Big Hype Prospects: Gasser, Mead, Vientos, Frelick, Horton

Big Hype Prospects returns with a peek at the upper minors. Let’s get down to business…

Five Big Hype Prospects

Robert Gasser, 24, SP, MIL (AAA)
90.1 IP, 10.86 K/9, 3.49 BB/9, 4.18 ERA

One of the best pitching prospects remaining in Triple-A, Gasser could find his way into the Milwaukee rotation by the end of the season – if not sooner. Presently, the weak links are Colin Rea and Adrian Houser. Brandon Woodruff is nearing a return to oust one of those swingmen. Gasser is a southpaw with unusual arm action, but the Brewers pitching development staff specializes in the bizarre and grotesque, so Gasser could scarcely be in a better system for his particular brand of pitching. While he doesn’t have visually impressive stuff, the whole repertoire plays up due to plus command. Gasser might have some issues with right-handed batters.

Curtis Mead, 22, 3B, TBR (AAA)
173 PA, 3 HR, 2 SB, .311/.376/.497

The 2023 campaign hasn’t gone Mead’s way. Between missed time and a slow start, the powerful corner-man has only three home runs. Lately, he’s caught fire to the tune of .431/.493/.677 over his last 75 plate appearances, with nine walks and four strikeouts. While he has only one home run during this hot streak, Mead also swatted nine doubles and two triples. Over-the-fence results will come before long. In the meantime, Mead is swinging a big stick with the sorts of exit velocities associated with MLB regulars (89.4-mph average, 109.5-mph max).

Mark Vientos, 1B/3B, 23, NYM (MLB)
(AAA) 264 PA, 16 HR, .307/.386/.614

The Mets recently recalled Vientos despite mediocre performance on the farm, as Vientos has hit .264/.316/.472 (90 wRC+) in 57 Triple-A plate appearances since the start of July. He thrived in the minors earlier in the season and certainly deserves an extended look with the retooling Mets. Vientos presents a complicated evaluation, as his positives include plus discipline, premium raw power, and exciting in-game exit velocities. However, scouts point out issues with his swing which could prove exploitable. In 99 career MLB plate appearances, Vientos is batting just .189/.253/.267 despite excellent exit velocities (93.3-mph average, 114.9-mph max). Those are basically the exact same EVs as Juan Soto and MJ Melendez. The Melendez comp is interesting, as the young Royals slugger is having a rough season due partly to swing-and-miss issues and partly to an expansive home venue. Vientos faces similar challenges with his swing and ballpark.

Sal Frelick, OF, 23, MIL (MLB)
(AAA) 183 PA, 2 HR, 8 SB, .237/.333/.342

Recently promoted to Milwaukee, it is hoped Frelick can become a top-of-the-lineup sparkplug. He’s known for discipline and a high rate of contact. He’s also not a particularly impactful hitter. Frelick connects with the same sort of oomph as Whit Merrifield and Steven Kwan. In fact, Kwan isn’t a bad comp – they’re both 5’9’’ left-handed hitting center fielders who fit better defensively in a corner. Frelick has a better chance to stick in center while at the plate, Kwan has superior feel for contact. The end result might wind up in the same neighborhood – a no-doubt Major League starter who nonetheless fits awkwardly within the current roster-design meta.

Cade Horton, 21, SP, CHC (A+)
43 IP, 12.56 K/9, 2.51 BB/9, 4.19 ERA

Horton hype season is in full swing. One of the fastest-rising pitching prospects per list-makers, Horton features a typical repertoire with mid-90s heat, multiple breaking balls, and a usable platoon changeup. The Cubs org is well-regarded when it comes to pitch design, a feature Horton could exploit as he moves up the ladder. He has enough feel for command to move quickly once the kid gloves are off. Presently, said gloves are on due to recovery from UCL replacement. He usually takes a week or more between starts of 15 to 20 batters. His last two outings have been among his shakiest of the season.

