Tiger Woods is taking the high road in his nasty split with caddie Steve Williams.

Woods says Wednesday he was happy to see Adam Scott win a World Golf Championship last week. He said he even sent a text of congratulations to his ex-caddie, who now works for the Australian.

He says he was surprised that Williams took a shot at him on national TV when the tournament was over, and that they have exchanged texts since then. Woods says that's between him and his former caddie, and he doesn't want to speculate why Williams was so motivated to win.

As for his own hopes in the PGA Championship, Woods says it's always about winning. He also revealed, though, that his improved health is enough to make this year successful.
