Kemba Walker has claimed his will to win is the reason for his streak of tallying up crucial points in fourth quarters this season. Walker came back on from the bench to score a sublime three-pointer as the Boston Celtics made it 10 successive wins in NBA with a 105-100 win over the Golden State Warriors. The three-time All Star netted 20 points in total on Friday, with five rebounds and five assists, while he has a 49.1 per cent shot accuracy in fourth quarters and 53.6 per cent of his three-pointers have come in the final stage of games.
