homer to extend his torrid start to spring training, and the Seattle Mariners beat the Chicago Cubs 10-3 on Thursday.

Ackley is 5 for 11 with four hits for extra bases: two doubles, a triple and a home run.

Cubs left fielder Alfonso Soriano is also off to a strong start, hitting his third homer — a solo drive off Kevin Millwood — and is hitting .625 (5 for 8).

Millwood allowed only one run on four hits in three innings, while Cubs starter Chris Volstad allowed one hit in three scoreless innings in his debut.
