The Milwaukee Brewers pulled the plug on the Brett Lawrie experiment Tuesday after insufficient progress was made during 3½ months of the unique project.

The Brewers signed the former major-league infielder to a minor-league deal at the outset of spring training with the understanding that he needed extensive physical rehabilitation after suffering leg and hip injuries with the Chicago White Sox in 2016. He was released by that club the following spring.

The hope was that Lawrie, 29, would eventually get back on the field with a minor-league affiliate but the process never advanced to that point, so it was mutually decided to part ways, according to Brewers president of baseball operations David Stearns.

“Everyone tried their best,” Stearns said. “Brett gave it a very good effort. I know our training staff worked hard. At this point, it just made sense to move on.

“At the front end of this, we all agreed on a tentative time frame, with certain benchmarks. We weren’t quite able to meet some of those benchmarks. So, we thought now was the right time to allow Brett to move on and allow us to devote our resources to other players.”

Asked which side decided it wasn’t going to work, Stearns said, “There was an understanding going in that there were certain benchmarks we wanted to meet. When we couldn’t get over a few of those hurdles, this was the mutual understanding.

“We had benchmarks in terms of certain rehab goals, in terms of competition goals. We just couldn’t quite get there in the time everyone thought we were going to. This allows Brett to move on with his life and career.

“He put a lot of effort into this. He spent a lot of time working with our group in Phoenix. So, it’s certainly understandable for there to be some disappointment (for Lawrie)."
