The Philadelphia Phillies opened at -144 ahead of Wednesday’s Game 3 against the Seattle Mariners. The Phillies are attempting to complete a sweep after beating the Mariners in the first two games convincingly at Citizens Bank Park.

The Phillies are rolling, having won four of their last five games to stay atop the NL East with a 73-53 record. Pitching numbers might not look good right now with a 4.91 ERA in the last five games, but the Phillies' offense is torching their opponents by averaging 7.3 runs per game on a .305 batting average in the said five-game stretch.

The Mariners (68-59) have dropped their last four games, though they are miraculously still 1.5 games within the AL West leaders, the Houston Astros (69-57). Seattle’s pitching isn’t in good shape right now. Over the last five games, they have given up an 8.12 ERA and 2.4 home runs per ball game, resulting in these heavy losses against the Mets and the Phillies.

Our Philadelphia Phillies vs Seattle Mariners Prediction

Fearless Forecast: The Phillies ride on their hot offense to win the series, covering -1.5 runs.

The Phillies are poised to sweep this series against the Mariners by once again relying on their offense to do the heavy lifting. Philadelphia, 4-1 in their last five games at Citizens Bank Park, will start left-handed pitcher Jesus Luzardo, who is 3-2 with a 3.90 ERA in his last five starts. Meanwhile, the Mariners will dispatch right-handed pitcher Luis Castillo, who gave up six earned runs over four innings in a 9-11 loss to the Mets. There’s no question that Castillo can put together a strong start despite coming off an ugly stint. However, with the Mariners also struggling recently with a 6.05 ERA in their last five games, it’s safe to say that Seattle will need to step up their play to avoid a sweep at the hands of the Phillies.

Our betting prediction for the Philadelphia Phillies vs. the Seattle Mariners: the Phillies -1.5 Runs.
