In fact, it pulled a record-low number, according to Awful Announcing:

Tuesday night’s MLB All-Star Game on Fox drew a 6.2 overnight rating, a record low overnight. Last year’s game drew a 6.5 overnight, same as 2017, and the previous record low came in 2016, when the game in San Diego drew a 6.2 overnight.

Not a baseball problem, however. People just don’t care about All-Star games in this day and age, as evidenced by the ratings for the Pro Bowl and recent NBA and NHL events.

According to Sports Media Watch, Pro Bowl 53 (ESPN/ABC) pulled a 5.1 rating, down 4% from last year. The NBA All-Star Game pulled a combined 3.8 on TNT and TBS, down 12% from 2018.  And the NHL All-Star Game hit its worst number of the past three years, earning a 1.1 rating on NBC.

I watched a bit of the All-Star Game. It was okay, though only two runs in the first five innings was a bit of a snoozer. Could have used some earlier action.

But yeah, people are just not very interested in meaningless ASGs in 2019. There are other things to watch and other ways to spend your time instead of watching a glorified exhibition.
