Sam Reeder had 19 points and Courtney Macklin 13 points and 10 rebounds as No. 17 El Dorado upset No. 3 River City 48-45 in a girls basketball game tonight in Placerville.
The win clinches at least a share of a fourth consecutive Sierra Valley Conference championship for coach Pat Winter's Cougars (18-7, 11-1).
River City (24-2, 10-1), which defeated El Dorado 42-32 Jan. 20 in West Sacramento, will need to beat Vista del Lago on Friday to gain a co-championship with El Dorado.
El Dorado is 47-1 in league during the last four seasons.
