The Mariners slipped to four games back of first place Texas in the Al West with an extra-innings loss last night. We've seen a couple of low scoring games in the first two games of this series at Safeco, and another pitcher's duel is expected here on Sunday.

Here are my keys to the game:

1. Pitching - Wade Miley will get the start for Seattle, and he comes in riding a nine game unbeaten streak. Miley (6-2, 5.27 ERA) tossed seven scoreless innings, giving up just four hits in a home win over Cleveland in his last start. The southpaw is 3-1 with a 4.22 ERA in five starts at Safeco this season. The Rangers send Cole Hamels to the mound, and he hasn't been sharp in recent starts at Safeco, going 1-1 with a 5.54 ERA.

2. Previous History - The Mariners have prevailed in eight of Miley's last nine starts, and seven straight when he's had four days of rest.

3. X-Factor - The Rangers have been playing with a depleted lineup, missing starters Adrian Beltre and Shin Soo Choo due to injury.

Selection: This is a play on the Seattle Mariners +1.5 (8*)
