SEATTLE (AP) — Bartolo Colon outpitched Felix Hernandez to reach 18 wins for the fifth time in his career, Brandon Moss hit a three-run homer in the first inning and the Oakland Athletics beat Seattle 6-2 Friday night in the start of Eric Wedge’s final weekend as Mariners manager.Wedge told his bosses he will not return for next season, saying it became obvious he did not have a future with the club.“It’s got to the point where it’s painfully obvious to me that I just wasn’t going to be able to move forward with this organization,” he said before the game. “We see things differently and we talked about it, but it just got to the point where I couldn’t continue to move forward. Ultimately, I didn’t feel like I could continue to manage here with the circumstances the way they are.”Seattle, which has never reached the World Series is assured of its fourth straight losing season and dropped to 70-90.Oakland (95-65) remained two games back of Boston (97-63) with two games left in the race for best record in the AL and home-field advantage throughout the postseason.
