Adam Walton and Michael Zheng meet in the quarterfinal at Bloomfield Hills on Friday. Adam Walton has won 7 of the last 10. Michael Zheng comes in at 4 wins from the last ten.
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
The underlying stats are tight across the board — this is a matchup decided by a handful of points. Little separates them; Walton gets the nod on the finest of margins.
