TRACK & FIELD—At the Los Angeles Times Indoor Games KJELL ISAKSSON of Sweden set a world indoor record in the pole vault with a mark of 17'7¾", bettering the standard of 17'7". MEL PENDER, who later in the week tied his indoor mark of 6.8 in the 70-yard dash, edged Jean-Louis Ravelomanantsoa of Westmont (Calif.) College in the 60-yard dash, a 10th of a second off the world record. Both runners were timed in 6.0 seconds. HENRYK SZORDYKOWSKI of Poland and JOHN MASON tied in the mile run as they were timed in 3:58.9. RANDY MATSON bested Al Feuerbach to make it five out of six in their continuing duel with a toss of 67'11¾" in the shotput.

The 9:31.5 time cannot be recognized as an indoor record because it occurred on an oversized, five-laps-to-the-mile banked track. The UNIVERSITY OF WISCONSIN'S two-mile relay team was timed in 7:19.8 to establish a new world indoor mark, but also on the oversized track. CHRISTA MERTEN of West Germany set a world indoor record for the women's 1,500 meters in 4:17.9, and her teammate HAROLD NORPOTH turned in a world indoor record for the men's 1,500 with a 3:37.8.
