BATON ROUGE, LA., JUNE 3 -- Rob Muzzio, two-time NCAA champion from George Mason University, was in second place tonight after five events of the decathlon in the NCAA track and field championships.

Sheldon Blockburger of Louisiana State led the field with 4,266 points, a first-day record. Muzzio, the winner in 1984 and 1985, was next with 4,173 and Jim Connolly of UCLA was third with 4,158.

Muzzio finished fifth in the 100 meters in 10.89 seconds, third in the long jump at 23 feet 1, won the shot put at 52-11, was seventh in the high jump at 6-4 3/4 and sixth in the 400 meters in 49.05.

Texas A&M's Floyd Heard, the collegiate record holder in the men's 200-meter dash, broke the Bernie Moore Stadium record in a heat, running 20.27 seconds. The previous record was 20.54, set by Tony Dees of Mississippi in 1984.

Heard set the NCAA record of 19.95 in the Southwest Conference championships May 17.

Heard also helped Texas A&M's 400-meter relay team set another stadium record, the Aggies winning their heat in 38.89, the second-fastest time in the world this year.

The performance by Lawrence Felton, Heard, Greg Lewis and Stanley Kerr was well under the previous stadium record of 39.10, established by Texas Christian in 1985.

Another stadium mark fell in the women's 400-meter hurdles as Mimi King of Texas led the advance into Friday's final with a time of 56.67.

Favored Kevin Young of UCLA led the qualifiers into Friday's final of the men's 400-meter hurdles, winning his heat in 49.14.

Three others -- Pam Klassen of Rice (9:09.44), Annette Hand of Oregon (9:09.64) and Liz Natale of Texas (9:09.84) -- also were under the previous stadium mark of 9:10.79, set last year by Stephanie Herbst of Wisconsin.
