McIlroy and Scheffler struggle at Memorial Tournament as JT Poston leads

JT Poston made light work of tricky, windy conditions to take a one-shot lead at the Memorial Tournament as the world's top two Rory McIlroy and Scottie Scheffler struggled.

McIlroy had no form on the fast putting surfaces as he signed off his second round with a 74, which included three bogeys and a double-bogey having taken five shots to get down from 112 yards out at the par-four 13th.
