Cal Raleigh’s Late Blast Lifts Mariners Over Rays in Series Opener

The Seattle Mariners opened their three-game series against the Tampa Bay Rays with a dramatic 3-2 victory on Friday night, thanks to a clutch three-run homer from Cal Raleigh in the bottom of the eighth inning. The blast, his MLB-leading 43rd of the season, came with two outs and flipped the game in Seattle’s favor after trailing 2-0.

For bettors and fans tracking MLB trends, Raleigh’s power surge has been a significant storyline this season. You can follow updated MLB picks and projections at Scores and Stats MLB Picks.

Brash Steps Up in High-Leverage Save Opportunity

After Raleigh’s homer gave Seattle the lead, the Mariners turned to reliever Matt Brash with closer Andrés Muñoz unavailable after pitching the previous two games. Brash delivered under pressure, striking out the side in order for his second save of the season.

The right-hander, who missed all of last year following Tommy John surgery, is now 1-0 with a 1.20 ERA. The moment was among the most intense of his comeback.

“When you’ve got the adrenaline pumping, it’s just different,” Brash said. “Closing games is always special, and with a playoff push in front of a loud crowd, it felt incredible.”

Rays See Streak Snapped Despite Strong Start

The Rays had been riding a two-game winning streak, powered early by homers from Brandon Lowe and Junior Caminero. Starter Drew Rasmussen was sharp, tossing six scoreless innings before the bullpen faltered.

Reliever Griffin Jax allowed singles to J.P. Crawford and Cole Young before Raleigh’s decisive swing. Tampa Bay manager Kevin Cash acknowledged the challenge Raleigh posed, calling him “the wrong guy to face” in that spot.

Saturday’s Pitching Matchup: Boyle vs. Evans

Saturday’s contest will feature right-hander Joe Boyle (1-1, 2.30 ERA) for Tampa Bay against rookie Logan Evans (5-4, 4.30 ERA) for Seattle.

Boyle enters after a no-decision against the Los Angeles Dodgers, where he allowed just three hits over five scoreless innings. He previously faced the Mariners in relief last season, throwing 1 2/3 scoreless frames.

Evans, unbeaten at home this year with a 3-0 record and a 3.03 ERA, will be making his first career start against the Rays. His last outing was a five-inning, three-run effort in a 5-4 win over Texas.

Betting Perspective

With the Mariners riding the momentum of Raleigh’s late-game heroics and Evans’ strong home record, Saturday’s matchup could offer intriguing value for bettors. The Rays’ offense will look to bounce back, while Boyle’s recent dominance on the mound could keep this a low-scoring battle.
