Sporting a 1-4 record in their last five games, the Seattle Mariners opened as surprising -115 favorites in Game 1 of their three-game series with the Philadelphia Phillies on Monday at Citizens Bank Park.
The Mariners have lost the last two of their three-game series with the New York Mets, dropping to 1-4 in their last five games and 68-57 in the season. Seattle would have overtaken the Houston Astros for the No.1 spot in the AL West had they swept the Mets. Instead, the Mariners found themselves 1.5 games behind the 69-55 Astros in the division standings.
The Phillies outgunned the Washington Nationals 11-9 in Game 4 to salvage a 2-2 tie in their four-game series over the weekend. It might not be a convincing win over the worst team in the NL East, but scoring 11 runs in a single game is a good sign for the Phillies, who barely averaged three runs a game in the last five games before Sunday’s ballgame.

Our Seattle Mariners vs Philadelphia Phillies Prediction
Bet on the Phillies to win (-105).
The Phillies are a solid 6-3 in their last 9 home games. Starting pitcher Ranger Sanchez may look like a hot mess right now, but expect him to put up better numbers against a team he held scoreless through six innings three years ago.
The Mariners are 1-4 in their last five games, averaging 4.2 runs per game and pitching a 5.83 ERA in this stretch. The numbers might not appear that bad at first glance, but getting outplayed by the struggling Mets in two consecutive games isn’t a good look for a team with championship aspirations. Starter Logan Gilbert carries a 3.14 ERA in his last five starts, but he’s 0-3 in his last three starts against the Phillies, surrendering an average of 3.0 earned runs per game.
Our betting prediction for the Philadelphia Phillies vs. the Seattle Mariners: the Phillies will win.
