What happened: The Washington Nationals teased that Kolko and Franny will be calling balls and strikes for tonight's game. The post is a light, fan-facing broadcast bit rather than a roster or game-result announcement.

Why it matters: It fits a stretch of fan-engagement posts from the club, including an All-Star voting push. These promotions are aimed at driving fan participation and broadcast interest during the regular season.

What to watch: Watch the Nationals' broadcast tonight to see the segment play out, and for any follow-up All-Star voting promotions from the club.
