Ungur was playing a sharp, relatively clean match, and had 6-4 5-*4, 40-30. Souza hit a big serve to hold on, and it got to a tiebreak where there were some great rallies, which Ungur won being the more creative and offensive player. Had 6-*3 in the tiebreak, and at *6-5 missed a regulation BH winner at basically point blank range in the frontcourt, and that was essentially the end of the match. The fourth game in the third set was a fight, and after 5 break points Souza broke serve, and broke Ungur's will with it.
This is another match where the better overall player doesn't get the job done but the one who wants it more wills themselves to victory. Great win in the end for Feijao saving 4 MPs.
