Big Hype Prospects: Triantos, Tiedemann, Roby, Muncy, Pauley

After one week of play in the Arizona Fall League, several of the under-the-radar players we featured last week are off to strong starts. Heading the charge is Jakob Marsee whose 1.725 OPS leads the league. He’s one of five hitters with a pair of dingers and leads with six extra base hits. He’s recorded four walks to two strikeouts and added four stolen bases. Damiano Palmegiani is also among the top ten hitters while Carter Baumler arguably turned in the best appearance among the pitchers. He went three frames and recorded seven strikeouts.

Let’s see who else merits a look.

Five Big Hype Prospects

James Triantos, 20, 2B/3B, CHC
(A+/AA) 363 PA, 4 HR, 16 SB, .287/.364/.391

Triantos spent much of the 2023 campaign in High-A. My contacts have long liked the 2020 draftee as a breakout candidate, but his in-game power output remains below expectations. There’s late bloomer talk as a result. Bear in mind, we’ve grown a bit spoiled with precocious players who aren’t yet of legal drinking age. On the defensive side, there’s are concerns he won’t stick at second base. His bat might not work in a corner role. Triantos has a 1.230 OPS in 16 AFL plate appearances.

Ricky Tiedemann, 21, P, TOR
(CPX/A/AA/AAA) 44 IP, 16.77 K/9, 4.70 BB/9, 3.68 ERA

One of the top prospects in the AFL, Tiedemann is drawing extra work after managing only 44 regular season innings. Those regular season frames were among the best in the Jays system – he led their entire farm in several ERA estimators. The bulk of the action came in Double-A where a high walk rate, BABIP, and low left on base rate led to a 5.06 ERA. Tiedemann is a candidate to make the 2024 Blue Jays, but it’s also likely he’ll have his workload carefully managed. Role: tbd. Through one AFL start, he worked five innings and allowed one run on three hits and three walks with seven strikeouts.

Tekoah Roby, 22, SP, STL
(AA) 58.1 IP, 10.6 K/9, 2.3 BB/9, 4.94 ERA

Like Tiedemann, Roby is getting extra work in the AFL due to missed time during the regular season. After being traded at the deadline, the right-hander pitched impressively in four starts for the Cardinals. His AFL outing consisted of three shutout innings. He allowed one hit with five strikeouts. He features a repertoire of four above-average pitches led by an excellent curveball. FanGraphs drops a Hunter Brown comp. Personally, I smell a whiff of Aaron Nola. He’s trending high floor, high ceiling as a prospect.

Notably, the Cardinals have struggled to finish their pitching prospects. Their matriculated pitchers like Zack Thompson and Matthew Liberatore often show little understanding of pitch design. Even Johan Oviedo took an instant step forward upon leaving the Cardinals. It’s unclear if this is a persistent organizational failure or pure happenstance.

Max Muncy, 21, SS, OAK
(A+/AA) 545 PA, 10 HR, 13 SB, .275/.353/.411

While most facets of his game remain a work in progress, Muncy appears to be trending toward some form of big league future. The 2021 first-rounder made considerable strides with his contact rate during the 2023 campaign. Scouts mostly view him as a utility guy in the making, although there’s still plenty of time for him to develop the game power and defensive consistency necessary to serve as a regular. His AFL season is off to a splashy start with a 1.009 OPS in 18 plate appearances.

Graham Pauley, 23, 3B, SD (AA)
(A/A+/AA) 551 PA, 23 HR, 22 SB, .308/.393/.538

Since their minor league affiliates skew hitter-friendly, the Padres have a knack for producing exciting-looking position players who fade on the approach run to the Majors. Success stories like Ty France tend to be the exception rather than the rule. Pauley didn’t have much of a draft pedigree when he was selected in 2022, but he’s since developed a reputation as a guy who gets the job done despite unconventional hitting mechanics. A left-handed hitting corner fielder with an extreme pull approach, he might reach the Majors as a carefully managed platoon man – the kind of player favored by teams like the Brewers, Rays, and Giants.

Three More

Adam Seminaris, MIL (24): Acquired in the Hunter Renfroe trade, Seminaris is Rule 5 eligible this offseason. He’s playing for a roster spot in Milwaukee or elsewhere. The soft-tossing southpaw is off to a good start in the AFL. He worked four scoreless innings with one hit and seven strikeouts.

Jackson Jobe, DET (21): One of the fastest-rising pitching prospects, Jobe is rounding out a season that saw him throw about 20 fewer innings than 2022. Since Jobe could be a midseason consideration for the Tigers, his workload is of obvious concern. His AFL debut consisted of four shutout innings with two hits, two walks, and four strikeouts.

Chase DeLauter, CLE (22): DeLauter is the current AFL RBI leader. Like many a Guardians outfield prospect, DeLauter rarely whiffs. His awkward-looking swing has no analogs in the Majors. It looks a bit like a stumbling-drunk Alek Thomas. While credited with plus raw power, it’s unclear if his bat will play against stiffer competition.
