As the MLB season progresses into Week 16, fantasy baseball managers should focus on the waiver wire for potential category boosters. Colt Keith of the Detroit Tigers is making waves, batting leadoff and bringing in a solid performance with eight home runs and 43 runs. Meanwhile, J.P. Crawford from the Seattle Mariners and Angel Martinez of the Cleveland Guardians are providing consistent run support with impressive batting averages. For those seeking home runs, Noelvi Marte from the Cincinnati Reds is showing promise after recovering from injury, complemented by Jorge Polanco's power for the Mariners.

In terms of RBIs, Evan Carter from the Texas Rangers has a knack for driving in runs, while Baltimore's Ramon Laureano is making a case for increased playing time. Speedsters like Chandler Simpson from the Tampa Bay Rays and Sal Frelick from the Brewers are also noteworthy for stolen bases, despite Frelick's recent hamstring issue. For those in need of batting average boosts, Alec Burleson of the St. Louis Cardinals and Jung Hoo Lee of the Giants are viable options to consider as they continue to show solid performances.

The Seattle Mariners remain competitive in the American League West, positioned for a potential playoff berth despite a recent slump, losing 15 of their last 23 games. Their struggles have prompted concerns about their offseason strategy, which many deem lacking, particularly in securing impactful players like Alex Bregman or Pete Alonso. The Mariners opted for minimal changes, relying on a platoon at first base and hoping to revitalize their offense before the trade deadline.

Cal Raleigh has emerged as a key performer for the Mariners, yet the team’s overall offensive metrics remain concerning, placing them near the bottom in OPS rankings. While there is still time to turn the season around, the Mariners must make strategic moves, especially as they approach the trade deadline.

In a pivotal matchup on June 13, the Seattle Mariners outperformed the Cleveland Guardians, winning 7-2, highlighted by a decisive four-run seventh inning. Randy Arozarena's timely RBI single initiated the scoring surge, allowing the Mariners to break a tie. Rowdy Tellez and Jorge Polanco contributed significantly with a double and a home run each. The Mariners secured just their second win in ten games, snapping a three-game losing streak. Despite back-to-back homers from Nolan Jones and Steven Kwan for the Guardians, Cleveland has struggled, losing six of their last eight games. Mariners pitcher Carlos Vargas earned the victory, while Guardians' Gavin Williams had a challenging outing.
