Daniel Gliner in the 18s and Brandon Mitchell in the 16s produced major upsets on Monday in third round singles action at Stowe Stadium.

Mitchell, a 15-year-old from Laguna Niguel, CA, overwhelmed No. 6 seed Matt Spindler of Sacramento, CA 6-1, 6-1 on a cloudy and humid Monday morning, while Gliner\'s 6-3, 6-4 upset of No. 5 seed Johnny Hamui came in the late afternoon sunshine on court three with plenty of crowd support, including some of his Northern California buddies.

"Not a lot of people thought I was going to win," said Gliner, a 17-year-old from San Francisco. "But all my friends were telling me I had a chance. I had some belief at the beginning, but not much, and as the match progressed my belief increased."

Hamui, of Wesley Chapel FL, took a 4-1 lead in the second set, but there was no comeback for him, with Gliner making disheartening gets and hitting outright winners.

"There was a game at 4-2 (in the second) where I got like three lobs back in a row," said Gliner. "He missed the overhead, and I think that was the turning point."

There was no turning point in a match as lopsided as Mitchell\'s victory over Spindler, but the left-hander admitted that he was at the top of his game.

"My forehand was working really well, and also my serve," said Mitchell, who is playing for the first time in Kalamazoo. "If you have a good serve, it\'s a big advantage. He wasn\'t playing the best he could probably," Mitchell added, acknowledging that he had displayed his best tennis.

Tennys Sandgren, the 16s\' top seed, certainly didn\'t play at his highest level, but he found his way out of a tight spot, down a set and a break to unseeded Thomas Pham of San Diego CA before posting a 4-6, 6-2, 6-3 victory.

"He was playing really well," said Sandgren, the 2007 16s Clay Court champion. "I wasn\'t, but he sure didn\'t make it any easier."

Both players cramped, but it was Pham who called a trainer, down 3-1 in the third.

"I was cramping early in the third, but I didn\'t want to sit down," Sandgren said when asked why he didn\'t seek any medical attention. "I thought standing, moving, drinking water would be the best way to get through it."

Sandgren felt first-hand the Kalamazoo fans\' famous support for the underdog during a lunchtime match on court one.

"It was a little annoying," Sandgren said good-naturedly. "You try to block it out, but it\'s hard." The Gallatin TN resident then spoke of what he was looking forward to when coming to Kalamazoo as the No. 1 seed.

"Playing on court one, having the crowd behind me," he said, then added after a beat, "You can scratch that one."

Sandgren wasn\'t so fortunate in doubles, as he and Walker Kehrer, the No. 2 seeds, lost to the unseeded team of Ryan Kim and Spindler.

The 16s singles seeds falling on Monday included No. 15 Gabriel Flores, No. 19 John Huang, No. 25 Ryan Cheung, No. 28 Sidarth Balaji, No. 31 Brian Fang and No. 32 Michael Vutam.

Gregory Andrews of Richland, MI, located about 10 miles east of Kalamazoo, reached the final 32 with a 3-6, 6-3, 6-3 win over Dante Terenzio of Stamford CT.

The 18s saw fewer surprises, with Hamui the only Top 16 seed to lose on Monday. But in the 17-32 category, No. 20 Alex Domijan, No. 22 Joey Burkhardt, No. 25 Jeff Dadamo and No. 27 Nick Meister failed to make the fourth round.

In 18s doubles, the only upset saw No. 11 seeds Will Guzick and Steve Schechtman lose to Joshua Graves and Luke Marchese.  Only four seeded teams did not reach the final 16.
