5 Prospects To Watch – Rankings 301-400

Jansel Luis, SS/2B ARI- Ranked 306

(62 GP, .269/.335/.441, 7 HR, 37 R, 27 RBI, 16 SB)

If you are looking for a prospect to buy now that could gain a ton of value look no further than Jansel Luis. Overall the first season state-side went well for Jansel Luis as he split time between the complex league and Low-A Visalia. Across 25 games at the complex Luis slashed .297/.381/.495 with three home runs, 18 runs scored, 12 RBIs, 9 stolen bases with a 8.6% walk rate, and a 14.3% strikeout rate in 105 plate appearances. This was on par with what we saw from Jansel Luis in 2022 while in the DSL so it makes sense that the Diamondbacks sent the 18-year-old to Low-A Visalia to finish off the season. In 36 games played with the Rawhide Luis slashed .257/.310/.417 with four home runs, 19 runs scored, 15 RBIs, and seven stolen bases with a 5.2% walk rate and 22.6% strikeout rate over 155 plate appearances.

Despite the average and OBP not being as strong as we have seen in the DSL and CPX league, there was a lot to like with Jansel Luis with the bump to Low-A Visalia. Of Jansel Luis’s 37 hits with the Rawhide 12 of them were extra base hits with three of those coming as triples. So you see the speed play up while he continues to show above-average power at just 18. Standing at 6’0” and 170 pounds there is still some room for muscle so a 15-plus home runs season in 2024 is not out of the question. The average and OBP should come back up as he gets familiar with advanced pitching as Luis is a high-contact hitter naturally.

Cade Kuehler, RHP ATL- Ranked 338

(2 GS, 7 IP, 8 K, 10.29 K/9, 0.00 ERA)

With a championship-caliber team established on the batter’s side in Atlanta, it’s no surprise that the Braves have gone into the MLB draft with pitching in mind. This past draft we saw the Braves take Hurston Waldrep in the first round who in his own right has massive upside. But let’s not sleep on the Braves second-round selection Cade Kuehler who was drafted out of Campbell University. In his final season with the Campbell Camels Kuehler started 13 games striking out 91 batters over 73 innings pitched good for an 11.2 K/9 and finished the season with a 2.71 ERA. The Braves only had Kuehler pitch seven innings across two starts, in which the right-hander struck out eight batters and finished with a 0.00 ERA.

What stands out with Cade Kuehler is his pitching arsenal he can go to and morph as he sees fit. There is the four-seam fastball that sits in the mid-90s and tops out at 99 mph but he will mix in a two-seam fastball in specific situations. Next is the slider that typically sits around 85-86 mph with solid break but Kuehler will at times limit the break creating more of a cuter against lefties. The curveball has a solid break and depth to it and plays off the slider speed-wise at 82 mph. If that wasn’t enough Kuehler will throw a change-up and splitter both around 84 mph with solid tumble and fade. All of these offerings are helped by Cade Kuehler’s high spin rates which I believe could make him one of the most underrated pitchers in this year’s FYPD.

Jeffry Rosa, OF NYM- Ranked 365

(44 GP, .277/.400/.669, 15 HR, 35 R, 39 RBI, 1 SB)

What a difference one season can make for some of these international prospects who sign so young. For Jeffry Rosa playing at 17 years old in 2022, the results just were not there. Rosa slashed .216/.315/.371 with just three home runs, 11 runs scored, and three stolen bases in 33 games played oh, and a 42% strikeout rate. Fast-forward to last season in the DSL where Jeffry Rosa a year older and considerably bigger than the year prior put together a solid bounce-back season. In 44 games played Rosa slashed .277/.400/.669 with a league-leading 15 home runs, 35 runs scored, 39 RBIs, and one stolen base. The gains are not just in the surface-level stats Rosa improved his walk rate from 6.3% to 8.8% while substantially lowering his strikeout rate to 25.3% in 182 plate appearances.

Obviously, with Rosa leading the DSL in home runs there is bound to be plus-power to be had. In addition to the home run output though Rosa hit 13 doubles bringing his extra-base total to 28 out of his 41 total hits. The line drive rate jumped from 19.1% to 28.1% in 2023 further solidifying Rosa’s gains year over year. To me, this is an exciting prospect to stash in deeper dynasty leagues as I’m sure the Mets will start Rosa off in Low-A Port St Lucie where we can see if he will continue to improve and start climbing at 19 years old.

Trey Dombroski, LHP HOU- Ranked 372

(26 GP, 15 GS, 119 IP, 148 K, 11.19 K/9, 3.71 ERA)

Houston has always found a way to be successful with their drafts by going after college talent and having the player development to get the most out of them. Trey Dombroski was selected in the fourth round of the 2022 MLB draft out of Monmouth University where he started 15 games and pitched to a 3.13 ERA with 120 strikeouts in 95 innings pitched (11.4 K/9). Once again a gem that’s doing the same thing in professional ball as we saw from Dombroski in Low-A Fayetteville in 2023. Across 26 appearances (15 starts) Dombroski pitched 119 innings with the Woodpeckers striking out 148 batters that’s good for an 11.19 K/9. Dombroski did that all while walking just 2.72 BB/9 with a .214 average against and finished the season with a 3.71 ERA.

More credit to the Astros where it is due, they do a fantastic job drafting pitchers who are breaking ball pitchers but can locate an average fastball well. Dombroski’s fastball sits around 88 mph and only tops out in the low 90s this plays up with an 82 mph change-up that has solid fade so location is key for him. The money-making pitches are the 78 mph sweeping slider and the 75 mph curveball that has a solid break. Going into his age 23 season Dombroski should be pushed starting the season in High-A Asheville and could see Double-A Corpus Christi by mid-season with a strong start to the year.

Braxton Ashcraft, RHP PIT- Ranked 394

(19 GS, 52.2 IP, 63 K, 10.8 K/9, 2.39 ERA)

The Pittsburgh Pirates are piecing together a rotation currently in the major leagues and with the farm system light on pitching prospects (except Skenes, Chandler, and Solometo) What else can we expect? Two names that stand out to me are Thomas Harrington and Braxton Ashcraft. Braxton Ashcraft has largely flown under the radar in dynasty leagues currently going into his age 24 season and more than likely at least starting the season in Double-A Altoona. In 2022 Ashcraft had Tommy John surgery missing the entire season and had workload restrictions in 2023 while making stops in Low-A, High-A, and finishing in Double-A. Braxton Ashcraft was solid with 63 strikeouts in 52.2 combined innings pitched good for a 10.8 K/9 across 19 games started.

What impressed me most about Ashcraft’s season was the 1.9 BB/9 in all three stops . As most dynasty managers know the command can sometimes be the last to come back with pitchers coming off Tommy John. There is a four-pitch mix with Aschraft in a high 90s fastball that has high spin rates creating ride-up in the zone. The high spin rates help both his slider which has a short-cutting break to it that comes in around 87 mph whereas the curveball sits in the low 80s and has a solid break. There is a change-up that Ashcraft throws on occasion but it’s not something he goes to frequently. To me, this could be a solid back-of-the-rotation arm that has the pitch mix to be above average with the spin rates. This makes Braxton Ashcraft a solid pickup for dynasty leagues with little to no cost to acquire.
