Three top fantasy baseball prospects - Henry Bolte, Colt Emerson, Edwin Arroyo - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Targeting high-impact prospects can provide a much-needed spark to your fantasy team. Those who stashed Payton Tolle ahead of his return to the majors this spring received a massive uptick in strikeout production and a potential must-start pitcher for the remainder of the campaign.
Below, we will spotlight three of the top hitting prospects in the minor leagues, including one who recently earned their call to their respective MLB roster.
Should fantasy managers stash these high-end prospects? Let's dive in!

Henry Bolte, OF, Athletics
Current Level: AAA
Availability: 10% rostered
2026 AAA Stats: 37 G, .348/.418/.658, 7 2B, 12 HR, 17 SB
Bolte was the A's second-round pick in 2022, signing for $2 million after tearing up the prep circuit at Palo Alto High School. He has ascended up the organization's prospect rankings while progressing through the minor league system, and he's off to an otherworldly start to the 2026 season.
Bolte has been a strikeout liability in the past, but he has tapped into more power and higher exit velocities this year. His 109.6 mph EV90 ranks in the 99th percentile in Triple-A, and he's been aggressive on hittable pitches with an elite 75.7% zone swing rate. He runs incredibly well and is a constant stolen base threat who also possesses the necessary range to stay in center field long-term.
Last week, Bolte went 15-for-27 with five homers, four doubles, a triple, and nine RBI. Part of that offensive outburst included back-to-back five-hit games. He also had one walk, three strikeouts, and four stolen bases.
The 22-year-old was given the call to the majors earlier this week and is a top waiver wire add ahead of a potential breakout season.

Colt Emerson, SS, Seattle Mariners
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 33 G, .254/.345/.468, 7 2B, 6 HR, 8 SB
After a slightly sluggish start to the season, Colt Emerson has been heating up of late. In nine games this month, Emerson is slashing .300/.341/.500 with a triple, two home runs, and a steal. For the season, he's now up to six home runs and eight steals in 33 games with a .254/.345/.468 slash line.

While Emerson's contact rates have ticked down a bit this season, that's not a major concern moving forward. I still expect him to provide a solid AVG and OBP long-term. Emerson has also started twice at third base this month, which is probably the most likely path to him getting regular playing time with the Mariners in the short term.
