After Charlie Sifford's death, an outpouring of support on Twitter

Charlie Sifford -- called golf's Jackie Robinson after becoming the first African-American golfer to play on the PGA Tour -- died on Tuesday night. He was 92.

Sifford was awarded the Presidential Medal of Freedom last November from President Barack Obama, one of only three golfers to receive the honor (Jack Nicklaus and Arnold Palmer are the others). It's a sad day for the game, and once news of his death started spreading throughout social media, people from all corners of the world started paying tribute.
