Yoenis Cespedes hit a two-run home run and Josh Reddick and Jonny Gomes added solo shots Thursday in Oakland\'s 4-1 win over the Seattle Mariners in Tokyo. The win gave the Athletics a split of the season-opening series in Japan. Seattle was a 3-1 winner in 11 innings Wednesday. Oakland starter Bartolo Colon (1-0) allowed three hits and struck out six in eight innings and Grant Balfour pitched the ninth in getting the save. Oakland had just two hits and a walk off Seattle starter Jason Vargas but touched the Mariners\' bullpen for five hits, including the three home runs, in 1 2/3 innings. Seattle led 1-0 on a Justin Smoak home run that opened the seventh. Vargas walked Coco Crisp and then got an out but was replaced by Shawn Kelley (0-1). Kelley got a fielder\'s choice but Cespedes followed with a smash into the seats beyond left-center field. Seattle changed pitchers but Reddick greeted George Sherrill with a towering drive into the right-field seats. Gomes made the score 4-1 with a two-out home run to left-center in the eighth off Steve Delabar.
