He'll be hard to miss today when he tees off in the last group with co-leader Tom Lehman at the 71st Senior PGA Championship.
Blake, of St. George, Utah, shot 2-under-par 70 on Saturday at Colorado Golf Club to take a share of the 54-hole lead at the senior circuit's oldest and most prestigious event.
Lehman fired 71 through swirling winds that add to the adversity facing golfers at the 3-year-old course co-designed by Ben Crenshaw, a 7,450-foot monster.
Fred Couples, who led going into the weekend, faltered with 75 but is still just two shots off the pace, along with Mark O'Meara (67) and Mike Goodes (70).
Seven others are within four strokes of the leaders.
"There are six or eight or 10 guys that if they play good tomorrow can win it," O'Meara said.
That group features Lehman, who played steady golf in the final group while playing partners Couples and Tom Kite (79) stumbled.
Augusta native Larry Mize had 70 and is tied for 13th place at 215, or five shots off the lead.
Blake, the 1980 NCAA champion, has won twice a pro: in 1991 at the Shearson Lehman Brothers Open and the Argentine Open.
Blake said earlier in the week that he thought he had a good shot here because his game is in top shape and so is his back, which bothered him for past nine years on the PGA Tour after he rejected his doctor's advice and returned too soon from an appendectomy.
EUROPEAN TOUR: In Madrid, Rhys Davies, of Wales, and Luke Donald, of England, share a two-shot lead going into the final round of the Madrid Masters.
Davies shot 5-under-par 67 in the third round, while Donald had 68. The two are 16-under 200.
Italy's Francesco Molinari had five birdies in the first seven holes for 65 that left him two shots back, while Alvaro Quiros, of Spain, was another stroke back after 64. Quiros is going for a second victory on home soil this season after winning the Spanish Open.
Graeme Storm, of England, (67) is four back.
Former Augusta State star Oliver Wilson shot 70 and is at 211, or 11 shots off the lead.
Donald's last victory on the European Tour was the 2004 European Masters, while newcomer Davies won in Morocco earlier this year.
LPGA TOUR: In Rio de Janeiro, Brazil, Sweden's Maria Hjorth shot 5-under-par 68 to take the lead in the HSBC LPGA Brasil Cup.
Hjorth has a one-shot lead over Meaghan Francella and Marajo Uribe in the 36-hole tournament, which concludes today.
There are 27 players in the event, which is being played at Itanhanga Golf Club.
