EDGE Analysis
Winker went 3-for-3 with a double, one run and one RBI to begin Friday's contest, but he was replaced by Nick Senzel in the top of the sixth inning. The severity of the injury isn't yet clear, but Tyler Naquin could fill in as the left fielder if Winker is forced to miss additional time.
