After all that offense in the first two games, an outburst should not have been surprising in game three, but then again, no one is ever ready for a game with 40 total runs, 38 hits, nine homers and two grand slams.
Eight of the nine homers were hit to either center or right, where the wind was blowing out at 21 mph.

Bobby Boyd led the way for the Jethawks, going 4-for-7 with nine RBIs, including a grand slam.
"I think I hit a grand slam in high school," Boyd told MiLB.com. "I had faced [Stockton pitcher Rob Huber] the inning before, so I knew what he had. He tried to get ahead with a fastball and I reacted to that. I put a good swing on it. I can only hope to have another night like this, especially as a leadoff man. Honestly, I think I'll leave the RBIs to our big hitters. I'll stick with getting on base and setting the table for them. It's hard enough to do that."
In a game with that much offense, Boyd was hardly the only player producing at the plate. Jason Martin was a perfect 5-for-5 with six RBIs, while Ramon Laureano and Bryan Muniz each drove in four, Muniz on the strength of a pair of homers.

"Honestly, I'm still kind of shocked to see all of the hits, the runs and just how many guys had good games," said Boyd. "The game just kept going on and on and on. It was crazy. I've never been a part of anything like that."
The JetHawks fell short of the Cal League record for most runs in a game -- the Fresno Cardinals scored 34 in 1947 -- but the 29 runs were a franchise record. Lancaster scored in five of their eight trips to the plate, putting up four in the second, seven in the third, eight in the fourth, three in the sixth and seven in the seventh.
On the other side, James Harris and Seth Brown each drove in a trio of runs for the Ports.
Three Ports pitchers allowed seven or more earned runs, while the only pitcher to escape the game without allowing a run was Stockton's Melvin Mercedes, who began the game in left field. He worked the final 1 1/3 innings, allowing two walks while striking out one.
