The Seattle Mariners face a setback as Dylan Moore is placed on the injured list due to right hip inflammation. Moore, a Gold Glove utility player, has contributed significantly across four positions this season, boasting a .286 batting average with six home runs and nine RBIs in 23 games. Meanwhile, Samad Taylor has been called up from Triple-A Tacoma to fill the roster gap, showcasing impressive stats, including a .321 average and a .950 OPS in the Pacific Coast League.

Furthermore, the Mariners have transferred Gregory Santos to the 60-day injured list, a necessary move to accommodate Taylor on the 40-man roster. Santos previously had a 5.14 ERA during his appearances this season, indicating the team's need for stronger pitching options. With Moore's absence, Seattle will look to bolster its lineup as they aim for success in the AL West.

As the fantasy baseball season progresses into Week 5, savvy managers should focus on trading opportunities to enhance their rosters. Target players like Sandy Alcantara of the Miami Marlins, who despite a slow start, possesses the potential to regain his Cy Young form. Similarly, Brandon Nimmo from the New York Mets, currently underperforming, has a solid track record and is positioned for a rebound as part of a strong lineup.

On the flip side, players like Andrew Heaney of the Pittsburgh Pirates, who have recently posted exceptional numbers, may be overvalued and should be sold while interest is high. Likewise, Dylan Moore of the Seattle Mariners, while versatile, has stocks that might not sustain his early success. Trading him now could capitalize on his inflated value.

Week 4 of the 2025 MLB season brings a spotlight on players who are heating up and those who might be fantasy frauds. A notable buy is Trevor Story of the Boston Red Sox, who is hitting .318 with five homers and six steals. Despite his injury history, his early-season metrics indicate a potential breakout, making him a valuable addition for fantasy managers.

On the pitching side, Tyler Mahle of the Texas Rangers has turned heads with 25 scoreless innings, showing promise post-Tommy John surgery. Meanwhile, Seattle's Dylan Moore, despite a hot streak, is labeled a sell due to his historically low batting average. Other players worth noting include Carson Kelly and Andrew Abbott, both of whom are also trending upwards this week.

Cal Raleigh propelled the Seattle Mariners to an 8-3 victory over the Toronto Blue Jays with a two-run homer in the first inning, marking his ninth of the season and tying him for the league lead with Tyler Soderstrom. The Mariners exploded for six runs in the first, aided by Dylan Moore's leadoff homer. The loss spoiled the major-league debut of Blue Jays reliever Paxton Schultz, who struck out eight but was ultimately part of a bullpen effort that couldn’t stop Seattle’s 12-hit attack.

Rowdy Tellez contributed a pinch-hit two-run shot in the seventh inning, capping a strong series with three homers. Luis Castillo earned the win, allowing three runs over five innings, while the Blue Jays' Easton Lucas struggled, yielding six runs in his short outing. This win secured the series for Seattle, improving their record to 12-10, while Toronto fell to the same mark. Up next, the Blue Jays face the Astros and Yankees, with Kevin Gausman slated to start against Hunter Brown.

In Week 4 of the 2025 MLB season, fantasy managers should consider making strategic waiver wire pickups for infielders. Dylan Moore of the Seattle Mariners is highlighted for his impressive start, hitting .308 with significant contributions in home runs and stolen bases, making him a solid candidate despite concerns about his past performance. Minnesota Twins’ Carlos Correa is also a potential add, with signs of improvement following a sluggish start. Meanwhile, Athletics’ prospect Nick Kurtz shines in the minors, boasting a .329 average and leading the league in home runs, making him a valuable stash for deeper leagues.

Additionally, Pavin Smith from the Diamondbacks and Baltimore’s Ryan O'Hearn are emerging as strong options, providing consistent batting averages and promising potential against favorable pitching matchups. With the season already underway, making informed decisions on these waiver wire additions could significantly impact fantasy teams moving forward.
