Sophomore Jack Oberli led the Chaps at the plate with three hits, and Nick Fushi continued his fine play with the bat, but host and Region 4 Divison I leader South Suburban went on to win 9-5 on Friday.
 
The Chaps are at Kankakee College on Saturday.
 
Fushi's two-run double in the third gave the Chaps a 3-2 lead and they closed the inning with a 4-2 lead.
 
But South Suburban answered with a three-run third, and extended the lead to 8-4 in the fifth with a three-run inning.
 
Cliff Vickers and Mike Wagner also doubled for the Chaps, who were out-hit 13-9.
 
Fushi's effort capped a solid week, as he is hitting 8-for-15 (.533) in his last seven games.
 
Through 16 games, the Chaps are 5-11 overall, yet hold a 3-5 record in region play and 2-1 against fellow D3 teams.
 
South Suburban starter Conor Tomasic, a Purdue bounce-back, struck out nine in six innings.
