What happened: Masyn Winn leads National League shortstops this season in Fielding Run Value, Defensive Runs Saved and arm strength. Winn also joined MLB Central to discuss his defensive work and how pitching earlier in his career helped shape that arm.

Why it matters: Leading both Fielding Run Value and Defensive Runs Saved points to run prevention that goes beyond a single highlight throw. Adding top arm strength to those marks strengthens Winn's case as one of the position's standout defenders this season.

What to watch: The next step is whether Winn can hold those league-leading defensive marks through the rest of the season. Updated leaderboard movement will show if the gap stays intact.
