HOUSTON (AP) Shin-Soo Choo homered and drove in three runs as the Texas Rangers beat Houston for the eighth straight time, winning 6-2 Friday night and extending their AL West lead over the Astros to 4 1/2 games.

Houston star second baseman Jose Altuve exited early after being hurt in a collision with shortstop Carlos Correa while chasing a popup. Manager A.J. Hinch said Altuve didn't have a concussion and hoped to play on Saturday.

The Rangers improved to 16-7 this month while Houston lost its third in a row and fell to 7-15 in September. The Astros' lead for the second AL wild-card spot was whittled to one game over the Los Angeles Angels, who played later.
