As the 2025 MLB season heats up, Week 4's fantasy baseball waiver wire offers several intriguing outfielders worth considering for your roster. Tyler Fitzgerald of the San Francisco Giants has been on fire, showcasing a .444 batting average with two home runs and six RBIs in his last seven games. His dual eligibility at OF, 2B, or SS makes him a valuable pick-up for those looking to capitalize on his hot streak.

Similarly, Sal Frelick from the Milwaukee Brewers is excelling with a .319 batting average and five steals, making him a solid volume play. Meanwhile, Houston Astros rookie Cam Smith is building on his momentum, having recently notched his first multi-homer game. For deeper leagues, Austin Hays and Heston Kjerstad are generating buzz with power potential, while Mike Yastrzemski offers a temporary boost due to favorable matchups.

As the 2025 season approaches, bat speed statistics provide valuable insights into players' offensive potential. Notably, Jesse Winker of the New York Mets has increased his bat speed by 6.6 mph, reaching an impressive 76.1 mph. This improvement places him among the top ranks in the league, although his early-season performance has been lackluster, indicating the need for patience. Meanwhile, Junior Caminero of the Tampa Bay Rays boasts the highest average bat speed at 80.3 mph, which has significantly boosted his power potential. Brendan Rodgers from the Houston Astros also shows promise with a 3.7 mph increase, hinting at a healthier season. However, not every player with increased bat speed will find immediate success; factors such as contact point adjustments and swing decisions also play critical roles.

As the MLB season progresses, the Baltimore Orioles face lineup shifts due to Gunnar Henderson's intercostal injury, giving Jackson Holliday and Jorge Mateo opportunities at shortstop. Colton Cowser's thumb fracture opens a door for Heston Kjerstad, who will likely see regular playing time against right-handed pitchers. Meanwhile, the Boston Red Sox’s Triston Casas is expected to secure a full-time role despite a rocky start, while Wilyer Abreu impresses in his limited appearances.

The New York Yankees are experimenting with leadoff hitters, with both Austin Wells and Paul Goldschmidt having success. The Tampa Bay Rays' Curtis Mead showed promise on Opening Day but faced lineup uncertainty with injuries. The Toronto Blue Jays are giving Andres Gimenez an untraditional cleanup spot, and the Chicago White Sox are mixing up their leadoff approach with Miguel Vargas. The Cleveland Guardians’ Kyle Manzardo is thriving in the early season, further solidifying his role.

Jordan Westburg showcased his talent with a standout performance, hitting two home runs during the Baltimore Orioles' 9-5 victory over the Toronto Blue Jays. Alongside Colton Cowser, who also homered in the first inning, Westburg's contributions helped the Orioles secure an early lead and maintain momentum throughout the game.

Key offensive plays included a four-run inning ignited by Gary Sanchez's sacrifice fly and capped by Ramon Urias's three-run double. Baltimore’s pitching staff, led by Dean Kremer, managed to hold off Toronto's threats, despite a two-run homer from Andres Gimenez. The Blue Jays struggled with Max Scherzer's early exit due to injury and a faltering bullpen, allowing the Orioles to capitalize and control the game.

The 2025 MLB season is officially underway, with predictions for all 30 teams aimed at stirring the pot. Corbin Carroll of the Arizona Diamondbacks is expected to join the elite 20-triple club, while the Athletics, despite a rough past season, are projected to be surprisingly competitive and sit in a postseason spot by July. In Atlanta, young catcher Drake Baldwin could take over the starting role from Sean Murphy due to an injury, potentially reshaping the Braves’ roster dynamics.

Heston Kjerstad may be traded by the Baltimore Orioles for a starting pitcher as he remains blocked in the current lineup. The Red Sox are boldly expected to hit a grand slam on Opening Day after failing to do so last season. Star prospect Pete Crow-Armstrong could earn an MVP vote, and the White Sox might avoid the worst record in the league despite a dismal outlook.

The Cincinnati Reds hope Elly De La Cruz will reduce his strikeouts, while the Guardians might finally see two outfielders hit 20 home runs in a season. The Rockies and Tigers are eyeing significant strides, while the Astros hope Jose Altuve can adapt to left field. In Kansas City, Bobby Witt Jr. is predicted not to lead the Royals in home runs, a bold assumption given his star potential.
