What happened: The Chicago Cubs signaled the start of play with a first-pitch announcement from the club's account. The post marks the opening of the day's contest at the ballpark.

Why it matters: First-pitch markers are routine game-day touchpoints rather than developments in themselves, but they open the window on a slate that shapes the Cubs' position in the standings as the regular season rolls through June.

What to watch: Watch for in-game updates and the final line once the result is official.
