From the airport, take 405 North,stay in the right lane because you immediately veer right onto the 55 North. Take the 55 North ( about 5 miles), to the 5 North. Stay on the 5 N for about 5 miles to the 57 North, the first exit is either OrangeWood or OrangeThorp, can't remember, but you'll see the stadium on the left as soon as you get on the 57. Also the transition from the 5 to the 57 puts you on the 57 on the left hand side and you need to get over for the exit pretty quick. If you miss the OrangeWood exit, the next one is Katella and that will work also. Good luck, and stop by the Asterisk booth in the pits and say hi if you get a chance.
