5 More Underrated Dynasty Fantasy Prospects For 2026

Last week, we identified 13 underrated pitchers and nine underrated hitters with underlying traits to target for fantasy in 2026. But why stop there? This week, we’re presenting a couple more hurlers who didn’t quite make the cut but still have compelling stuff, and a few more batters with the desirable Statcast traits that may suggest better future run production compared to their surface-level stats.

Pitchers

Yoel Tejeda Jr., RHP, Nationals

• FF (40%) 52
• SL (17%) 54
• SI (16%) 56
• SW (15%) 50
• CH (11%) 50
• Ball% 36%

The Nationals’ 2024 14th-rounder ranked just outside their Top 30 entering the season. By June, the Florida State product slotted in at No. 25. Tejeda tossed 78.2 innings for Low-A Fredericksburg, then earned a promotion to High-A Wilmington where he had a 9.72 ERA in two starts.

Despite the mediocre surface numbers, Tejeda has a unique starter’s arsenal. As expected, the 6-foot-7 righty has over seven feet of extension from a low slot. That helps his 94 mph fastball play up and get over 32% chases with 13 inches of tail. His 86 mph slider elicits above-average whiffs and chase. He also has a sweeper with a foot of horizontal break and a changeup that has 9 mph separation from his fastballs. In other words, his entire five-pitch mix grades average or better and he posted a respectable 36% ball rate. Don’t be surprised if he is in the conversation for a spot in the Nationals rotation in 2027.

Ramon Marquez, RHP, Phillies

• FF (54%) 49
• CH (24%) 66
• SL (22%) 58
• Ball% 35%

Marquez ranked No. 18 in Baseball America’s Florida Complex League rankings, so he might not be too far under the radar for Baseball America subscribers. The 19-year-old threw 38 FCL innings with a 30% strikeout rate and 7% walk rate before earning the promotion to Low-A Clearwater, where he added another 17 innings with a 31% strikeout rate.

He primarily leans on a 94 mph sinker with 15 inches of tail. It’s an average pitch now, but should gain another couple ticks as he enters his early 20s. Marquez’s bread-and-butter changeup had the eighth-highest Stuff+ in the minors this year. Hitters chased it at an absurd 62% rate and it has a 13 mph velocity separation and 3 degree VAA separation from the fastball. The teenager’s 85 mph slider also grades as plus with a 47% chase rate. Marquez’s repertoire of starter traits has already established a high floor.

Hitters

Duce Gourson, 2B, Pirates

A ninth-rounder in 2024 out of UCLA, Gourson was known as a fringy defender with solid on-base skills but without a clear carrying tool. That held true in his professional debut that year. He displayed above-average swing decisions, average contact and maximized his literally average 101.6 mph 90th percentile exit velocity with a 17% barrel rate.

Those skills carried over to 2025. Gourson had above-average contact and in-zone contact rates, while chasing at a rate one standard deviation less than the rest of the league. The big difference? Gourson has really added more juice, raising his 90th percentile exit velocity to 105 mph with a maximum exit velocity of 112 mph. All that came with an absurd 23% barrel rate.

To put that into context, let’s compare Gourson’s 22-year-old season in Double-A with another 22-year-old with below-average defense, yet enjoyed a breakout MLB season: Nationals outfielder Daylen Lile.

Name	Age	PAs	Con%	z-Con%	90th EV	Max EV	Chase%	Barrel%
Duce Gourson	22	166 A+/226 AA	74%	83%	104.6 mph	112 mph	21%	23%
Daylen Lile	22	94 AA/119 AAA	77%	84%	104.5 mph	110 mph	28%	23%

From Gourson’s surface stats, RoboScout projects a 100 wRC+, .245 average, .315 on-base percentage with 15 homers and 20 steals. Based on the underlying stats, a Daylen Lile-type profile might be more attainable than we think.

Hyun Seung Lee, 3B/SS, Pirates

When Lee signed for $160,000 in the Pirates’ 2025 international class, the 6-foot-1, 176-pounder arrived in pro ball with projectable power and a chance to stay in the infield, though likely not at shortstop. He showed an excellent blend of Statcast data in his Dominican Summer League debut, especially for someone who was 17 for the entire season.

Here is how Lee compared to Edward Florentino’s 2024 DSL data (at 17 years old):

Name	Age	Con%	z-Con%	90th EV	Max EV	Chase%	Barrel%	xwOBA
Hyun Seung Lee (2025)	17	79%	86%	101.0 mph	109 mph	18%	19%	.343
Edward Florentino (2024)	17	76%	86%	103.1 mph	110 mph	19%	14%	.350

Let’s be clear: We are not suggesting Lee will be the next Pirates breakout prospect in the same mold of Florentino, who cracked Baseball America’s Top 100 a year later. That said, Florentino’s breakout wasn’t much a surprise when revisiting his 2024 Statcast data in retrospect. Their data is comparable–and excellent for their level and age–and Lee could be a big breakout in 2026.

Juan Ortuno, UTIL, Brewers

The Brewers have obviously had a lot of success on the international market recently. The 18-year-old Ortuno could be next. Prior to 2025, Baseball America earmarked him as someone to know outside Milwaukee’s Top 30 Prospects. The 5-foot-8 righthanded hitter showcased contact skills and plate discipline offset by minimal power projection, as shown by his 96 mph 90th percentile exit velocity and 99 mph max exit velocity in 2024.

That power took a big step forward in 2025. He raised his 90th percentile exit velocity to 102 mph and his max EV to 109 mph. All the while, he made above-average contact and his swing decisions remained better than average. Even more encouragingly? Ortuno raised his barrel rate from a well-below-average 5% in 2024 to a better-than-average 14% in his 105 plate appearances in 2025.

With excellent on-base skills for his age and increasing ability to make damage on contact, Ortuno might be the next product of the Brewers’ international prospect factory to make his mark on dynasty leagues.
