With the D-backs facing left-handers their previous three games, the left-handed-hitting Wheeler, who batted eighth on Thursday against the Mets, received three days off to start the week after appearing in three games over the weekend.
The time away from the lineup forced Wheeler, who played virtually every day while in Triple-A, to keep his body active in different ways.
"I think I've done a good job of tiring out my body so it's felt like I have been playing," he said. "I've been taking 20 minutes of ground balls, running back and forth, I've been doing a running program and throwing more, it's just more pregame stuff to get the legs tired and arm going."
The rookie's extra activities caught the attention of D-backs manager Kirk Gibson.
"He's been working his tail off," Gibson said. "You want to make some little adjustments early on because I don't think you just throw him to wolves. He's done a lot of work and he's ready to play."
Besides being coached up when not in the lineup, Wheeler has had to deal with the initiations that come with being a rookie in the clubhouse.
The 24-year-old walked into the clubhouse Thursday sporting a new haircut, barbered by veteran teammate J.J. Putz. The closer wanted to give Wheeler the hairdo of another teammate, but they instead settled on a trim job.
"I negotiated the clipper guard up a little bit, they were going to give me a four on the side and I got it up to a seven so it doesn't look that terrible," Wheeler said. "They were going to give me the (Henry Blanco) haircut. I said I cannot do that but they got me anyways."
In addition to the haircut, Putz also engineered Wheeler's walk-up song to switch to "Candy Girl" by New Edition, a tune the young player was familiar with but not particularly a fan of.
"When I was walking up, I was confused because I didn't recognize it right away, so I thought there might be a theme of the day like in the minors," Wheeler said. "Then I was listening and I heard it, and I was like 'Oh my god.' I remembered it playing in J.J.'s locker before the game."
But like a true good sport, Wheeler has taken all the pranks in good fun and sees it as part of the experience of playing in the Majors.
"The guys have been awesome," he said. "It's been everything I expected and I'm starting to get more comfortable every day."
