What happened: The Colorado Rockies are marking the July 4th holiday weekend by tying their home slate to America250, the nationwide commemoration of the country's 250th anniversary. The club is promoting a themed celebration built around baseball in the Mile High City over the Independence Day stretch.

Why it matters: Holiday weekends are among the biggest draws on the MLB calendar, and clubs lean on themed promotions to boost attendance and fan engagement. Tying the gate to a national milestone gives Colorado a hook for one of the summer's marquee weekends.

What to watch: Watch for the Rockies' holiday-weekend home crowd and any additional America250-themed activations tied to the Independence Day slate.
