The sun was starting to set and the air began to thin as the two sides emerged for the second-half. The Royals were quickest to adapt and managed to take the lead under fortunate circumstances with a cross that deflected in off a Palace shirt.
They doubled their lead shortly after the hydration break, with Sentnor scoring from close range after being set up by Betfort inside the box.
Palace pushed for a goal to halve the deficit as the game went on, but the Royals managed to add a third through a free-kick. Defender Kaleigh Riehl rose highest to divert a looping header in.
It wasn’t to be for Palace in the end, as the hosts ran out 3-0 winners. Kaminski and her side will now turn their attention to further pre-season fixtures ahead of their inaugural WSL campaign.
