"Right now, I guess it's in my court," Klein told the website. "But with a guy this young, it's hard to figure out what the right numbers would be. It would be good, be nice if it was possible to do. But I don't know. It's way, way on the drawing board."
Segura's value has only increased since that offer was made. The shortstop homered in his first at-bat in Tuesday's 4-3, 12-inning loss in Pittsburgh and later added an RBI groundout. He came into the game leading the National League in batting average (.368), hits (50), multi-hit games (17) and stolen bases (13).
He is earning $492,000 this season, just north of the league minimum salary, and entered the year with only 65 days of MLB service. That means he will continue to draw a salary near the league minimum through the end of the 2015 season, then be arbitration-eligible but still under Brewers control from 2016-18 before reaching free agency.
The Brewers acquired Segura from the Angels at last year's non-waiver Trade Deadline, along with two Minor League pitchers, for free-agent-to-be right-hander Zack Greinke.
Said manager Ron Roenicke about Segura: "I don't know. Those kind of things are gambles, they are looking at a guy who you are going to have to feel is going to be good for a long term, and with a first year or second year player those are tough decisions. I know nothing about it.
"What you see from him this year, he's doing everything right, we didn't see that player last year. This is a great player, this is a guy that I don't want to ever take him out of the lineup. I keep talking about I want to get him a day off and he plays so well I can't take him out, and he doesn't want out. He's one of the best players in the league."
