Mariners vs Phillies Predictions and Picks
"Both Castillo and Luzardo have put together solid 2025 seasons, but I have a hard time backing the Mariners – who have lost four in a row – on the road in this one .... Meanwhile, the Phillies have improved to 18 games over .500 at Citizens Bank Park in this series, and they're 14-11 when Luzardo is on the mound in 2025 .... The Phillies are ninth in MLB in batting average and 10th in OPS over the last 15 days, and I think they give Luzardo enough run support to pick up a win this afternoon." — Peter Dewey, Sports Illustrated
"I'm backing the Phillies here. I get the case that you could make for Seattle as Luzardo has had his issues at times this season. However, Philadelphia continues to be the better team while the Mariners are just falling apart right now, losing four straight and six of seven. The Mariners need to just get back home, but they don't have that luxury right now and I just think that the Phillies find a way to get the job done here as well. Give me Philadelphia." — Chris Ruffolo, PickDawgz
"The Phillies are poised to sweep this series against the Mariners by once again relying on their offense to do the heavy lifting .... 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 prediction: Phillies." — Lou Aguila, SportyTrader
