Seattle Mariners vs Toronto Blue Jays Picks and Predictions May 9th 2025

Blue Jays Look to Build Momentum in Series Opener vs. Red-Hot Mariners

After snapping a four-game skid with a much-needed comeback win on Thursday, the Toronto Blue Jays head into Seattle hoping to carry that momentum into a tough three-game set against one of the hottest teams in baseball. But this time, the usual flood of fan support from across the Canadian border may not follow.

Border Politics Dim “Home Away From Home” Vibe

Traditionally, games in Seattle have felt like home contests for the Blue Jays, thanks to the surge of Canadian fans who travel down to watch. But this weekend, attendance from the north is expected to take a significant hit. Political tensions and comments from former U.S. President Donald Trump have reportedly led to many Canadians staying home, with travel bookings cut nearly in half.

While the crowd may be smaller, the stakes remain high as the Blue Jays attempt to climb back into the playoff picture against a scorching Seattle squad.

Toronto Offense Awakens in Anaheim

The Blue Jays showed signs of life in Thursday’s 8-5 win over the Angels, rallying from a four-run deficit. Daulton Varsho led the charge with a 3-for-4 performance that included a home run and three RBIs, while Vladimir Guerrero Jr. also notched three hits. Anthony Santander delivered a clutch, two-run go-ahead single during a four-run sixth inning.

Toronto’s eight-run outburst matched their season high and could serve as a turning point for an offense that has been inconsistent through the first month and a half of the season. If you’re tracking MLB game trends and picks, it’s worth watching whether Thursday’s outburst was a blip or a breakthrough.

Mariners Keep Winning With Grit and Guts

Seattle Mariners enters the weekend series riding the high of nine straight series wins, their longest streak since the historic 2001 campaign. Despite injuries to key starters Logan Gilbert and George Kirby, the Mariners have continued to grind out victories, with contributions coming from across the roster.

Wednesday’s come-from-behind win over Oakland was just the latest in a string of resilient performances. Newcomer Leody Taveras delivered in his debut, while Rowdy Tellez launched a game-tying three-run bomb.

Veteran Arms Face Off Friday

The series opener will feature a solid pitching matchup between Kevin Gausman (2-3, 3.83 ERA) for Toronto and Luis Castillo (3-2, 3.29 ERA) for Seattle. Gausman, despite a strong outing last week (six scoreless innings against Cleveland), hasn’t won a game since April 15. He owns a deceptive 1-4 record in 11 career outings vs. Seattle, along with a stellar 2.77 ERA.

Castillo, meanwhile, is coming off back-to-back quality starts. He’s 2-2 lifetime against Toronto and earned a win against them just three weeks ago.
