Upton was rewarded for his hot play of late by being named National League Player of the Week.
The 23-year-old led the Majors with 16 hits last week while batting .552 and collecting his first career walk-off home run on Thursday against the Giants.
"Just relaxing and seeing the ball," Upton said. "That's it. It's a lot easier said than done. It seems to be working so I just want to stay with it."
D-backs manager Kirk Gibson certainly made sure that the award would not go to Upton's head.
"It's a nice award, but I told him let's move on," Gibson said. "We're just getting into the season and he's been outstanding for us really since [May 29], but I caution anybody to feel like we've accomplished anything at this point. It's a good sign to see him swinging the bat so well and it will certainly help us if he continues to do that."
