What happened: The Astros announced that single-game tickets for the second half of their schedule go on sale Tuesday. Fans can begin purchasing seats for the remaining home dates at that time.

Why it matters: Putting the back half of the calendar on sale gives Houston's fan base a first crack at the highest-demand dates as the club fights to climb back into the playoff race. With the standings still tight, ticket timing matters for a team trying to build momentum at home down the stretch.

What to watch: Watch for the on-sale to open Tuesday, with the highest-demand home dates likely to move first.
