When Gervinho won the fifth race Monday, he won for trainer Carla Gaines and owner Keith Brackpool. One of the reasons those connections drew interest is that Gaines was the subject earlier this meeting at Del Mar of a barn investigation by the California Horse Racing Board. Multiple sources reported that two of Gaines’ horses tested positive for an undisclosed banned drug. And John Harris, who owns horses that Gaines trains, confirmed Gaines’ barn was checked by CHRB investigators.
