Tiger senior Shane Jewett scored a hat trick  and Waynesville upset Missouri's Class Two second ranked Rolla Bulldogs 3-2 in overtime Thursday night at Anderson Field.  A happy group of Tigers mobbed Jewett when his third goal, a long, right-footed shot  from the left side, struck high in the back of the net five minutes and 43 seconds into the first OT.  Jewett had already brought the Tigers back twice in the game scoring on breakaways early and late in the second half to offset a pair of Aaron Froelich goals for Rolla.  A throw in from Brandon Ruess helped to set up the winner.  Also playing a key roll in the win was Tiger goalkeeper Jon Moore.  He had ten saves and smothered several other Bulldog attacks.  Rolla enterd the game with a 15-1 record and trailing only defending state champion St. Dominic in the polls.  The big victory moved the Tigers' Ozark Conference record to five and two and assured them of a winning record in the conference.
