The AL West-worst Oakland Athletics recorded their fourth win in six games when they defeated division-rivals the Seattle Mariners 11-5 last night. Another high-scoring encounter is in the cards Tuesday night as two unreliable pitchers will take the hill.

Here are my keys to the game:

1. Pitching - The A's hand the ball to Jesse Chavez (7-12, 3.75 ERA) who had posted a 6.57 ERA over five starts before holding the Dodgers to two runs in eight innings of a 5-2 home-win Wednesday. His road-ERA of 4.73 is almost two runs higher than his mark home in Oakland though and he's lost each of his last four starts against the Mariners behind a 4.75 ERA. The M's will counter with Mike Montgomery (4-6, 4.16) who is 0-4 with a 7.45 ERA in his last eight starts. The 26 year old left-hander held Oakland to run on six hits in 5 2/3 innings of a 2-1 win on July 5, but he'll face a revived Oakland offense here.

2. Situational - Nine of Chavez's last 13 starts overall and three of his last four against Seattle have gone over the total. The same is true for 21 of the Mariners last 29 games at Safeco Field.

3. X-Factor - The current members of the Mariners are batting .303 over 119 at bats against Chavez with Nelson Cruz going 5-for-11 with a double and a pair of homers.

Selection: This is a play on OAK@SEA to go over the total (10*)
