THE WOODLANDS, Texas — Lilia Vu’s title defense of the Chevron Championship was over before it began. The world No. 2 had a nagging back injury flare up during warm-ups at the Club at Carlton Woods and withdrew from the event before her 1:10 p.m. CDT tee time, according to an LPGA official. Vu is expected to release a statement later in the afternoon.
