Game outlook

The Mariners and Rays open a weekend series in Florida with both teams firmly in the playoff picture. Seattle looks to jump back into the win column after losing the final game of a three-game series against the Reds, while Tampa Bay came away with an 8-6 win in 11 innings during the middle of a three-game set with the Red Sox. This will be the second series between these two teams this season, with the Mariners taking two of three at home in June. Luis Castillo (ERA: 3.24) will be the starter for Seattle and Zack Littell (ERA: 4.69) will face off against him for the Rays, with Seattle favored at -115 with the current line at -133.

Tampa Bay Rays Analysis

The Tampa Bay Rays had won their most recent game against the Red Sox in walk-off fashion on Tue. They currently stand 84-55 overall and second in the AL East, 3.5 games behind the Orioles. The Rays have the top wild card spot in the American League playoff picture. Offensively, they are #4 in power ranking (scoring an average of 5.35 per game) and #1 for defense (giving up an average of 4.01 points per game). Starting pitcher Zack Littell is 3-4 with a 4.69 ERA, a 1.263 WHIP, 8 walks and 52 strikeouts over 63.1 innings. He has a 1-2 record with 28 strikeouts in 32.2 innings at Tropicana Field. The Mariners have only won 1 out of the last 3 matchups against Tampa Bay.

Mariners' Castillo Ready to Take Center Stage in Wednesday's Playoff Match-Up

Entering Wednesday's playoff matchup, the Rays have a cushion to work with; whereas the Mariners are trying to secure two spots amongst three teams. Castillo has been an anchor to the Seattle rotation and, although Littell has had an up-and-down season, he has been thrust into a starting role due to several players being injured. While both teams have strong batting lineups, Castillo's performance should provide an edge to the Mariners in the opener.

My Prediction: Rays +1.5 (-143) to cover
