Zizou Bergs - Alexander Zverev

Alexander Zverev enters Monte Carlo's Round of 16 as the heavy favourite at 1.22 odds, but his path to the quarter-finals is far more uncertain than the markets suggest. In his previous match against qualifier Cristian Garin, Zverev produced a worrying performance: 46-47 unforced errors, a lost first set (4-6), and a deficit of 2-5 in the deciding set before scraping through 7-5. For a player ranked third in the world, such error volumes and tight escapes against a much lower-ranked opponent signal genuine current form concerns heading into a matchup against an in-form underdog.
