The Braves are 3-12 in their last 15 games and now look to be without their best offensive player, Justin Upton. He suffered a left hamstring injury in Thursday's loss to the Dodgers.

While the Braves are a mere one game above .500, the A's have the best record in baseball at 73-48. Oakland has won 10 of its last 12 interleague games and 19 of their last 26, while the Braves are 4-10 in their past 14 interleague matchups.

Oakland leads the majors in runs averaging 4.8. Atlanta ranks 29th averaging 3.7 runs per game.

The A's are 20-13 versus southpaws and facing lefty Alex Wood, who is pitching well but coming off a career-high 124-pitch count game this past Sunday.

Oakland starter Jason Hammel had a rocky start with the A's, but has settled down during his last two starts and has a good recent history versus NL opponents. The right-handed Hammel has given up just one run in his last two starts spanning 12 innings. He has a 3.03 ERA in 16 starts this season against NL foes. Atlanta has lost 14 of its last 17 when facing a righty.
