Dimers published its best bets for Tuesday, April 21, 2026, and the model’s Madrid Open play on martin landaluce was one of the numbers it said offered value. The predictive engine flagged under 22.5 total games at -115 odds, while also noting a 58% probability that translated into a 4.5% edge.
The picks sheet was marked accurate as of 10:32 PM ET and was built from Dimers’ analytics model rather than a traditional handicapper’s writeup. In the same slate, the site identified value on over 20.5 total games in Kamilla Rakhimova vs. Anhelina Kalinina at +100 odds, with a 57.4% probability and a 7.4% edge.
The April 21 list did not stop there. Dimers said Penguins vs. Flyers over 5.5 goals carried a 6.8% edge at +102 odds, NY Red Bulls ML at -120 odds showed a 6.1% edge, Ducks vs. Oilers over 6.5 goals had a 6.0% edge with a 51.5% probability, and Kimberly Birrell ML at +136 odds had a 5.7% edge.
That breadth matters because the Madrid Open matchup sits inside a wider betting card, not an isolated recommendation. Dimers’ approach is to rank plays by model edge, which puts the under 22.5 games angle in the same framework as the hockey, soccer and other tennis selections posted for the day.
The one friction point is that the top Madrid note points in opposite directions depending on how the market is framed. Dimers’ model found value on over 22.5 total games at -115 odds, but it also said a 58% probability produced a 4.5% edge for under 22.5 total games in the ATP Madrid Open matchup. The published ranking still placed the under side among the day’s value spots, a reminder that betting models can surface competing signals before the market settles on one price.
For readers following the April 21 slate, the practical takeaway is simple: Dimers’ model had a live opinion on Martin Landaluce’s Madrid Open matchup before the day was over, and it was one of several plays the system said carried an edge. The next question is whether the market moved toward the model’s numbers, or whether the prices held long enough to leave those edges intact.