Three More

Coby Mayo, BAL (21): One of the nice things about Triple-A is access to minor league exit velocities. Mayo may not be hitting well through his first 36 plate appearances in Norfolk, but he has produced encouraging EVs – 90.6-mph average and 111.8-mph max. He’s currently batting .219/.278/.375 with a 36.1 percent strikeout rate.

Colt Keith, DET (21): Another recent promotee to Triple-A, Keith is hitting a modest .274/.347/.403 in 72 plate appearances. His EVs – 88.5-mph average and 108.9-mph max – are in line with figures from last season. I was hoping to see some obvious growth in this respect. His defensive limitations put a lot of pressure on the bat. We’ll see if the coming weeks bring harder contact.

Evan Carter, TEX (20): Despite success in Double-A, Carter has yet to receive a promotion. He’s batting .298/.415/.462 in 316 plate appearances. These stats match the scouting report. He has a superb eye and a solid feel for contact. The quality of that contact is…fine. It’s fine. Really. Given his current prospect pedigree, I’d really like to see better than “fine.”

Big Hype Prospects: Salas, Merrill, Yorke, Hence, Mayo

We missed a week while I was on the injured list (back spasms sustained while diving back to first base). There’s much for us to cover. Let’s start with some high-profile Padres. While the draft is tempting, let’s look in on those guys as they sign.

Five Big Hype Prospects

Ethan Salas, 17, C, SDP (A)
139 PA, 6 HR, 5 SB, .259/.381/.500

When we adjourned two weeks ago, Salas was batting .208/.340/.286 in 94 plate appearances. An 82 wRC+ isn’t anything to sniff at when we’re talking about a guy who’s 17-and-one-month old playing in full-season ball. Over the last two weeks, Salas hit .371/.467/.971. Including a HBP, he has as many free passes as strikeouts during the span. Of his 13 hits, he bopped five homers, four doubles, and a triple. That adds up to a 240 wRC+ for the hot streak and a 133 wRC+ on the season. If he keeps this up for long, he’ll find himself playing against High-A competition before the season ends. He’s “on pace” to debut as a teenager – a feat he can accomplish as long as he reaches the Majors before June 1, 2026.

Jackson Merrill, 20, SS, SDP (A+)
300 PA, 10 HR, 10 SB, .280/.318/.444

Salas’ future teammate had to grind through a rough April before turning a corner. The Midwest League is a difficult hitting environment. His first month of play consisted of a .188/.247/.338 performance. In the three months since then, he’s hit .317/.348/.487 while making steady improvements. Lately, he’s found a power stroke. Since June 14, he’s hit six of his 10 home runs. Merrill isn’t expected to be much of a power hitter. His carrying trait is an advanced feel for contact. He rarely meets a pitch with which he can’t connect. His discipline lags a bit, though it’s not as if he’s Javy Baez. An unsubstantiated theory of mine is that his early-season slump was the result of contacting too many pitches outside of the zone. The theory fits what data I have available, though I haven’t discussed it with anybody who would actually know.

Nick Yorke, 2B, 21, BOS (AA)
316 PA, 9 HR, 6 SB, .275/.361/.453

Folks weren’t sure what to make of Yorke’s forgettable 2022 campaign. The industry had a little chuckle when the Red Sox “reached” for Yorke in the first round of the 2020 draft. After a superb 2021 season, everyone adjusted expectations. Then 2022 happened. Some evaluators stuck with their updated outlook and blamed injuries. Others pointed to his subpar defense and wrote him off.

Yorke has rebounded this season – perhaps not enough to make up for his defensive shortcomings. His current 122 wRC+ depends upon a .353 BABIP. He also has 13.0 percent swinging strike and 25.0 percent strikeout rates. Historically, prospects with similar statistical performances have been prone to stalling out in the Quad-A bucket. For now, we should view Yorke’s rebound as a positive development. Perhaps more distance from his injury-riddled 2022 will lead to improvements in his quality or rate of contact.

