Welsh racer Cameron Nelson recorded his strongest British F4 weekend to that point at Zandvoort, taking two fourth places while Rodin Motorsport won all three races.
JHR Developments' Nelson also secured Rookie Cup honours in Sunday's reverse-grid contest. Ethan Lennon won that race for Rodin, ahead of George Proudford-Nalder and Alba Larsen, who achieved her best British F4 finish in third.
The race featured two Safety Car periods before a final-lap sprint. Nelson emerged fourth, narrowly ahead of Hitech's Scott Kin Lindblom and Theo Palmer.
Dries Van Langendonck won the later race from pole, giving Rodin a clean sweep of the meeting and taking his fourth victory of the season. Kin Lindblom and Palmer completed the podium, while Nelson again finished fourth.
For the Welsh driver, consecutive results near the front provided a substantial step forward within a weekend otherwise dominated by the championship-leading Rodin operation.
