The 31-year-old Moss had a monster first half of the season and was selected to his first All-Star team in July. But he tailed off in the second half, batting just .173 with four homers after the All-Star break. Moss finished the season with a .234 average, 25 homers, 81 RBI and .772 OPS. The A's lost to the Kansas City Royals in the American League Wild Card game.
