Although these might not all be superstars, these are prospects that have stood out early on and should be on our dynasty radar as they continue to rise up the organizational ladders. I’m going to highlight five prospects who have recently been promoted and are taking steps toward your dynasty baseball rosters. Let’s get into it.

Promoted Prospects To Watch

Nick Morabito, OF NYM

(30 GP, .396/.520/.515, 1 HR, 21 R, 10 RBI, 16 SB)

Selected out of High School 75th overall in the 2022 MLB Draft, Nick Morabito has come into his own since his first full season of professional ball in 2023. The 21-year-old stands 5’10” and has a plus hit tool paired with above-average speed and solid defensive skills. The Mets started Morabito back in Low-A St. Lucie this season and he picked up where he left off in 2023. In 24 games he slashed .397/.530/.513 with one home run, 14 runs scored, 10 RBIs, and 11 stolen bases in 15 attempts. At the plate, Morabito has an advanced eye as he walked 17.8% as well and struck out 17.8% of his 101 total plate appearances. Morabito is not a power bat by any means but batting lead-off has led to plenty of runs scored.

The Mets promoted Morabito to High-A Brooklyn where he has hit the ground running. In six games played, he is slashing .391/.481/.522 with seven runs scored, and stole five bases in six attempts. When it comes to the plate approach Morabito stays true walking and striking out 14.3% over 28 plate appearances. This is a prospect who has gone widely under the radar since the draft but it’s all starting to turn around now as Nick Morabito is currently rostered in 2% of Fantrax dynasty leagues.

Yohendrick Pinango, OF CHC

(31 GP, .318/.431/.570, 5 HR, 20 R, 19 RBI, 3 SB)

When it comes to Yohendrick Pinango he was fantastic from 2019 in Rookie Ball through 2021 where he finished the season in High-A slashing .289/.343/.381 in 24 games played. The Dr. Jekyll and Mr. Hyde that has been Pinango the last two seasons at High-A has been puzzling, to say the least, but he seems to have gotten back on track this season. In 29 games played at High-A in 2024, Pinango was slashing .340/.451/.610 with five home runs, 20 runs scored, 19 RBIs, and stole three bases in six attempts. Pinango increased his walk percentage from 9.1% in 2023 to 16.4% and lowered the strikeout rate to 12.3% in 122 plate appearances.

The Cubs saw what they needed to see to promote Pinango to Double-A where he has played just two games. If he is able to continue the hot start got off to Pinango could start rising back up dynasty rankings quickly. Currently, Yohendrick Pinango is rostered in 2% of Fantrax dynasty Leagues.

Brandon Sproat, RHP NYM

(7 GP, 6 GS, 30.1 IP, 39 K, 11.6 K/9, 0.89 ERA)

When it comes to Brandon Sproat the Mets were adamant in drafting him. So much so that they drafted him twice; once in the third round of the 2022 MLB draft before he headed back to Florida. In 2023 the Mets upped the anty by selecting Sproat in the second round where he signed but did not pitch after the draft. The Mets then sent Sproat, Nolan McLean, and several other pitching prospects selected in the draft to the new pitching lab that opened in 2023. It looks like Brandon Sproat might be one of the Mets’ latest success stories as he was dominant in his first taste of professional ball at High-A Brooklyn.

In six appearances (five starts) Sproat struck out 33 batters over 25.1 innings pitched, good for an 11.72 K/9 with a .141 average against, and finished with a solid 1.07 ERA. Sproat allowed one home run demonstrating an excellent ability to keep the ball on the ground at 62.7%.

After the sixth appearance the Mets promoted Sproat to Double-A Binghampton where he was dominant in his first outing with the Rumble Ponies. In five innings pitched Sproat struck out six allowing just three hits, no runs, and two walks. Sproat’s best offering is the fastball that tops out at 101 and sits in the 94-98 mph range paired with a devastating slider. For dynasty managers, Sproat has SP 2 upside if he can get the command and control right long term. Because of the success early and the buzz around Sproat early on he is currently rostered in 7% of Fantrax dynasty leagues.

Spencer Schwellenbach, RHP ATL

(7 GS, 38 IP, 43 K, 10.2 K/9, 2.13 ERA)

The second-round pick by the Atlanta Braves out of the University of Nebraska back in 2021 is heading up to Double-A Mississippi after a strong start to the season in High-A Rome. In his second stint at High-A Schwellenbach started six games striking out 34 batters over 32 innings, good for a 9.56 K/9 with a solid .215 average against, and finished with a 2.53 ERA. Schwellenbach did a great job limiting the walks to just 2.53 BB/9 in his 32-innings pitched while allowing just one home run. At 23 years old Schwellenbach is older for the level so the move to Double-A was warranted.

He made his debut with the Mississippi Braves going six innings while striking out nine batters, allowing just three hits, one walk, and no runs. Schwellenbach features a solid four-pitch mix headlined by the fastball coming in at 96 mph and the 86 mph slider. With a borderline plus curveball and average change up Shwellenbach has been tough to face in the lower minors. For dynasty managers, this could be an interesting prospect to watch with high strikeouts and to this point low walk rates. Currently, Spencer Schwellenbach is rostered in 11% of Fantrax dynasty leagues.

Yujanyer Herrera, RHP MIL

(6 GP, 1 GS, 24.1 IP, 38 K, 14.1 K/9, 2.22 ERA)

Milwaukee continues to develop pitching prospects well and Yujanyer Herrera came out on fire this season in Low-A Carolina. The 20-year-old right-hander stands 6’3” and 175 pounds and intimidates batters with a solid four-pitch mix. The fastball tops out at 97 mph with an excellent ride up in the zone, and the sweeping slider coming in at 87 mph is a filthy out pitch early on. Rounding out the pitch mix is a change-up and curveball, the latter is a new addition that sits in the low-80s with a sharp break-in on right-handed batters. In four appearances in Low-A Herrera struck out 27 batters over 17 innings pitched, good for a 14.29 K/9 with a fantastic .172 average against, all while finishing with a solid 2.12 ERA. Herrera was used as a piggyback starter logging an average of 4.2 innings pitched per outing.

Once promoted to High-A Herrera has been deployed two times (once as a starter) in which he struck out 11 batters over 7.1 innings pitched, good for a 13.50 K/9 with a .185 average against, and has a 2.45 ERA. The high walk rates in 2023 seem to be limited as Herrera had a 3.18 BB/9 in Low-A and currently has a 3.68 BB/9 in High-A. Herrera finds success keeping the ball on the ground when he is not striking batters out as he had a 54.8% GB% prior to the promotion. In addition to the excellent ground ball rate, Herrera has yet to allow a home run something he has been successful in throughout his young career. Currently, Yujanyer Herrera is rostered in 2% of Fantrax dynasty leagues making him an excellent deep league stash.
