Rocklin's three-year reign as Sierra Foothill League champions came to an end on Wednesday when Oakmont beat the No. 7 Thunder 7-3 behind the pitching of Jared Virtue and Nick Hoffman's 4-for-4 performance.
Rocklin needed to sweep Oakmont in this week's three-game series to tie No. 8 Granite Bay for first place and finish as league co-champions.
Granite Bay (19-8, 14-4), which lost two of three games to Rocklin earlier in the season, finished the regular season last week.
Rocklin (20-7, 13-5) beat Oakmont 13-0 on Tuesday and 8-0 on Thursday.
Rocklin will play No. 18 Christian Brothers (14-11-1, 10-7) 8 p.m. Thursday in the Sac-Joaquin Section Division II opener at Sacramento City College. Granite Bay will play No. 12 Ponderosa (15-11-1, 11-7) 8 p.m. Friday at Sac City.
First-round games are single elimination.
