KANSAS CITY, Mo. (AP) – Alex Smith threw for 171 yards and two touchdowns in less than a half, and the Kansas City Chiefs’ offense looked the sharpest it has all preseason in a weather-shortened 34-10 victory over the Tennessee Titans on Friday night.

The game was called with 3 minutes, 50 seconds remaining after thunder rumbled and lightning streaked across the sky. Heavy rains had turned one end zone into a lake.

Smith was 16 of 18 before giving way to third-string quarterback Aaron Murray just before halftime. Murray played the rest of the game for the Chiefs (3-0), throwing for 146 yards with two touchdown passes and an interception as backup Chase Daniel got the night off.

Marcus Mariota got off to a slow start for Tennessee (1-2), misfiring on his first three throws. But the first-round pick out of Oregon was 7 of 8 for 99 yards the rest of the half.

SAN FRANCISCO (AP) – Rookie Kelby Tomlinson lined a bases-loaded single up the middle with one out in the ninth against previously unbeaten Kevin Siegrist, and the San Francisco Giants topped the Cardinals 5-4 on Friday night to snap St. Louis’ five-game winning streak.

Left fielder Brandon Moss grabbed another glove from the dugout and moved in to make a five-man infield, then Tomlinson found a hole against Siegrist (5-1).

Marlon Byrd hit a grand slam off 15-game winner Michael Wacha in the third inning for the Giants, who kept pace 2 1-2 games behind NL West-leading Los Angeles.

Javier Lopez (1-0) got Moss to line out to second in the ninth and Tomlinson quickly fired to first to double up Stephen Piscotty, who was off the bag.

Byrd’s eighth career grand slam gave the Giants eight for the season, a franchise record. Byrd last hit one on July 9, 2013, while with the Mets facing the Giants at AT&T Park.
