TOURNAMENT SLATE Eight tournaments across 102 matches span the clay-dominated April 21 card, with WTA and ATP Madrid anchoring the schedule at the Masters 1000 level. Clay surfaces account for 81 matches versus 21 on hard courts, reflecting the spring European clay season. Prize funds range from the $8.9M Madrid events down to the $56.7K Abidjan Challenger, with qualification rounds and lower-tier ITF events filling the undercard in Oeiras, Rome, and Shymkent.

D. Singh squares off against M. Alkaya in Abidjan's 1/16-finals on hard court, with the 349-ranked Alkaya installed as a heavy favorite at 1.11 odds despite the 214-ranking gap. Singh, sitting at 563 on the ATP ladder, carries 5.50 odds into what shapes as a notable underdog spot. The encounter offers value considerations given the substantial ranking differential and Alkaya's tight pricing.

April 21, 2026 is wrapped. 102 encounters completed across 8 tournaments. 101 favourites prevailed (99.0%), 1 underdog — prevailed, 37 encounters went three sets, 46 tiebreaks played. Full breakdown below.

Tuesday, April 21 delivered 104 markets across eight tournaments, with clay dominating the slate at 82 of those matches spread through WTA Madrid, ATP Madrid, Savannah, Shymkent, and beyond, while the two hardcourt events in Gwangju and Abidjan provided the day's sharpest storylines. Favourites were virtually untouchable across the 102 completed ties, converting at a remarkable 99.0% clip with just one upset on record — I. Simakin turning over A. Bolt at Gwangju at odds of 2.14, the three-set scoreline of 6-7 6-3 1-6 offering little comfort to backers of the favourite. The match card itself was eventful in volume if not variance: 37 of 102 completed matches went to three sets, 46 tiebreaks were played, and 19 sets ended in a bagel, painting a picture of a day simultaneously tight and dominant. M. Giunta wrapped up the Abidjan Challenger title in efficient fashion, dismissing A. Fenty 7-6 6-2 to claim the $56,700 event's top prize on hard courts. On the CLV front, R. Noguchi posted the most notable closing-line movement at Gwangju with a +2.8% edge, the day's lone meaningful signal in an otherwise settled market where favourites left the books little room to breathe.
