PHOENIX -- If Mark Reynolds knew how to diagnose his problem, it wouldn't be a problem.
The Diamondbacks 24-year-old third baseman admits he may be a feast-or-famine player, but in the end, his streaks all even out.
"If I figured it out, I wouldn't be streaky," said Reynolds. "I don't know what it is. Some days I feel good, some days I don't. I don't know why. If I had a good day, I try to do everything the exact same way the next day. I really don't know what it is."
Reynolds went 3-for-3 with a home run, two doubles and a walk on Monday night against the Brewers, raising his batting average to .258. Entering Tuesday, his 17 homers and 52 RBIs ranked first on the team, as well as his .509 slugging percentage.
With his last homer, Reynolds matched his career high, set in last year's rookie season -- although it took him 91 fewer at-bats to reach the plateau.
But there are times when Reynolds has struggled mightily at the plate, including two games this season where he had four strikeouts. His average has hovered around .250 the entire season, but from June 22 through Monday, Reynolds was hitting at a .360 clip (9-for-25).
"I try to do the same thing every day and try to go through the same routine," Reynolds said. "That's why it's hard to play up here, because they figure you out. That's why it's so tough to get here."
Reynolds said it is somewhat of a problem for several of the D-backs' hitters, adding it could be due to youth and inexperience. He had never been streaky before he was recalled last season and was consistently a .300 hitter at every level.
"We're all still kind of adjusting," Reynolds said. "I think that once we have more at-bats, more times in pressure situations, we will all get more consistency."
On Monday, D-backs manager Bob Melvin said that it looked like Reynolds had finally started to find his stroke.
"He had a couple off games on the road trip, but leading into that, he swung the bat well and had some real good games," Melvin said. "[Last night] he was on everything, whether it was straight or curveball or whatever. He seemed to have good swings on everything."
