Round 4 - Parker has been cut under his right eye. He continued working inside where Winters dominated. The cut came from a left hook from Winters. The American will take that round.
Round 3 - Parker drops Winters with a bomb of an overhead right! Winters beat the count and then was saved by the bell. Parker should look to finish it in this round, you would think.