Tink Hence, 20, SP, STL (AA)
(A+) 41.2 IP, 9.94 K/9, 2.59 BB/9, 2.81 ERA

Hence received a promotion to Double-A at the beginning of July. He also picked up a hold in the Futures Game. The pitching-needy Cardinals surely hope Hence can remain in the rotation. Alas, though he doesn’t walk many hitters, he’s not known for sharp command. His breaking ball is a weapon. It’s expected he should join the many pitchers who have mastered manipulating breaking ball spin for different effects. He doesn’t have a consistent changeup. Taken with the errant fastball command and history of brief outings, the relief risk is palpable. That said, Hence has yet to meet a challenge he hasn’t mastered. His Double-A debut was the first appearance of his career in which he faced more than 20 batters (22).

Coby Mayo, 21, 3B, BAL (AA)
347 PA, 17 HR, 4 SB, .307/.424/.603

With a 176 wRC+ on the season, Mayo is one of the top qualified hitters in the minors. He’ll play his next game in Triple-A, ending a nearly 500-plate appearance stint in Double-A. Mayo has traits grounded in the 2019 juiced ball era. He’s a pull-oriented slugger who generates plenty of loft. As a right-handed hitter, he’s not an ideal fit for Camden Yards. However, his power is such that he could overcome the home field limitations. It will be interesting to see if Mayo can continue to run elevated BABIPs into the Majors as this is a hitting profile typically associated with low BABIPs. Hypothetically, if a franchise-altering talent is made available at the trade deadline, Mayo would go a long way toward securing a deal. They’ll eventually have to trade somebody they like.

Three More

Johan Rojas, PHI (22): The Phillies are angling to get Kyle Schwarber into the DH slot. The plan would involve Cristian Pache in center and Brandon Marsh in left. If Pache doesn’t work out, Rojas has a similar reputation as a superlative defender who might hit enough to create a lot of value. In 354 Double-A plate appearances, Rojas is batting .306/.361/.484 with nine homers and 30 steals. He’s on the 40-man roster.

River Ryan, LAD (24): The latest pitcher to pop in the Dodgers system, Ryan features a promising four-pitch repertoire. In the month of June, he tossed two five-inning no-hitters. His command hasn’t been particularly sharp. Even across those two no-nos, Ryan issued four walks and hit three batters. It’s thought he’ll eventually develop better command. If not, he has a relief floor.

Ignacio Alvarez, ATL (20): A ripped shortstop who recently turned 20, Alvarez evokes Yandy Diaz right down to the comical biceps, low-angle contact, discipline, and rare whiffs. The comparison is hard to avoid. He might just be the next Brave to skip the line to the Majors. He generally keeps the ball on the ground with an all-fields approach. He’s expected to eventually move to third base, though he remains passable at shortstop for now.

Orioles, Fourth-Rounder Coby Mayo Agree To Above-Slot Bonus

The Orioles and fourth-rounder Coby Mayo have agreed to a deal, Jon Heyman of MLB Network reports. Mayo – the 103rd pick – will earn a bonus worth $1.75MM, which is well above the $565,600 recommended value of his selection. Notably, the Orioles lead the majors with a $13,894,300 bonus pool.

A high school third baseman from Coral Springs, Fla., Mayo had committed to the University of Florida before signing with the Orioles. Mayo didn’t wind up in the top 100 of Keith Law of The Athletic or MLB.com prior to the draft, but FanGraphs (No. 67) and Baseball America (No. 79) are more bullish on the 18-year-old. FanGraphs notes Mayo has “surprising bat control for size,” while BA credits him for his “raw power,” “solid zone recognition and a mature approach at the plate.” There are some questions as to whether the 6-foot-5, 215-pounder will stick as an infielder in pro ball, but the Orioles do view him as “strictly” a third baseman, Joe Trezza of MLB.com tweets.

With Mayo under wraps, the Orioles still have five other picks to sign, including second selection Heston Kjerstad and 30th choice Jordan Westburg.
