It's a four-way tie for the top at the Masters, with Thomas Pieters and Rickie Fowler joining Charley Hoffman and Sergio Garcia late in the second round.

Pieters is a 25-year-old Belgian playing his first Masters. He had five birdies in his first 10 holes Thursday to move in front at 5 under. However, two double-bogeys down the stretch sent him back to even par.

But Pieters was at it again in the second round, with an eagle on the par-5 13th and a birdie on the 14th to catch Hoffman and Garcia, who were both in the clubhouse at 4-under par.

Fowler joined the quartet with his birdie on the 13th hole.

The group is two shots clear of the next four ties at 2-under, which includes three-time Masters champion Phil Mickelson, 1992 green jacket winner Fred Couples and Olympic gold medalist Justin Rose.
