The Seattle Mariners are edging closer to the top spot in the AL West after winning five of eight since the All Star break and each of their last three. They'll be looking to complete the sweep of this three-game set at Rogers Centre Sunday afternoon, and I would not be surprised to see Seattle win this one outright as a dog.

Here are my keys to the game:

1. Pitching - The Blue Jays hand the ball to J.A. Happ (12-3, 3.43) who spent the better part of last season with Seattle, but he's 1-1 with a 6.35 ERA in his career against the Mariners. Current members have a .376 batting average over 85 at bats against the left-hander and they'll be very familiar with him after last season. The Mariners counter with another left-hander in Wade Miley (6-7, 5.36 ERA). He's 1-2 with a 6.98 ERA in four career starts against Toronto, but 1-0 with a 4.63 ERA in the last two.

2. Seattle's Bats - The Mariners exploded for 14 runs and a season-high 19 hits in yesterday's blowout win. They've sure enjoyed playing in Toronto lately where they've won five of the past six meetings.

3. X-Factor - Toronto has lost six of its last eight when facing a left-handed starter.

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