The Philadelphia Phillies (65-43) take on the Seattle Mariners (57-53) Friday in the opener of a 3-game set at T-Mobile Park at 9:40 p.m. ET (MLB Network). Let’s analyze BetMGM Sportsbook’s lines around the Phillies vs. Mariners odds and make our expert MLB picks and predictions for the best bets.

Season series: First meeting; Phillies won 2-1 last year

The Phillies have hit a rough patch, losing 4 in a row and 6 of 7 before Thursday’s off-day. They lost 2 of 3 to Cleveland and were swept by the New York Yankees, both series at home, and they’re 7-13 over the last 20 Games. DH Kyle Schwarber is back on a binge, hitting .375 with 3 homers and 6 RBIs in his last 5 Games.

The M’s lost 2 of 3 to the Boston Red Sox, but they had a 4-2 road trip. Newly acquired OF Randy Arozarena is producing, hitting .316 with 1 homer and 2 RBIs in his last 5 Games. Their trade deadline additions have helped steer the ship in the right direction.

Phillies at Mariners picks and predictions

Prediction

Phillies 3, Mariners 2

Moneyline

Woo has been really good at avoiding hard contact. He has only given up 3 extra-base hits (no homers) to right-handed batters this season. Conversely, the damage has come from lefties, who have touched him up for 4 doubles and 4 homers in 105 at-bats. For Philly, Phillips has been awesome in his last 2 starts. He hasn’t allowed a run in 15 innings.

I’ll take the PHILLIES -110.

Run line/Against the spread

One prop that sticks out to me is TYLER PHILLIPS UNDER 1.5 WALKS (+110). He has allowed a total of 2 walks in 3 starts, and they came in separate starts.

Over/Under

It’s slated to be 86 degrees with a 3-mph gust blowing out to left-center. The M’s are 6-4 O/U in their last 10, and the Phils are 5-5. In a spacious ballpark without much wind and 2 pitchers that avoid hard contact, I like the UNDER 8 (-110).
