Big Hype Prospects: Grissom, Walker, Holliday, Lee, Painter

This week on Big Hype Prospects, we check in with a couple recently-promoted Major Leaguers, peek at a couple more on the cusp, and introduce ourselves to some hot-hitting 2022 draftees.

Five Big Hype Prospects

Vaughn Grissom, 21, 2B/SS, ATL (MLB)
35 PA, 2 HR, 2 SB, .406/.457/.656

Grissom was just playing his way into consensus Top 100 status when the Braves tabbed him for a Major League promotion instead. He had just 98 plate appearances in Double-A after spending much of the season in High-A (344 PA, 11 HR, 20 SB, .312/.404/.487). His numbers have actually improved slightly at each stop. As many have noted (unpleasant noise warning), he’s the second player the Braves have skipped straight past Triple-A. Of course, 35 plate appearances is hardly the basis for Major League success – the true challenge is proving the ability to counter-adjust once the league figures him out. We might not get to that point since Ozzie Albies is approaching a rehab assignment. Grissom will probably hold down the fort until then.

His arrival also has long-term implications. He mostly played shortstop in the minors. So too did Albies back in the day. The club could be using this opportunity to further their postseason bid by using a more dynamic player than Ehire Adrianza while at the same time assessing if a shortstop signing is an urgent need this winter. If they like what they see from Grissom, the Braves might opt to target a lesser free agent like Jose Iglesias or even skip the market altogether.

Jordan Walker, 20, 3B, STL (AA)
430 PA, 15 HR, 17 SB, .310/.393/.522

On Thursday, Walker had his third double-dinger game since July 29. He appears to have accomplished all that he can in Double-A by both improving upon his walk and strikeout rates while continuing to punish the baseball. One of the big impending storylines of free agency is Nolan Arenado’s player option decision. Will he stay or hit the open market? Judging by the ascendancy of Walker, St. Louis might be alright with letting Arenado walk. After all, they can always use Nolan Gorman at third base if Walker isn’t ready in early 2023.

There are still some issues with Walker’s game hidden underneath the beautiful surface level stats. For one, he has a 16.1 percent swinging strike rate. That’s roughly on par with Adolis Garcia, Ryan Mountcastle, Jorge Mateo, and Patrick Wisdom – not exactly the most contact-oriented collection of batters. Moreover, Walker has these whiff issues while running a 45…
