Alex Rodriguez scored some serious dad points by tagging along with his 15-year-old daughter to an Olivia Rodrigo concert -- even though he wanted to catch some zzz's instead.
The legendary slugger documented their outing Wednesday night in an, inadvertently, hilarious IG video ... as he admitted he was exhausted from filming all day, but was prioritizing some quality time with Ella at the Miami gig -- despite clearly not knowing who the singer is.
In fact, he tells his followers he's at a "Rodrigo" concert .
