The unseeded junior won in straight sets as he did in his first two NCAA matches, taking out the Pac 10 Conference Player of the Year 6-3, 7-6 to set up a rematch with Chad Harris of Vanderbilt on Saturday. Pelva won a regular season meeting earlier this year.
"Gabor had to deal with a lot of different conditions today," Auburn coach Eric Shore said. "It was hot, humid and no wind, but he handled it well and pulled out the tie-breaker in the second set. Again, he is just going at it one match at a time and this one will be with a very familiar opponent tomorrow."
Pelva has a 2-0 record vs. Harris, including a 4-6, 6-1, 6-4 victory this season. They will play at 1 p.m. on Saturday with the winner advancing to the semi-finals to face either Benjamin Becker of Baylor or Hamid Mirzadeh of Florida.
On Wednesday to open play in the 64-player draw, Pelva defeated New Mexico's Divan Coetzee 6-4, 6-2. In round two on Thursday, Pelva took a 6-2, 6-3 victory over Doug Stewart of Virginia.
