Philadelphia Phillies at Seattle Mariners odds, picks and predictions

Analyzing Monday’s Philadelphia Phillies at Seattle Mariners odds and lines, with MLB expert picks and predictions.

The Seattle Mariners (13-16) host the Philadelphia Phillies (12-16) Monday for the opener of their 3-game interleague series at T-Mobile Park. First pitch is scheduled for 9:40 p.m. ET. Let’s analyze Tipico Sportsbook‘s lines around the Phillies vs. Mariners odds with MLB picks and predictions.

Seattle snapped a 6-game losing skid and prevented a sweep in its 4-game series by beating the Tampa Bay Rays 2-1 in extra innings Sunday.

Philly is 2-5 overall in the last 7 games and has lost 3 straight series but split a doubleheader with the New York Mets Sunday.

Phillies at Mariners picks and predictions

Prediction

Mariners 5, Phillies 1

Money line

BET MARINERS (-120) because Flexen pitches better at home and Seattle’s lineup hits better at home. The Mariners are 1st in both wRC+ (147) and BB/K (0.62) at home, 3rd in wOBA (.354) and 9th in hard-hit rate (32.0%), per FanGraphs.

I can excuse Flexen’s 1-4 overall record because he has a 3.10 ERA even though 4 of his starts have been against elite ball clubs in the Houston Astros (twice), Tampa Bay Rays and Minnesota Twins.

On the other hand, the Phillies are just 3-7 overall on the road, 8-13 overall vs. right-handed starters and have worse advanced hitting numbers against righties.

The MARINERS (-120) money line is my favorite wager in this game.

Run line/Against the spread

SPRINKLE on the MARINERS -1.5 (+170), if at all, because they could put this game out of reach vs. Philly’s weak bullpen, which ranks just 18th in xFIP, 25th in WHIP and 20th in hard-hit rate.

Over/Under

BET UNDER 7.5 (-110) because Philly’s lineup ranks 20th in wRC+ (94) and 22nd in hard-hit rate (31.0%) vs. right-handed pitching. Whereas Seattle’s lineup ranks 22nd in wRC+ (96) and 23rd in hard-hit rate (30.1%) against lefties.
