Sparks said that those two schools are standing out in his top three, with nearby Cal the other school in the mix, and the leader for him.
"I'm open to everything right now, but Cal is still the favorite for me," said Sparks.
This weekend, Sparks will take an unofficial visit to Berkeley for the Bears home game with Washington State.
Sparks said he wasn't rushing to make a decision, choosing instead to take some time before making his commitment.
"Sometime after the season, I'll probably made my announcement, but not any time soon," said Sparks.
So far, Merced is 8-0 and ranked #3 by GoldenStatePreps.com in Northern California. Sparks has played a major role in that start, with 30 catches for 761 yards and 11 touchdowns. He's had four 100-yard games, including a 7-catch, 173-yard, 2-touchdown performance against Madera and then a four touchdown showing against Turlock.
"This team is a lot different than last year (when Merced lost in the CIF-San Joaquin Finals)," said Sparks. "After we had gone down to L.A. (to play Crenshaw) and won, we knew things were different."
