That starts with table-setters like Thairo Estrada and continues with veteran bats like Michael Conforto and Mike Yastrzemski. With Adames slotted in as a central contributor and Verlander on the mound, the Giants are hoping their mix of old-school grit and new blood is enough to hang in a deep NL West. Seattle, meanwhile, is pushing forward with its youth movement. After a strong 85–77 campaign that ended in disappointment, the Mariners have returned with a lineup that’s fast, flexible, and eager to prove it’s ready for prime time. Bryce Miller, the 25-year-old right-hander starting Friday’s game, is a key piece in the Mariners’ pitching puzzle. He showed flashes of brilliance in his rookie year and will be expected to build upon that, especially with ace George Kirby starting the year on the IL. The Mariners’ offense is a mix of speed and pop, with Julio Rodríguez expected to lead the charge. They’re looking to improve on last year’s middling contact metrics (7.4 hits per game) by emphasizing situational hitting and working deeper into counts. If they can support Miller with some early run production and avoid giving away outs, Seattle has every chance to steal the opener on the road. Ultimately, this game represents two teams at very different points on their competitive timeline. The Giants are trying to make one last playoff push with veterans and high-floor contributors, while the Mariners are hoping their upside-driven roster can start cashing in on potential. Friday’s game may not decide much in the grand scheme of the 162-game grind—but it will give us a glimpse into how each of these teams plans to chase relevance in 2025.
omg Becky, look at that bobblehead

Seattle Mariners MLB Preview
The Seattle Mariners open a crucial early-season road trip by visiting Oracle Park on April 4, where they’ll face the San Francisco Giants in the Giants’ home opener. For Seattle, the mission is clear: build on last year’s 85–77 record and finally break through to a deep playoff run. The Mariners have been hovering on the edge of contention for the past two seasons, armed with an exciting young core but often undone by streaky offense and injuries at inopportune times. Now, with their roster largely intact and many of their prospects turning into productive big leaguers, the organization is hoping 2025 is the season when it all clicks. A win in front of a hyped-up Oracle Park crowd would be an early statement—one that says the Mariners aren’t just here for the vibes, they’re here to win. Starting Friday’s game is 25-year-old right-hander Bryce Miller, one of several young arms in the Mariners’ rotation tasked with carrying more of the load this season. With ace George Kirby currently sidelined due to shoulder inflammation, Miller gets an early-season opportunity to solidify his standing. He flashed plenty of promise in his rookie year, showing a live fastball and the ability to work deep into games when his command was on. His biggest challenge will be maintaining consistency and executing under pressure, especially in environments like San Francisco’s home opener. The Giants’ lineup doesn’t feature many intimidating names, but it’s filled with savvy veterans who feast on mistakes.
If Miller can stay ahead in counts and mix his secondary stuff effectively, he could turn in a strong outing and keep the game close enough for the offense to do its job. Speaking of offense, the Mariners know it’s time to stop relying on potential and start producing runs. Their lineup features breakout star Julio Rodríguez, whose mix of power, speed, and charisma has turned him into the face of the franchise. But the burden can’t fall on him alone. Players like Cal Raleigh, J.P. Crawford, and Ty France need to contribute more consistently if this team hopes to avoid the midseason scoring droughts that haunted them last year. Seattle averaged just 7.4 hits per game in 2024—a number that simply won’t cut it in a division featuring the Astros and Rangers. Manager Scott Servais has emphasized improved situational hitting and plate discipline this spring, and this road series will offer a good early test. Oracle Park is not an easy place to hit, but it rewards teams that can work counts, go gap-to-gap, and capitalize on mistakes. Seattle will need to play fundamentally sound, aggressive baseball to scratch out runs against a savvy veteran like Justin Verlander. Defensively, the Mariners remain one of the more athletic teams in baseball, especially in the outfield where Rodríguez and company cover serious ground. The infield is steady, with J.P. Crawford providing leadership and range at shortstop, and their catching tandem doing a solid job managing the staff. With a strong bullpen and the kind of pitching depth that allows them to stay in games even when the offense is cold, the Mariners aren’t flashy—but they’re dangerous. If they can leave San Francisco with a win, it’ll reinforce what they already believe: this is the year they stop knocking on the door and start kicking it in.

San Francisco Giants MLB Preview
The San Francisco Giants enter their 2025 home opener against the Seattle Mariners with cautious optimism and a renewed sense of direction. After finishing the 2024 season at 80–82 and missing the playoffs for a third straight year, the front office pulled the trigger on significant changes—none bigger than bringing franchise icon Buster Posey back into the fold as team president. Posey’s return signaled a clear cultural and competitive reset, and the team followed that with its biggest financial commitment in years, signing shortstop Willy Adames to a seven-year, $182 million contract. The Giants aren’t just patching holes—they’re trying to lay the foundation for a competitive window in the fiercely competitive National League West. Friday’s home opener at Oracle Park, against an up-and-coming Mariners squad, offers the first real chance for fans to see whether this new direction holds promise—or just more of the same. Taking the mound for San Francisco is none other than Justin Verlander, who is, somehow, entering his 20th major league season and still refusing to age like the rest of us. At 41, Verlander may not have the overpowering fastball that once won him Cy Young Awards, but he’s adapted with surgical precision and an expanded pitch mix. This spring, he worked on refining a sweeping curveball designed to increase horizontal movement, adding another layer of deception to an already polished arsenal. While the Mariners’ lineup features athleticism and pop, Verlander’s edge in experience and game-planning could neutralize their aggression.
The Giants are hoping that his presence in the rotation does more than just eat innings—it brings accountability and mentorship to a staff that needs both. Offensively, the Giants are banking on a more well-rounded lineup in 2025. Last season, they hit .239 as a team and struggled mightily with runners in scoring position. The addition of Adames is meant to address both issues—he brings solid gap-to-gap power, improved contact, and a disciplined approach that should stabilize the top half of the order. Surrounding him are familiar names like Michael Conforto, Mike Yastrzemski, and Wilmer Flores, who are capable of production but have lacked consistency in recent years. Thairo Estrada, who’s grown into a dependable middle infielder, will likely continue to serve as a catalyst on the basepaths. But the real x-factor for this team is whether the bench depth and younger call-ups can contribute meaningfully in the grind of the season. San Francisco isn’t loaded with stars, but if they can stay healthy and manufacture runs consistently, they’ll be far more dangerous than their middling 2024 numbers suggest. Defensively, the Giants are banking on Adames to shore up a leaky infield. Last year’s defense gave away too many outs, putting added pressure on the pitching staff. The hope is that a more stable middle infield—combined with seasoned corner defenders—can prevent the types of collapses that plagued them in tight games. In front of a sold-out home crowd and with fresh leadership behind the scenes, this is more than just Opening Day—it’s a first step toward reestablishing the Giants as legitimate contenders. For San Francisco, the window isn’t wide open, but for the first time in a while, it doesn’t feel shut either.
