Reinforcing his earlier endorsement, Andy Lack specified his exact buy range on Xander Schauffele: he will only fire if books hang 14-to-1, 15-to-1, or 16-to-1. Anything in the 10-to-11-to-1 neighborhood is a hard pass. Lack’s conviction stems from Schauffele’s rock-solid Memorial resume—seven top-25s in eight starts—and the fact that he just gained 5.6 strokes off the tee at Quail Hollow, showing the driver is peaking heading into another long, thick-rough, Jack Nicklaus test. Schauffele ranks second in Lack’s model on "big five" venues like Riviera, Torrey Pines, Bay Hill, and Muirfield Village, all of which demand complete tee-to-green games. The actionable edge is waiting for slow-moving books that open Scheffler at +300 and push Xander deeper than 14-1; that is where Lack is ready to pounce with outrights and each-way bets.
