Fantasy baseball analyst Dalton Del Don offers up a batch of priority waiver wire pickups to consider adding as we come to the close of Week 4.
Luke Keaschall, 1B/2B/OF, Minnesota Twins (32% rostered)
Keaschall entered the season as a sneaky prospect coming off Tommy John surgery, and he’s been highly impressive since getting called up to Minnesota one week ago. He owns a 214 wRC+ with a 2:5 K:BB ratio and most importantly he’s running wild; Keaschall has recorded the most stolen bases (five) over his first five MLB games ever. He has 74th percentile Sprint Speed and finished with 23 steals (over 102 games) last year in the minors, so this torrid pace obviously isn’t sustainable. But that number of attempts given his limited opportunities is highly encouraging for fantasy managers, and Keaschall can hit. The Twins have quickly moved him to third in their lineup, and he’s eligible at three different positions. Keaschall remains available in nearly 70% of Yahoo leagues.

Roman Anthony, OF, Boston Red Sox (28%)
Anthony still doesn’t have a spot in the Red Sox’s lineup as of now, so he’s admittedly a tougher stash in some shallower leagues. But any injury (outside of catcher) would open an opportunity for Anthony given Boston’s roster makeup. He nearly went 20/20 (in just 454 ABs) and posted a 147 wRC+ across the minors as a 20-year-old last season. Anthony’s been even better in 2025, recording a 167 wRC+ with four homers and two steals (over just 74 ABs) in Triple-A despite dealing with a sore shoulder that limited him to DH for a couple of weeks. Anthony owns a 22.3 K% and 20.2 BB% with a cartoonish 35.2 Barrel% that nearly doubles the hitter ranked second.
OOPSY projects a 119 wRC+ rest of season once the rookie is called up, and Anthony will run. He’s going to benefit from baseball’s second-best hitter’s park for lefties and eventually pay off for patient fantasy managers.

Noelvi Marte, 3B, Cincinnati Reds (16%)
Marte looked like a future fantasy star as a prospect and more than held his own (119 wRC+) over 123 plate appearances as a 21-year-old in the majors. He was then suspended 80 games for a PED violation just before the start of the 2024 season. Marte looked completely lost at the plate (46 wRC+, 3.7 BB%, 31.0K%) after returning and began 2025 in the minors. But the former top prospect performed well in Triple-A and has…
