Zak Irvin said before the July recruiting period began that he wanted to become more than a shooter, to work on his ability to get to the basket. He wanted to round out as much of his game as possible before his senior season, including working with trainer Shon Bolden and some NBA players to pick up pointers.

That work paid off for the Fishers, Ind.. native during July and now in August as well. Irvin became one of the biggest risers in the new 2013 ESPN 100 rankings, leaping from No. 60 in June all the way up to No. 21 in August.

Irvin, Derrick Walton Jr. (Harper Woods, Mich./Chandler Park Academy), Mark Donnal (Whitehouse, Ohio/Anthony Wayne) and Austin Hatch (Fort Wayne, Ind./Canterbury) comprise the No. 2 class in the country in ESPN.com’s newest team rankings for the Class of 2013, trailing only Florida.

Irvin’s big individual move coincided with a summer where he impressed at every tournament he played in throughout July, vaulting him into being the No. 5 small forward in his class entering his senior season at Hamilton Southeastern.

If Irvin’s new ranking holds, he would be Michigan’s second highest-rated commit since ESPN.com first started doing player rankings in 2007. Last season, Glenn Robinson III finished his ascent as the No. 18 player in the country. At his peak last season, forward Mitch McGary was the No. 2 player in the country, but he was No. 27 in the final rankings.

Irvin wasn’t the only Michigan commit to make a move.

Point guard Derrick Walton (Harper Woods, Mich./Chandler Park Academy) also made a jump from No. 40 in the May rankings up to No. 32. He pushed his way up the point guard rankings as well, moving from No. 9 point to No. 5.

Donnal, the third commit in the Wolverines’ 2013 class in the ESPN 100, dropped from No. 64 to No. 97, but he still gives Michigan three players in the ESPN 100. He is rated the No. 24 power forward in the country.

While Michigan has no 2014 commits, three of the players it has offered are in the ESPN Super 60, led by shooting guard Devin Booker (Moss Point, Miss./Moss Point), who checks in at No. 21, moving up slightly from his No. 23 ranking in May. Forward Keita Bates-Diop (Bloomington, Ill./University) moved up from No. 43 to No. 30 and swingman Trevon Bluiett (Indianapolis/Park Tudor) entered the rankings at No. 50.

More impressively, Booker is considered the No. 2 shooting guard in his class, behind only Rashad Vaughn. Bates-Diop is ranked as the No. 5 power forward and Bluiett as the No. 17 small forward.
