Can siblings win tour events on the same Sunday?

Probably not, but Nicholas Thompson and Alexis Thompson have each placed themselves in a position to challenge on Sunday.

Nicholas Thompson has had rounds of 68 and 67, a nine-under par total that places him tied for second, one back of leader Vaughn Taylor, in the PGA Tour's Turning Stone Resort Championship.

His sister, Alexis, a 14-year-old amateur, has had rounds of 65 and 69, 10-under par, that places her in a five-way tie for the lead at the Navistar LPGA Classic.
