While the out-of-town scoreboard monitored baseball's intriguing division races and wild-card chases the Angels resumed their late-season push toward a far more modest goal: Mediocrity.

"It's definitely not what you shoot for out of the gate" first baseman Mark Trumbo said of the team's quest to finish with a .500 record. "But the way things have gone this year it would actually be something positive."

The Angels opened 2013 with a $148-million payroll and World Series aspirations but when they fell to 55-71 on Aug. 21 their roster riddled with underachieving and injured players a .500 finish seemed impossible.

But that goal remained in reach Friday night after Chris Iannetta drove a run-scoring single off the left-center field wall to score Kole Calhoun in the 11th inning to lift the Angels to a 3-2 walk-off victory over the Seattle Mariners.

The Angels who are 20-7 since Aug. 23 improved to 75-78 the closest they have come to .500 since July 20 when they were 46-49. They have to go 6-3 over their last nine games to finish .500.

They could have won in regulation Friday if not for a mental mistake by reliever Michael Kohn who broke late to first on Dustin Ackley's potential inning-ending grounder to the right of Trumbo at first base in the seventh.

Ackley's infield single loaded the bases and Michael Saunders followed with a two-run single to center for a 2-0 Mariners lead.

But the Angels took advantage of an error a walk Erick Aybar's sacrifice bunt and Andrew Romine's clutch two-out two-run single to right his third hit of the game in the bottom of the seventh to tie the score 2-2.
