They brought "Fan Cave West" to Chase Field as the pool presence Monday and Tuesday, and after "having a blast," they now head back to Manhattan. On Thursday, it will be time to start watching regular-season games again, on their way to 2,430 games watched.
"It's a great way, if I gotta get out of the Cave, to come to my second home in Arizona," O'Hara said. "I've been visited by Curtis Granderson and David Price, other players, celebrities, and I got to do interviews. All the great people who are here for the All-Star break, it's just been outstanding.
"I get a lot of questions -- people asking me, 'Is it really a dream job?' How am I liking it. By and large, one of the coolest things about baseball fans is, they are good people. They realize it is just a game, and a bunch of people applied for this job and auditioned, and it could have gone to anyone, so I was really lucky. I'm trying to let them see a little bit of what it's like every day for me."
Wagner was surrounded during the Home Run Derby by bikini-clad fans and Budweisers at the pool. Robinson Cano, Prince Fielder and the gang sent plenty of baseball shrapnel their way.
"It's been a blast," Wagner said. "We've really had a good time. 'Fan Cave West' was a great idea. It's hard to believe the season is half-over, but we're just getting started."
They brought "Willie in the Window" -- a stand-up version of the popular Willie Mays paper mache statue back in the real Fan Cave. They brought the green manual scoreboard, which shows how many games the duo has watched so far and how many remain.
Wagner said his highlight was when a certain Hall of Famer wandered into the pool area during the day on Monday, not sure if he was in the right place.
"I'm standing there, and I see a guy walk through here and I do a double-take. It's Ernie Banks," Wagner said. "I got a moment I'll always remember."
