MLB.com - Mayo (6/2)
Kumar Rocker, RHP, Vanderbilt

A rough SEC Tournament outing for Rocker didn't help his standing, but the size and arm strength should keep him from falling too far.

The Athletic - Law (5/27)
Jack Leiter, RHP, Vanderbilt

They'd love Lawlar, and I would say there's a non-zero chance he gets here; if Texas takes Rocker or Leiter and Boston takes the other, that probably pushes Lawlar here, with Baltimore likely going under slot.

MLB.com - Callis (5/26)
Kumar Rocker, RHP, Vanderbilt

Rocker was MLB Pipeline's preseason No. 1-rated prospect and has performed well for much of the season, though there's also some thought that the D-backs may want a hitter here. Of the players who could realistically get to No. 6, Davis might be the preferred choice, and Arizona also has scouted House and Watson extensively.

ESPN - McDaniel (5/11)
Sal Frelick, CF, Boston College

It's unclear exactly what the Diamondbacks do here, but Frelick fits their preferences perfectly. Davis is a nice fit as well, and House doesn't really fit them at all. Looking at Corbin Carroll, Alek Thomas and Matt McLain, you can see the trend in up-the-middle contact-first shorter-armed types, and Frelick is exactly that. He's a 70 runner with at least average raw power, above-average contact skills and some background playing the infield if they want to move him to second base at some point. Due to his size, I don't think Frelick goes much higher than this, but I also don't think he gets out of the top 10.
