But Eaton is by no means totally comfortable in the Majors just yet.
"I was talking to Eaton. He said, 'When do things get normal?,'" D-backs manager Kirk Gibson said. "It's different."
"I don't know if it's ever what you expect it to be -- you don't really know what to expect," Eaton said of life in the big leagues. "It's been a fun experience. ... I don't know if you ever expect -- well, you expect the unexpected, basically. But it's been a fun ride thus far."
That ride began in San Francisco on a night Eaton would never forget.
"The national anthem my first game in San Francisco was something. It was basically kind of the key of like, 'Wow, this is amazing,'" Eaton said. "It was loud there in San Francisco, 41,000 people just yelling and screaming, and you sit with the national anthem going off, it was giving me some chills."
That Eaton was able to push the hostile home of a division rival to the back of his mind and come up with two hits in his Major League debut made quite an impression on his manager.
"If you look at the environment he went into, his first environment: San Francisco. Night game. Very, very loud. Huge outfield. Windy, foggy, put all the elements in there," Gibson said. "[Fans are] burying him out there every inning -- that's what they do in the outfield. So, by no means would you be comfortable."
But if Eaton was uncomfortable, it certainly hasn't showed. Eaton has three multi-hit showings in his first four games, including a career-high three hits in Saturday night's win.
"As a ballplayer, if you didn't think that you were going to have that kind of success, you wouldn't be here," Eaton said. "Everyone wants to get on the ground running. ... When you want something and it happens you shouldn't be surprised."
"Hitting the ground running" is an apt metaphor for what the speedy Eaton has done since joining the D-backs. He's roamed center field in place of the injured Chris Young, while also wreaking havoc on the basepaths and with infield hits.
"I love his style of play," Gibson said. "I don't know that we've ever had a prototypical leadoff hitter since I've been here, and that's what you would hope that he can do: Be a spark plug at the top. One of his ex-teammates told me yesterday: 'He's the type of guy who'd be the last guy I'd ever want to play against.' He's very disruptive."
