Derrick Walton continues to be perceived as the crown jewel of the Michigan basketball team's 2013 recruiting class.

But current pledge classmate Zak Irvin appears to finally be hot on his heels.

National recruiting site Scout.com updated its 2013 rankings Tuesday, and Walton -- a four-star point guard from Chandler Park Academy -- came in at No. 43 overall, the eighth-best lead guard in the class.

Irvin, meanwhile, made his debut in Scout's rankings -- coming in at No. 62.

Irvin, a 6-foot-5, four-star small forward from Hamilton (Ind.) Southeastern, has been routinely ranked among the top 75 by both Rivals.com and ESPN.com for some time now. Scout.com had been the lone member of the top three recruiting services not to rate him.

No longer, though.

Irvin may also make a leap forward in ESPN's next batch of rankings, as he received high praise as perhaps the "best overall player" at the recent Adidas Invitational in Indianapolis.

"He has terrific size for a small forward and consistently knocked down 3-pointers on the break or coming off screening action in the half-court set," ESPN wrote of the high-scoring swingman. "He can also get all the way to rim with his drive or find an open teammate. Overall, Michigan landed itself a player who competes hard and can fill up the stat sheet."

As for Walton, his ranking rise might not be done either. ESPN national senior basketball recruiting analyst Dave Telep noted on Twitter recently that Walton's name should be tossed into the discussion for the 2013 McDonald's All-American game.

Michigan's other top 100 player for 2013, 6-foot-9 power forward Mark Donnal, remained steady at No. 80 in Scout.com's rankings.

Donnal, a four-star performer from Anthony Wayne (Ohio) High School, is also seen as a top 100 player by both ESPN.com and Rivals.com.
