Overview

• João Fonseca exited Cincinnati with a 6-3, 6-4 loss that extended his run of uneven results since winning the Argentina Open in February.
• The 18-year-old Brazilian has seen his ranking slip to world No. 52 from a career-high No. 47 last month, even as he remains the highest-ranked player in his age group.
• Terence Atmane converted three of 13 break-point chances and won 79 percent of his first serves to secure the upset in straight sets.
• Atmane’s Cincinnati breakthrough caps a rise that includes ITF and Challenger titles and a maiden Grand Slam appearance at the 2024 Australian Open.
• Tennis analysts warn that such volatility is common for teenage pros in their first full seasons and note that Fonseca’s trajectory mirrors early struggles of Roger Federer.
