Anton won 6-1 6-3. His extra power forced the Finn to go for more than what he was comfortable with, so Anton's only danger was a bit of complacency and carelessness which crept into the second set.
Jacks match is a higher standard, which the American has just won the first set on a tiebreak (7-1). Jack will rue missing a setpoint at 5-4 when Tristan slipped at the net (to his credit he made a remarkable recovery shot, but should still have been passed)
Momentum now with Boyer, who breaks at the third attempt in game 1 of the decider. The American looks like a good competitor and has already won two tight 3 setters here so Jack needs to fight back quickly.
