After marching through the first four rounds of the NCAA Men's Singles Tennis Tournament without losing a set, Pelva was defeated 3-6, 5-7 in the round of four.
Pelva had a chance to tie the match in the second set, but dropped five consecutive games to Becker after running out to a quick 5-2 lead.
"In the first set, Becker served well and Gabor was a little shaky," Tigers' coach Eric Shore said. "He was up 5-2 in the second set and just couldn't close it out. He missed some balls he hasn't missed all week.
"But, you can't take away from all that he has accomplished. He has been our No. 1 guy all year and has done great things for us. He made it to the top four and that is something that no one else at Auburn has been able to do and we have had some outstanding players pass through here. It puts him in a position to be a top 10 player heading into next year. He just really had a great season."
