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's two-run home run in the first inning sparked a six-run rally for the Seattle Mariners, who triumphed 8-3 over the Toronto Blue Jays. This win secured the series victory for Seattle in a three-game set. Raleigh's ninth home run ties him for the major-league lead. Rowdy Tellez contributed a pinch-hit homer in the seventh, marking his third in the series.

Seattle's 12 hits overwhelmed the Blue Jays, despite a strong debut from Toronto reliever Paxton Schultz, who struck out eight batters. The Mariners' offensive surge was propelled by Dylan Moore's first-inning leadoff blast, followed closely by Raleigh's shot. Starter Luis Castillo lasted five innings, allowing three runs, while the Mariners recorded 18 strikeouts overall, showcasing a mixed performance against Blue Jays pitching.

Paxton Schultz made a remarkable debut for the Toronto Blue Jays, striking out eight batters over 4 1/3 innings against the Seattle Mariners, tying the major-league record for most strikeouts by a reliever in their debut. Despite the Blue Jays ultimately losing 8-3, Schultz's performance was a bright spot, showcasing his potential on the mound. Entering after starter Easton Lucas struggled, Schultz quickly found his rhythm, notably throwing a fastball that resulted in his first career strikeout against Donovan Solano.

In a whirlwind of events leading to his promotion, Schultz drove across the border from Buffalo to Toronto after being informed of his call-up due to an injury to Nick Sandlin. He signed his major-league contract just hours before taking the mound. His effective changeup and ability to maintain composure under pressure earned him praise from manager John Schneider, marking a memorable start to his MLB career. This outing also ties him with several other notable pitchers in Blue Jays history.

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.

Ronald Acuña Jr. is vocal about the different treatment he perceives from Atlanta Braves manager Brian Snitker compared to that of Seattle Mariners' Jarred Kelenic, who was thrown out for not hustling. Acuña, recovering from a major injury, hinted through social media that if he had been in Kelenic's position, he would have faced more severe consequences. This criticism followed a similar incident in 2019 when Snitker removed Acuña from a game for not running out a hit.

As Acuña makes strides in his recovery, he could potentially return to the Braves' lineup soon. The current state of the Braves' offense, featuring new leadoff hitter Alex Verdugo who has quickly adapted, raises questions about Kelenic's future with the Mariners should he fail to improve his performance.
