"I can't explain it," Hardy said. "It feels good. I think I'm just relaxed and comfortable up there, and it seems like I'm getting a lot of pitches to hit.
"When things are going bad, it seems like you hit the ball hard and everything gets caught. When things are going good, it seems like you don't have to hit the ball hard because they'll find holes."
Hardy's found holes all week, and for several weeks before. He's coming off a recent 16-game hitting streak during which he hit .448.
"He's good, but that's an understatement," manager Ned Yost said. "He's been very, very good. He's right on everything, hitting for power, hitting doubles, hitting singles and clutch hitting. He's hitting everything.
"I don't know how much better it gets than right now, for any player. It really doesn't get much better than the way he's swinging right now."
Hardy, who's played each of his four Major League seasons with the Brewers, had four hits against the Diamondbacks on Thursday and four more against the Pirates on Friday. He hit home runs on Tuesday, Thursday, Friday and Sunday, including two each on Tuesday and Sunday.
Hardy finished last week with a .600 (18-for-30) batting average, five doubles, six home runs, a .625 on-base percentage, a 1.367 slugging percentage, 18 hits and 41 total bases. The 25-year-old added eight runs and 12 RBIs.
"This is definitely up at the top with my hottest streaks ever," said Hardy, who is the only Brewers player among 30 nominated for this week's award.
Tourneau, the world's largest watch store, will award Hardy with a luxury Swiss timepiece, suitably engraved, in recognition of his accomplishment as the National League Player of the Week.
