Diamond Diplomas: Gone Fishing

Prospects Live May 12, 2026

Welcome to Diamond Diplomas! Whether you compete in the deepest of dynasty leagues or want to win the office redraft title, Prospects Live has you covered. Before we dive in, here is a quick overview of the tier system. Both the hitter and pitcher lists feature three “tiers” of prospects. These tiers loosely correspond to the PLive Dynasty prospect rankings of these players relative to one another, but the author (yours truly) will often place and move names around to more accurately reflect both their real-time dynasty value and their potential for major league fantasy production in 2026. For a full breakdown of the tier system used to prioritize players, take a look at the first article in this season’s series here:

Report Card

Called Up :

Ryan Waldschmidt, OF (ARI): The Diamondbacks’ top prospect did not have to wait long for his MLB debut after starting the year off strong in Triple-A. The former first-rounder earned a call-up thanks to an .877 OPS with three homers and six steals in 34 games so far this year. Waldschmidt should continue seeing regular playing time in the outfield for Arizona, and he has enough power and speed upside to warrant pickup consideration even in shallow redraft formats.
A.J. Ewing, 2B/OF (NYM): Late Monday night, news broke that the Mets decided to call up Ewing from Triple-A after giving him just twelve games at the highest level of the minor leagues. The 21-year-old’s quick second promotion comes as little surprise, however, as he hit .326 with as many walks (5) as strikeouts (5) in that time. Though he is capable of holding down the keystone, Ewing will likely see most, if not all, of his MLB time in the outfield for the foreseeable future. His speed and hit tool should translate rather smoothly to the majors, giving him immediate redraft appeal for managers seeking steals and a batting average boost.
Spencer Jones, OF (NYY): At long last, the sport’s most polarizing prospect has reached the Show. Jones joined the Yankees last Friday, and he figures to play a prominent role in their everyday outfield until Jasson Domínguez or Giancarlo Stanton return from injury. His power + speed upside is among the best in baseball, but the developmental trajectory of his subpar hit tool will ultimately determine his MLB value.
Henry Bolte, OF (ATH): Speaking of guys who run fast and hit the ball hard, Bolte’s MLB debut is also imminent. While his contact profile has improved in 2026, the young outfielder does need to rectify his 58.1% groundball rate in order to make the most of his impressive physical tools. He had been one of the hottest bats in the minor leagues prior to this promotion; however, he deserves watch-list status at a minimum for redraft.
Robby Snelling, P (MIA): Perhaps the biggest name in a week of overdue call-ups, Snelling at long last is getting some run in the rotation for Miami after having logged nearly 100 innings in Triple-A over the past couple of seasons. His debut start was a decent five-inning effort, though he did display some rookie jitters by issuing four walks. The southpaw has frontline upside, however, and should be rostered and started in just about every fantasy format moving forward.
Kendry Rojas, P (MIN): Rojas made his second big league appearance last weekend and put together a strong showing by striking out five over three and 1/3 innings of one-run ball. Given the Twins’ injury issues, Rojas will probably remain with the team for the time being, but will still be operating in his current long-relief role, which limits his fantasy upside in the short-term.
Franco Aleman, P (CLE): Aleman was last week’s Sleeper Pick in this article series, so the Guardians must be Prospects Live subscribers! Cleveland brought the tall righty up to the majors to reinforce their bullpen, and he delivered two shutout innings on Sunday in his first MLB outing. Though he only holds fantasy relevance in deep dynasty formats for now, Aleman has the stuff to earn higher leverage looks in due time.

Locked In :

Kaelen Culpepper, SS (MIN): This makes back-to-back Locked In appearances for Culpepper, as the former Kansas State star has continued to swing a hot bat in Triple-A. Last week, he drove in nine runs and crushed two homers to push his season OPS up to a nice, round .800 mark. Continued excellence will likely prompt the Twins to bring him up to the majors before the All-Star break at the latest.
Kahlil Watson, OF (CLE): More on him later, but Watson has been flashing glimpses of his first-round pedigree lately for Cleveland’s Triple-A affiliate. The now-outfielder tallied two home runs and four steals last week, showcasing the toolsy athleticism that tempted Miami into drafting him 16th overall back in 2021. Five years later, he now finds himself on the doorstep of the majors.
Edwin Arroyo, SS/2B (CIN): Another post-hype name, Arroyo is having something of a renaissance season. The 22-year-old’s three home runs last week brought his season total up to seven, and his wRC+ up to 152. There is not a lot of room in the Reds’ infield, but Arroyo’s decent pop and speed could make him an intriguing fantasy asset in deep dynasty leagues.
Kade Anderson, P (SEA): Anderson’s case to be seen as the sport’s top pitching prospect gets stronger by the week. After another five and 2/3 innings of one-run work, the lefty now boasts an immaculate 0.60 ERA and 0.67 WHIP through the first six starts of his minor league career. He has little left to prove against amateur opposition and should be getting MLB outs for Seattle soon.
Brody Hopkins, P (TB): Hopkins made two starts last week, and both outings highlighted his strengths and weaknesses as a pitching prospect. He tossed eight shutout innings, striking out 10 batters, but six free passes continued a concerning uptick in his walk rate this season. He will likely need to dial in his command a bit before Tampa turns to him for rotation help.
Jack Wenninger, P (NYM): For the second straight week, Wenninger pitched his way into Locked In status, this time courtesy of a six-inning start in which he allowed no runs and struck out five hitters. If the Mets continue to struggle and end up trading away any of their veteran starters, look for Wenninger to see some time in the big league rotation this season.

Dropped Off :

Jaxon Wiggins, P (CHC): Though initially the hope was that Wiggins’ time on the injured list would be brief, the righty remains shelved with the same right elbow issue that sidelined him back in mid-April. He will need a full ramp-up once cleared, so do not expect Wiggins to debut in MLB any time soon.
