Ken Griffey Jr. started what might be his final homestand with career homer No. 628, and Felix Hernandez added another strong effort to his AL Cy Young Award resume in the Seattle Mariners' 6-4 win over the Oakland Athletics on Tuesday night.

Griffey is staying mostly evasive about his future plans following the end of the season, but the Mariners icon jolted the meager crowd that showed up on a chilly night with a three-run homer off Oakland starter Trevor Cahill in the fifth inning.

Cahill became the 406th different pitcher to give up a long ball to Griffey in his storied career. Cahill (10-13) was just 13 months old when Griffey smacked his first career homer off Eric King on April 10, 1989.
