Brooks Koepka's puzzling wrist injury results in second-straight last-place finish

KAPALUA, Hawaii — Brooks Koepka finished in last place for a second straight start on Sunday, pulling up the rear at the winners-only Sentry Tournament of Champions.

What’s wrong with the reigning U.S. Open champion?

For starters, he’s still plagued by a left wrist injury, something that also bothered him at last month’s Hero World Challenge, where he shot three-over 291 in the 18-man field. Prior to that, he finished first and second in his previous two starts.

This week at the Plantation Course, Koepka posted a pair of 78s and didn’t break par in any of his four rounds, shooting 75 on Sunday to finish at 13-over 305.

“I haven’t gotten past it,” said Koepka, who said he isn’t sure how he hurt the wrist or what’s exactly wrong with it. “It’s not fun. Nobody can come up with an answer.”

He added that it hurts “everywhere” in his swing.

“Wednesday, it hurt like hell,” he said. “It’s like someone’s jabbing a knife in my wrist or hand.”

For now, Koepka will head home, where he’ll take the next three weeks off before returning at Phoenix and Pebble Beach the week after that.
