Casper Ruud meets Karen Khachanov in the ATP Rome Masters quarterfinal at Stadio Centrale on red clay. The matchup brings the No. 9 ranked Ruud against No. 15 Khachanov, with Rome seeds listed at 23 and 13 respectively. Both arrive with three wins this week and a clean ticket to the last eight in a best-of-three sets format. On paper, the market leans toward Ruud, but the serve-and-return numbers add a few layers.

Serve snapshot: similar accuracy, different outcomes

Both players are landing a similar share of first serves so far, with Ruud at 65.5% and Khachanov at 66.0%. The difference shows up after the toss. Ruud has won 77.4% of first-serve points and a strong 69.4% behind his second delivery. Khachanov sits at 71.2% on first serve and 54.8% on second.

Aces and errors? Khachanov leads in raw power with 17 aces across three matches, while Ruud has 6. Double faults are under control on both sides, with Ruud at 4 total and Khachanov at 6.

Return pressure and clutch numbers

Ruud has faced only three break points in three matches and has been broken once, saving 66.7% in that sample. He has converted 10 of 22 break chances himself, a 45.5% clip. That suggests steady pressure without needing tiebreak insurance.

Khachanov has lived on the edge more often, facing 22 break points but saving 90.9% and getting broken just twice. He has converted 9 of 18 chances on return, exactly 50%. He also won the only tiebreak he played, which could matter if sets stay tight.

What the odds and totals say

Pre-match odds list Ruud as a clear favorite at 1/5, with Khachanov at 7/2. The total games line is set at 21.5, priced around 5/6 for both Over and Under. That points to a competitive two-set match as a likely baseline, with room for a longer contest if Khachanov’s serve escapes a few sticky moments.
