Mariners 3, Arizona 2

D-Backs' 1B Tony Clark inexplicably dropped a routine throw to first with two outs in the ninth, giving the M's a walk-off win. Felix Hernandez kept the Mariners in this one, and held a 1-0 lead in the eighth inning before surrendering a two-run homer. The M's won with a lineup of mostly backups and AAA starters, as six regulars were unavailable due to injury or family illness. M's 35-34, 2.5 GB. Box score. Next game Tues. vs. SD, 7:10 p.m.; Olson vs. Gaudin.
