What happened: American League competitors convene under the direction of John Schneider for the annual contest. Red carpet arrivals and pregame introductions precede the first pitch.

Why it matters: The exhibition pauses the 162-game regular season schedule at the midsummer break. Front offices use the four-day intermission to evaluate roster needs ahead of the July 30 trade deadline.

What to watch: Regular-season competition resumes on Friday with fifteen series on the slate.
