Prediction

Mariners 5, Padres 4

Money line (ML)

Slight “LEAN” to the MARINERS (+170) FIRST 5 INNINGS for a quarter unit because Seattle is 6-1 in Flexen’s seven starts, and I’m low on Paddack because of his limited pitching arsenal.

I’m a sucker for Seattle’s First 5 Innings value since I like Flexen more than Paddack but am laying off the full-game upset because the Mariners’ bullpen is mediocre and the Padres’ relief unit is elite.

Also, Paddack predominantly uses two pitches (fastball and changeup), and  I’m thinking Seattle’s struggling lineup could bust its slump vs. the predictable Paddack.

It’s not like Paddack’s fastball is extraordinary either since he grades in the 25th percentile for fastball spin and 23rd percentile in chase rate.

Run line/Against the spread (ATS)

“LEAN” to the MARINERS +1.5 (-115) for a three-fourths unit because it’s a wiser play than Seattle outright.

Furthermore, it’s a tight window we are trying to fit this Seattle upset into considering San Diego is one of the hottest teams in the Majors.

Over/Under (O/U)

PASS with a “lean” to the Over 7.5 (-115) because of the reduced juice, it’s a fade of the market, and these teams have a combined 9-5 O/U record when these starters are on the bump.

However, I’m somewhat banking on the Mariners getting to Paddack, and the Padres’ lineup is fully healthy and one of the best in the Majors. So I’m just going to stay away from the total.
