Both the Texas Rangers and Oakland Athletics will play with black ribbons on their uniforms for Friday night’s game, in memory of Shannon Stone, the Rangers fan who died after falling over a railing reaching for a ball tossed his way by Texas’ Josh Hamilton during Thursday night’s game.

In fact, A’s beat writer Susan Slusser tweets that the teams will continue to wear the ribbons throughout their weekend series.

Also, Slusser tweets about Josh Hamilton’s status:

Washington said Hamilton wanted to be out there, so he is in lineup. #Athletics #Rangers

This has to be a very difficult day for Hamilton, who was simply trying to do something nice for a man and his son, something that is done dozens of times every day at major league ballparks, flipping a souvenir into the stands. This is a tragic accident being mourned by baseball players, management and fans today. The game will go on, but tinged with sadness.
