2026 Phillies Draft Preview Jared Grindlinger, LHP/OF

I always like to start previews with my favorite prospect. That’s often someone the Phillies have no chance at, but not this year. A reclassicification of draft eligibility made this year’s mystery box my favorite, most intriguing option. Grindlinger is a left handed Outfielder and Pitcher and is a potential 1st/2nd rounder in both roles. He also has a perfect name for Philly, who would certainly love someone to grind it out in either role for a decade or more. The catch is Grindlinger will be one of the youngest players to be drafted in league history as he’s currently 17 years old as of April 16th. He’s already 6’3” and 185lbs and at barely 17 there’s a chance a little more growth may be coming. He’s committed to University of Tennessee for College. He reclassified to the 2026 draft in mid-February, so I don’t get the sense he plans on sticking to that commitment barring a drop in draft stock

The draft stock is tough to gauge, as Baseball America mocked him to the Phillies in their first mock draft and didn’t have him at all in their second and in their third mock, they have him going 20th. He was the #3 prep prospect in the 2027 class, so it’s reasonable he’d still be a first rounder here. Teams also seem to be flip-flopping a bit on what role he’s better in. At first it was solidly pitching, but consensus seems to have moved to hitting. I’ll write up both here.

I’ll start with Pitching, since that seems to have taken a bit of a backseat in his profile, I’ll give more of a Cliff Notes version. This is still a very viable path for him in the pros though. As a Pitcher, he already has an Above-Average Fastball that sits mid-90’s and he can get up to 96 to go along with a low 80’s Slider and Changeup. Both could end up Above-Average or better. Grindlinger throws from a 3/4 slot and the 4-seamer shows good carry and arm side tail. He has a good track record of throwing all 3 for strikes, though like all Prep Pitchers all 3 pitches need some work on consistency and command. The ceiling is probably #2 Starter.

As a hitter the hype train has really gotten rolling for Grindlinger. To be honest, I get it for the potential, but there are also some warning signs that I think will limit how high he can go in the draft. Everything is projection at this point. While that’s true for all prep players, it’s especially so here. He’s well beyond his years at the plate showing patience and elite contact rates in and out of the zone. He simply doesn’t swing at things he can’t put in play. This sounds great, but he’s also facing fellow prep arms with a mixed bag of secondaries. Part of the concern stems from his bat speed being below average, the other part comes from him having a flat bat path and a likely trade off trading contact for power in pro ball. He already manages average power, but he’s likely destined for Right Field as a pro where his 55 grade speed and plus arm can best play up, and teams want to get above-average or better power out of that position ideally. There’s a little to that hitting profile, though here you’d also be projecting additional muscle adding to his bat speed some and to his power overall.
