Cardinals manager Mike Matheny and assistant athletic trainer Chris Conroy took a mound visit after Martinez retired Logan Schafer on a shallow fly ball to left field. Martinez had allowed a double to Scooter Gennett to open his 29th start of the season.
After a brief visit, Martinez left the mound with Conroy. Martinez walked slowly to the dugout and held his glove over his face for most of it. Tyler Lyons entered in relief.
This was expected to be Martinez's penultimate start of the regular season. He was seeking his 15th win and had held Milwaukee to one run over 15 innings this season.
