ST. LOUIS – John Klein scored his fifth and sixth goals of the season in the first 16 minutes to give Saint Louis the upper hand, and the 10th-seeded Billikens went on to register a 5-1 NCAA Championship second-round victory over LIU Sunday afternoon before a Robert R. Hermann Stadium record crowd of 6,815.
 
The win propels SLU (15-0-4), the only undefeated NCAA Division I men's soccer team this season, to the round of 16. The Billikens will face 7th-seeded Duke -- a 2-1 second-round winner over UCLA -- Saturday, Nov. 27, at 6 p.m. Central in Durham, North Carolina.
 
LIU, champion of the Northeast Conference, finished with a 12-5-4 record. The Sharks advanced to Sunday's second round with a 1-0 win at Maryland.
 
Klein gave Saint Louis the lead in the fourth minute, taking a long pass from Chandler Vaughn and outmaneuvering an LIU defender and the Sharks' goalkeeper from close range. The assist was Vaughn's second of the season.
 
Klein doubled the lead just over 12 minutes later. A.J. Palazzolo began the play by eluding two opponents and tapping the ball to Isaiah Parker. Parker lofted a pass to Klein, who beat the keeper with a flying header. Parker tallied his seventh assist of the year, while Palazzolo picked up his first.
 
Christian Buendia made it 3-0 in the 21st minute with his second goal of the season. Simon Becher flashed into the box, settled the ball and dropped it off to Buendia, who tucked a shot just inside the left post. Becher's assist was his ninth of the season.
 
Robert Winkler scored LIU's only goal, unassisted, in the 23rd minute.
 
The Bills quickly regained their three-goal cushion in the second half, scoring in the 47th minute. Becher received a booming ball from goalkeeper Patrick Schulte, outraced an LIU defender and rolled his team-leading 13th goal past a drawn-out goalkeeper. Schulte collected his first assist of the year.
 
Palazzolo finished the scoring in the 70th minute, notching his third marker of the year. A Saint Louis corner kick was headed out by LIU directly to Palazzolo, who buried a shot into the upper left from 20 yards out.
 
The Billikens outshot the Sharks 11-7 overall and 8-2 in shots on goal. SLU also earned a 5-0 advantage in corner kicks.
