Wacha took a comebacker off the ankle and immediately exited Friday's game in the seventh inning, the Milwaukee Journal Sentinel's Todd Rosiak reports.
He gave up three runs on five hits and two walks while striking out eight in 6.2 innings before Jonathan Villar hit one back up the middle that bounced off Wacha's ankle. Look for his status to be updated later Friday night once the team releases an official injury report.
