Holy first pitch, Batman! This kid has an arm.

The tiniest superhero in the world, Batkid, threw out the first pitch for the San Francisco Giants’ home opener on Tuesday in front of a packed house at AT&T Park.

Batkid is the alter ego of 5-year-old Miles Scott, a kindergartner who has leukemia in remission. Scott captured America’s attention in 2013 when San Francisco and the Make-A-Wish Foundation threw a massive, daylong celebration for the minuscule masked vigilante.

Batkid Day occurred in November 2013, when San Francisco banded together to make young Scott’s wish come true. Local actors staged crimes in which Batkid was needed to come and save the day, including one scene in which he needed to save Giants mascot, Lou Seal. Mayor Ed Lee gave Batkid the key to the city, and even President Obama recorded a personalized message to the tiny caped crusader.

On Tuesday, Batkid entered the park in a Batmobile-painted Lamborghini, got out, and waved to the packed stadium of fans cheering for him. Accompanied by his friend Batman, he took to the mound and lined up to fire one in to Giants’  pitcher Matt Cain. His pitch took a couple bounces on the way there, but the ball got there eventually.
