Breaking Down Luke Gabrysh And John Spikerman, The Return In Brooks Raley Trade

[N.B. Lindberg]

A day after shipping Freddy Peralta to Tampa Bay for three prospects, the Mets, as one of the few sellers employing impact talent, remained active in the trade market. Monday morning, they flipped left-handed reliever Brooks Raley to the Philadelphia Phillies for two 23-year-old High-A prospects– Luke Gabrysh and John Spikerman. 

Raley is in the midst of a strong season, but he was never going to land a haul commensurate with his 1.96 ERA. His strikeout rate of 23.5% and walk rate of 8.8% are only slightly better than the MLB averages for relievers (22.3% and 9.8%), and he has been relying on home run suppression (4.4% HR/FB) while being an extreme flyball pitcher (35.8% groundball rate) to produce a 3.10 FIP and 3.37 xERA. Rental relievers who rely on contact suppression are just not as hot a commodity in the age of the strikeout. Make no mistake, Raley is a good reliever, but only the cream of the crop land a haul for three months of work. 

The most important detail about Gabrysh, a right-handed pitcher, and Spikerman, an outfielder, is that they’re 23 and still in High-A. Any prospect who is old for their level needs to be dominant or possess outlier physical traits to be viewed as a future big leaguer, and neither Gabrysh nor Spikeman can really say that. 

Starting with Gabrysh, he is by far the more interesting of the two. His surface-level stats in High-A are not pretty: 5.14 ERA, 11.1% BB%, and 1.45 HR/9. However, he is sporting a 29% strikeout rate and is at least still starting. Stuff-wise, he has the goods to make the show, as his fastball, cutter, and sweeper all flash plus. The lack of a changeup or curveball makes his long-term prospects as a starter much more murky, and his scattershot control – he has hit 14 batters this season – already has him on the single-inning reliever path. 

However, pitchers who have multiple plus pitches should be given every chance to start. Despite averaging only 4 innings per start, Gabrysh, from a pitch count perspective, has been able to hold up to a starter’s workload for his level. 

If the Mets can help Gabrysh further refine his control and/or find a lefty-neutralizing off-speed pitch, he has a chance to be a starter, albeit an inefficient one. He isn’t Rule-5 eligible until December of 2027, which gives the Mets some runway to continue to develop him as a starter. If the control doesn’t come along by midway through next season, he’ll almost certainly be moved to the pen, where he could shoot through the minors if his stuff plays up in single-inning bursts with a more pared-down arsenal improving his strike throwing. 

The most likely outcome for Gabrysh is he’ll be an extremely volatile middle reliever. His stuff is good, but not so good he can just rear back and throw down the middle. The Mets should let him continue starting just for the reps, but I wouldn’t fault them for moving him to the pen and seeing just how nasty he can be in single-inning bursts. There’s a chance he takes to the pen and debuts in 2026, but 2027 is more likely. 

Spikerman is probably just organizational depth. He’s old for his level, and his future in center field is a bit murky. Despite excellent speed, he was moved off center field full time in 2025, and while he has played the vast majority of his innings in center this season, he probably needs to be plus in center to have any real future in the majors. 

There is good and bad news about Spikerman’s offensive profile. The good news is that he went from striking out nearly 30% of the time in 2025 to 22% in 2026. His contact metrics suggest he improved markedly in this department, which improves his chances of climbing the ladder from zero. 

The bad news is he has demonstrated absolutely no game power. He has hit three home runs in his minor league career; they all came last season in A-Ball, and his 90th percentile average exit velocity was only 100.4 MPH at A-ball in 2025. While his raw thump isn’t of the wet-noodle variety, he has struggled to lift or pull the ball, which he’d need to do at an exceptional rate to produce any power at the major league level. 

Despite his lack of power, he does own a 116 wRC+ at High-A this season, but it comes with a serious caveat. His profile is being carried almost exclusively by an excellent 19.5% walk rate, which is paradoxically not a good sign. 

Spikerman gets to his walks by being extremely passive. According to Prospect Savant, his swing rate of 35.98% is in the sixth percentile, and his in-zone swing rate of 59.29% is in the 16th percentile. The minors are littered with on-base machines who take advantage of wild minor league arms by simply not swinging. As he climbs the ladder, pitchers will more consistently pound the zone, and his lack of thump won’t make them pay. Functionally, his production looks like a house of cards built on a foundation of capitalizing on amateurish pitching. 

There’s a chance Spikerman can develop into a speed-centric fourth outfielder, but he’ll need to maintain his contact gains, develop a bit more power, and improve defensively enough to be viable in the majors. That’s a lot of “ifs” for a 23-year-old in High-A to overcome. However, he has shown real improvement at the plate season-to-season, which gives him a slim chance. The ability to make adjustments is the defining characteristic of baseball, and Spikerman has at least shown some aptitude to do so.

There a chance Gabrysh becomes the next Tarik Skubal but the chance involves murdering him and consuming his heart.
