Shane Lowry loves the grind of a strong test and it's showing at Bay Hill. Bay Hill still had some bite, as Wyndham Clark, Scottie Scheffler and Xander Schauffele showed at various times. Lowry, playing alongside good friend Rory McIlroy, holed a 35-foot birdie putt on the 13th and closed with an 18-foot birdie to lead by two over Clark.
