The Western Kentucky softball team’s four-game series at Marshall has been postponed due to a positive COVID-19 case in the Hilltoppers’ Tier 1 testing group and subsequent contact tracing.

The Hilltoppers were scheduled to open Conference USA play against the Herd starting Thursday with a noon game, play a doubleheader Friday and conclude the series Saturday in Huntington, W.Va.

WKU is scheduled to host Eastern Kentucky in a 6 p.m. game April 7, before heading to Middle Tennessee to open C-USA play with a four-game series starting April 16.

The Hilltoppers are currently 15-4 overall and have won five straight games, with the latest coming 2-1 in nine innings against No. 7 Kentucky on March 24. WKU also had a game against Lipscomb scheduled for March 30 canceled due to scheduling changes at Lipscomb.
