Phillies vs. Mariners Prediction and Odds for Monday, May 9 (Mariners Win Tight Contest)

We've got a matchup of two struggling teams today as the 13-16 Seattle Mariners host the 12-16 Philadelphia Phillies at 8:40 PM EST.

Seattle snapped a six-game losing streak yesterday in a 2-1 win over Tampa Bay while the Phillies are 1-5 in their last six.

Ranger Suarez gets the call for Philadelphia and he's been solid to open the year, amassing a 4.63 ERA over five starts. He's struggled to go deep in games but has yet to allow more than three earned runs in an outing.

The Mariners will counter with Chris Flexen and his 3.10 ERA. The 27-year-old lefty is coming off a two-hit, one-run performance against the Astros and has only given up four runs in his last three starts.

Can Flexen continue his strong play to get Seattle a second-straight win or will the Phillies snap out of their cold streak?

Phillies vs Mariners Prediction and Pick

Chris Flexen has long been one of my favorite pitchers to back. He's stayed under the radar but his results have remained consistent. In his last three starts, he's given up only four runs across 18.2 innings. Flexen doesn't rack up many strikeouts, but the weak contact he generates allows the Mariners' top-10 defense to keep bats at bay.

On the other end, Ranger Suarez is in the 86th percentile among pitchers in average exit velocity, but his underlying metrics are unkind otherwise. He has a 5.30 FIP (Fielding Independent Pitching) while ranking in the 13th percentile in expected ERA and 1st percentile in fastball spin rate.

Seattle's offense presents an easy matchup for Suarez, though. They've scored three or fewer runs in five of their last six contests and have been shut out three times in that span. I expect a tight game as a result, but one the Mariners should win.

Flexen gives the Mariners a starting pitching advantage and they have the superior bullpen to Philly's 26th-ranked unit. Their defense is ninth in MLB in defensive runs saved compared to 25th for Philadelphia, so offense is the only area that the Phillies have the edge.

Offense is obviously a crucial edge to have, but Flexen should provide enough on the mound to mitigate that advantage. I'm backing Seattle and the under in a close-contest.

Pick: Mariners (-122) and Under 7.5 (-110)
