Carlos Alcaraz made a solid start to the ATP Finals on Sunday with a 7-6 (7/5), 6-2 win over Alex de Minaur, while former champion Alexander Zverev got underway with a straight-sets win over Ben Shelton.
The defeat marked a second time in 23 months for Erasmus to get one over his French counterpart, who had visited him while he was working with the Irish province between 2016 and 2017.
