The Wisconsin TimberRattlers had an exciting finish to their homestand, completing a sweep of the Beloit Snappers with an 8-7 victory on Monday at Time Warner Cable Field.   For the second straight game, Yadiel RIvera delivered the walk off hit, a 10th inning three run homer on Sunday, and on Monday, a 9th inning RBI single.  The Rattlers trailed 7-4 in the 7th inning but tied the game to set the stage for Rivera's heroics.  Wisconsin improves to a season best 18 games over .500 at 41-23 and hit the road for a series against Clinton on Tuesday night.
