Chris Sale pitched a complete game four-hitter on Thursday night to become the first Major League pitcher since 2008 to win his first nine starts.

The Chicago White Sox edged the Houston Astros to snap their season-high four game losing streak.

"I just see him continuing to get better as the season goes along, as he goes through his career," Robin Ventura said. "He's confident. He's doing a lot of different things that he hasn't done in the past as far as just adding a little bit [to his pitches], taking a little off in the heat of the moment."

Sale walked none and struck out a season-high nine en route to his second straight complete game. No other pitcher has more than seven victories in the big leagues this season.

"Just keep doing more of the same," Sale said of the next step. "You got to stay on it, what you've done, where you've been, just try to better yourself. Any athlete that respects the game will tell you that."
