Jason Collins delivers the ceremonial first pitch at Fenway Park

Jason Collins came out as the first active, openly-gay athlete in a U.S. professional team sport earlier this year. Soon after his April announcement, the Red Sox invited the NBA center (and former Celtic) to throw out a first pitch any time this season:

We salute you, @jasoncollins34 for your courage and leadership. Any time you want to throw out a first pitch at Fenway Park, let us know.

- Boston Red Sox (@RedSox) April 29, 2013

Collins accepted and tossed a first-pitch strike before Thursday's game against the Indians. It was a cool sports moment that was enjoyed by fans, Wally and most importantly, Jason himself:

I went from the wind up. Over the plate, right down the middle for strike 1. Thank you @redsox. #Pride #bostonstrong twitter.com/jasoncollins34…
