As the 2025 MLB season reaches the All-Star break, fantasy baseball managers are scouring the waiver wire for unheralded hitters ready to break out. This week’s focus is on four players who have been on a tear lately and could be available for a fair price, particularly in deeper leagues.

Andrew Vaughn, recently acquired by the Milwaukee Brewers, is making waves with an impressive .429 batting average and 1.500 OPS over the last two weeks, hitting two home runs and driving in 10 RBIs. His hard contact rate indicates potential for further success, especially while filling in for the injured Rhys Hoskins.

Next is Angel Martinez from the Cleveland Guardians, who boasts three home runs and nine RBIs in his last 14 days, though his overall batting average remains a concern. The young player has shown flashes of power but struggles with plate discipline, making him a risky pickup.

Harrison Bader of the Minnesota Twins is another candidate, delivering a .296 average and 1.086 OPS, along with four home runs. His improved plate discipline and hard contact figures suggest he might be worth a deeper league spot.

Finally, Kyle Higashioka, the Texas Rangers' backup catcher, has enjoyed a hot streak, hitting .355 with three home runs over the past two weeks. However, his limited role and advanced age might temper what’s considered a short-term gain.
