Wells hit home runs in three successive games once before this season, the first three of the season against the Rangers in Arlington, when he had four in the three-game series.
He says it is all in the hands.
"[I'm] just trying to make consistent contact," Wells said. "[I'm] working in BP, working in the cage, just trying to get back to using my hands."
It is something he was doing well earlier in the year.
"I kind of got away from it," Wells said. "It's been a learning experience, just being able to trust my hands again. It's been a while since I've been able to. It's been a learning year, hopefully I'll learn a lot from it and get better next year."
The two home runs on Tuesday gave him 27 for the season. Wells hit 19 by the end of June. The four home runs he has already in September equal his total for July and August combined.
"Ups and downs, not consistent enough," Wells said of his season so far. "There's been some encouraging times and there's been some times when you you think you have it figured out and you don't. I've been around this game for a long time and I'm still learning things. I think I still have a lot more that I can accomplish in this game."
Wells went 0-for-2 with two walks in Wednesday's 8-1 loss to the Rangers.
