After getting rained out on Saturday night, Pella High and Oskaloosa are finally, we hope, set to do battle in the Class 4A regional semifinal on Monday night. The Indians swept the regular season series, but Pella’s 1 – 0 win over Grinnell last Thursday proved that it’s hard to beat a team four times in a season. You can hear Monday night’s game exclusively streamed live on KNIAKRLS.com. Pregame coverage starts at 5:15 p.m. with the first pitch at 5:30 p.m. The start time is earlier due to Oskaloosa being the host site for a Class 1A regional final that same evening.
