Even though onlookers will view the game as a way to help determine who got the better end of the deal, the people around the matchup are attempting to downplay the magnitude of one start.
"It's pretty much the same," Cahill said. "Just trying to pitch normal and not think about it too much."
"I think everyone looks forward to it, but we probably don't get caught up in it as much as the fans who have maybe rooted for both," Athletics manager Bob Melvin said. "But there's definitely some intrigue to it."
After struggling in Spring Training against the D-backs, walking seven batters in 3 2/3 innings, Parker rolls into the anticipated matchup coming off the best performance of his young career in his last start. The righty had a no-hitter through seven innings and ended up holding the Rangers to one hit over eight innings.
"I feel a lot more comfortable now than I did then. It was Spring Training, and this time it counts," Parker said. "I feel like I know myself a little better, and I know the guys around me better. Kurt [Suzuki, catcher] and I have developed a good relationship, and I trust everything he says."
Cahill also is pitching well, he tossed a shutout against the Padres in his last start.
The 24-year-old who spent three seasons with Oakland is excited to see old friends more than anything.
"I went to dinner last night with [Brandon McCarthy]," he said. "My fiance is hanging out with some other Oakland families. I'm sure I'll see them around, too."
