Poor defensive play continues to haunt the Butler BlueSox.

In Tuesday’s Prospect League baseball game at West Virginia, three Butler errors led to seven unearned runs in a 13-10 loss to the Miners.

The Sox held a 6-2 lead entering the bottom of the fifth, but a Butler error aided West Virginia’s nine runs as the Miners sent 13 men to the plate in the frame.

Butler’s offense produced 12 hits, including a 3-for-4 night from Tanner Murphy, who scored twice and drove in a run.

James Meeker, Patrick Ferguson and Pavin Parks each added two hits. One of Parks’ hits was a triple.

Mark Gross took the loss, allowing eight runs (four earned) on 10 hits in 4 1/3 innings pitched. He struck out five and walked two.

The Miners (5-8) again play host to the BlueSox (6-7) tonight.
