Williams fired a scoreless eighth inning and picked up his eighth win of the season Saturday against the Cubs.
Williams issued his fifth walk in five appearances Saturday, but he also struck out the side for the ninth time this season and wound up with the win when Manny Pina hit a go-ahead homer in the home half of the eighth. Williams was tagged for four earned runs by the Giants in his first September outing, but those are the only runs he has allowed in 26 appearances since June 23.
