AUGUSTA, Ga. — The second round of the Masters opened with tumult and sloppy play.

The first-round leader Jordan Spieth started Friday with a double bogey on his first hole. Then he bogeyed the next hole.

A little while later, Phil Mickelson, who began Friday just four strokes off the lead, found himself in the woods, where he tried a recovery shot that ricocheted off a tree trunk and disappeared in a bush. There may have been symbolism in that result since Mickelson soon disappeared from the leader board.

Not long after Mickelson’s misadventure, Tiger Woods clubbed his ball from the pine straw alongside a fairway and sent it rocketing into the darkest reaches of a grove behind a green. Woods ended up shooting a three-over-par 75 and barely qualified to play the rest of the tournament. Woods is now four over for the tournament, and Mickelson, one shot behind him, made the cut by only a stroke.

But after all the early hardship and ugly play, a host of other golfers later in the day played with a poised efficiency that sent them surging into contention. In the end, the Masters’ halfway point brought a leader board stacked with past major champions, including Spieth, who rebounded from his poor start.
