BASKETBALL—SAN FRANCISCO moved two games ahead in the West as it won three of five while second-place ST. LOUIS split four. Will Chamberlain (see page 24) scored 52 points back to back and climaxed a big week (averaged 43 points a game) by stuffing in a short shot by Guy Rodgers with seven seconds left to beat the Lakers 109-108. Luckless LOS ANGELES dropped four out of five (three of the losses were by one point, the other by two) to fall six games out of first and within four of fourth-place BALTIMORE, which snapped out of a three-game losing streak with two wins in a row. DETROIT, on the other hand, broke its seven-game winless streak with a victory over L.A. and immediately lost three more in a row. In the Eastern Division, second-place Cincinnati won three out of four to climb within a game of BOSTON, which split four, and suddenly, with only three and a half weeks left in the season, there was a race for first place. A month ago the Celtics held a seemingly safe five-game lead, but the Royals gradually cut that down by roaring to 14 victories in 15 games (including 12 straight) while Boston was winning 12 of 19. PHILADELPHIA lost its third game in a row (to the Celtics 103-93) and then won three straight (including a 144-119 romp over the Celtics in which Hal Greer scored 50 points). NEW YORK followed up its nine-game losing streak with a season high of three victories in a row as rookie Art Heyman averaged 25 points a game. The fun ended when the Knicks lost their next game to the 76ers 114-105.
BOBSLEDDING—At Lake Placid, N.Y. Olympic silver medalist SERGIO ZARDINI of Italy won the international Diamond Trophy, the North American four-man title, and placed second in the two-man event, which was won by Larry McKillip of Saranac Lake.
BOXING—Sixth-ranked heavyweight EDDIE MACHEN of Berkeley, Calif. quickly left-hooked 6-foot 6-inch Duke Sabedong down to manageable size and knocked him out with a right uppercut in the first round, for his fifth KO in as many fights since he started his comeback five months ago.
Johnny Persol of Brooklyn. 23, climbed back into the ring after a jolting right sent him sprawling in the sixth round and turned a ferocious attack on top-ranked light heavyweight Eddie Cotton to earn a split decision in 10 rounds at Madison Square Garden.
GOLF—Finally admitting his age (51), SAM SNEAD entered his first PGA Seniors' Teacher Trophy tournament, in Palm Beach Gardens, Fla. (see page 52) and shot a nine-under-par 279 to win the $2,500 first prize.
HOCKEY—MONTREAL briefly took over first place by winning two in a row (including a 3-1 victory over the Black Hawks) while CHICAGO was splitting two games. But the two teams ended up tied for the lead for the fifth straight week when the Canadiens lost one and the Black Hawks shut out the Bruins 2-0. Third-place TORONTO held its four-point lead over the Red Wings by tying them 1-1 and winning two in a row from the Rangers, as DETROIT, the best team in the league the past three weeks (seven wins, one tie in 10 games), followed suit with two straight 3-2 victories over the Bruins and the Canadiens. Fifth place NEW YORK sank 12 points behind the Red Wings, by losing three more in a row (eight of their last nine), and BOSTON dropped clear out of sight by losing its third, fourth and fifth consecutive games.
HORSE RACING—ROMAN BROTHER ($3), under Manuel Ycaza, overtook Mr. Brick in the closing strides to win by a head the $30,550 Everglades Stakes for 3-year-olds at Hialeah.
The 1963 turf champion, MONGO ($7.60), found the mud at Hialeah no handicap and took an early lead under Wayne Chambers to defeat Sunrise Flight by a head in the $130,800 Widener Handicap.
Another good turf runner successfully switched surfaces when MR. CONSISTENCY ($13.60), urged by Kenny Church, took the $147,100 Santa Anita Handicap by� of a length.
MOTOR SPORTS—Plymouths swept the first three places in the Daytona 500 (see pane 26) as RICHARD PETTY of Randleman, N.C. set a track record by averaging 154.334 mph and lapped the field twice in spite of six pit stops and three caution lights.
