Martin, who qualified with just one throw in the hammer, did it on his first one in the shot put, too, and added a second throw that went 63 feet, 3/4 inch, which was the third best in the prelims.
"I wasn't expecting to hit the auto mark on my first throw," Martin said. "My warm-ups were going well and the first throw was far enough that I was comfortable that I could make it in to the finals, and the second throw was just so I could get out of here since I have the hammer tomorrow."
Kerron Stewart, the favorite in the women's 200 meters, won both of her heats to advance to Saturday's final. She won her first race in 22.77 and her second round in 22.52, the fastest time of all the qualifiers. She has not lost a race all season.
"I'm definitely pleased with the way I ran today," the senior said. "It's all about getting to the finals and I did that. I'm very confident, I've been training hard and I'm healthy, so I'm ready to go."
Kerron Stewart is a six-time All-American counting indoor and outdoor season competitions.
Reuben McCoy, who has a solid chance to score in the men's 400 meter hurdles, advanced to the semi-finals of that event. He won his prelim event with a time of 50.90 and will compete in the second round on Friday.
The only disappointment on Thursday was a scratch by Danielle Gilchrist, who was injured and could not compete in the women's 400 hurdles.
"I'm really pleased with the effort since the time we got here," said Auburn's head coach Ralph Spry. "We came in really focused and we're feeding off the success we had the first day. Today was just another example of that. Right now we're competing extremely well, and if we can keep that momentum going, we're going to give ourselves a good shot of scoring a lot of points the last couple of days."
On Friday, Martin and Jacob Dunkleberger will compete in the hammer finals, Donald Thomas will be in the high jump finals, Ty Akins will be in the finals of the 110 hurdles and Tracy Ann Rowe will compete in the 100-meter women's final. Michelle Vaughn will compete in the triple jumper prelims.
