The East Union boys swept the 100-meter dash and pole-vault competition Saturday in the Dave Soeth Invitational, but that was not enough to win the meet, as Sierra edged the Lancers 96-84.5, while Lathrop’s Riley Gier swept the distance races. Meet host Lathrop ran away with the girls competition 131-67 over second-place Sierra at Bennie Gatto Field.
