Sahaja Yamalapalli vs Anna Rogers

This is a first-round WTA 125K Newport match between Sahaja Yamalapalli and Anna Sinclair Rogers, with the winner advancing to the round of 16. Polymarket, Kalshi and Azuro all list the moneyline, and each side resolves cleanly to whichever player advances (retirements and disqualifications count; walkovers split 50-50 on Polymarket). The three books disagree on who is favoured, which is unusual for a match this close. Polymarket's main moneyline currently prices Anna Rogers at 60.0% versus Sahaja Yamalapalli at 48.1%, making Rogers the aggregated favourite. Kalshi leans the other way, with Yamalapalli at 58.0% and Rogers at just 49.0%. Azuro sits closer to Kalshi, showing Yamalapalli around 61.4%. That produces an 11-point cross-platform spread on Rogers between Polymarket and Kalshi — wide for a single tennis match and a sign that liquidity is still finding a level, with Kalshi carrying by far the most volume at roughly $295k versus Polymarket's $52k. Secondary Polymarket markets on the same match are almost coin-flips (Yamalapalli 52.5% / Rogers 47.5% on one line, 51.5% / 48.5% on another), reinforcing the picture of a genuinely tight matchup rather than a clear favourite. Totals markets skew toward the over on games, but under 2.5 sets sits at 76.0% on Polymarket, implying a straight-sets result is widely expected. The cross-platform takeaway: books agree the match is close but disagree on which player has the edge, with Kalshi and Azuro backing Yamalapalli while Polymarket's headline line favours Rogers.
