Gilbert (9-12) allowed one hit and struck out seven without walking a batter over 5.2 scoreless innings to earn the win Sunday over the Athletics.
Gilbert was perfect into the sixth inning before Nick Allen hit a two-out single to end his day. Gilbert ends the regular season as the major-league leader in innings pitched with 208.2, two ahead of Kansas City's Seth Lugo. While he alternated between good and poor starts in September, Gilbert was generally one of the steadiest members of a strong Seattle rotation. He finished the campaign with a 3.23 ERA, led all major-league starters with a 0.89 WHIP and added a 220:37 K:BB over 33 starts, though he missed the 10-win mark for the first time in three years.
