Experienced caddy Billy Foster has backed Jordan Spieth to win this weekend's US PGA Championship at Whistling Straits.
Spieth, 22, had hoped to be in contention to wrap up the Grand Slam of Majors over the next four days, but having won The Masters and US Open earlier in the year, he could only finish fourth at last month's British Open in Scotland.
Nevertheless, Foster, who will be on Lee Westwood's bag in Wisconsin, has tipped the young American to bounce back from his disappointment at St Andrews to lift a third Major title of 2015.
"I don't think you can look past Jordan Spieth the way he's going. He is a very mature, cool, professional, diligent man who works really hard and does his homework," Foster told 888sport.com.
"He's a good scholar who does all the right things. He is a formidable professional with a fantastic attitude way beyond his years and a short game to die for. He's going to be around a long, long time."
Spieth has featured at the US PGA Championship twice before, but missed the cut on both occasions.
