A's pitchers have compiled an impressive 2.83 ERA over their last 21 games. Their starters, meanwhile, have walked three batters or fewer in 37 consecutive games, which is the second-longest streak in Oakland history. The longest is a 41-game stretch in 2000. For the season, the 211 walks A's starters have issued are the fewest in the AL. The A's have hit the second-most homers in the Majors since the All-Star break with 77, trailing only the White Sox 78. George Kottaras has homered in back-to-back games for the first time this season after hitting a two-run homer in the fourth inning on Saturday. Mariners: Montero stepping up
Jesus Montero extended his hitting streak to seven games by going 2-for-4 on Saturday. Over the seven-game stretch, Montero is batting .423 with three multihit games and one homer. Since the All-Star break, he's hitting an even .300 after batting just .245 over 274 at-bats before the Midsummer Classic, giving him a .266 mark over 117 games this season with 15 homers and 54 RBIs. Despite Saturday's loss, the Mariners have won 18 of their past 24 games at Safeco Field. Worth noting
The A's are 8-7 in the season series with the Mariners, with four remaining games. Coco Crisp has faced Vargas more than any other A's player, batting .333 against him with one homer in 27 career at-bats.
