"At least it was something in my weight class," Wise said.
The injury affected Wise's ability to throw his best pitch, his changeup, because the ball comes off of his middle finger when he throws it.
Wise was unavailable to pitch Monday and Tuesday against the Cubs, but after playing catch on Tuesday he hoped to be able to pitch on Wednesday.
"It was better today than it was yesterday," said manager Ned Yost. "We'll work around it. It's nothing major."
This wasn't the first bad-luck injury Wise has faced this season. In San Diego on May 10, Wise had to make a trip to the clubhouse and strained his shoulder when his hand slipped off a rail in the bullpen.
Wise isn't the only Brewer to have strange injuries. Jeff Cirillo hurt his ankle by slamming his helmet on it after just missing a home run.
"At least his was game-related, I was going after a salad," Wise said. "[Bullpen catcher] Marcus [Hanel] wants to call me 'Bubble Boy' so I don't get hurt."
Other freak injuries include Atlanta pitcher John Smoltz's scalding himself by ironing a shirt he was wearing, and then-Toronto outfielder Glenallen Hill's crashing into a glass table while having a nightmare about being covered in spiders.
Wise pitched a scoreless ninth in the Brewers' win in Kansas City on Friday. He had allowed seven runs in his previous four outings.
"I was just happy to put up a zero," Wise said.
Happy about Jackson: Without injured starters Ben Sheets and Tomo Ohka, the Brewers have combined to go 4-14 in those spots in the rotation. Three of those wins have come with left-hander Zach Jackson on the mound.
Jackson pitched into the sixth on Tuesday, allowed three runs and laid down two successful sacrifice bunts that led to runs.
"As long as we can get that win I'm happy," Jackson said. "Anytime I can help the team it feels great."
For the season, Jackson is 1-0 with a 4.70 ERA and has 17 strikeouts against three walks.
Yost said he's been pleased with the 23-year-old rookie and hasn't really been surprised.
"You can see he's got a lot to work with," Yost said. "He's got some intangibles, and he's very pitchable."
For the time being, Jackson has brought calm to what was a revolving door of young pitchers, many of whom Yost said may have been overwhelmed.
"He keeps us in the game," Yost said. "That's important for all of our starters. Keep your club in the game."
On the farm: Four Nashville Sounds were named Pacific Coast League All-Stars. Outfielders Tony Gwynn Jr., and Nelson Cruz, catcher Mike Rivera and starting pitcher Ben Hendrickson made the team.
