(Reuters) - Former champion Matt Kuchar continued his love affair with the Memorial tournament on Friday as he took advantage of calm conditions with a late birdie flurry to surge into a two-way tie for the early lead in the second round. Kuchar birdied four of his last six holes to shoot a sparkling six-under-par 66 at Muirfield Village, finishing level with fellow American Brendan Steele (67) at 12-under 132. Argentina's Emiliano Grillo (66) and long-hitting American Gary Woodland (65) were at 11-under while Australian world number one Jason Day followed his opening 66 with an erratic 71 to drop five strokes off the pace.
