(AP) — Brooks Koepka chose to withdraw from the Travelers Championship because his caddie tested positive for the coronavirus. The four-time major champion feels even worse for his younger brother. Chase Koepka is trying to make it on the Challenge Tour in Europe, just like his brother once did. He made it through a Monday qualifier for a PGA Tour event. Both withdrew out of caution from being in close contact with someone who tested positive for the virus. Brooks Koepka says he feels responsible for putting his brother in that position. His brother had no place to stay Monday night after qualifying so Koepka had him stay in his house.
