Andy Murray says he put in one of the worst performances of his career in a «demoralising» first-round Monte Carlo Masters defeat to Alex De Minaur. The 35-year-old produced 26 unforced errors and failed to earn a single break point as he collapsed to a 6-1 6-3 defeat on his first appearance at the tournament since 2017. Ad Murray’s miserable display sealed back-to-back first-round tournament exits, following a straight-sets loss to Dusan Lajovic at the Miami Open, and he was furious with his efforts in Monaco.
