Following the trades of Gerardo Parra and Jonathan Broxton today, they found that they had some available roster space available. One of those spots was filled by calling up Tyler Thornburg earlier today. The other was filled with a waiver claim, as the Brewers were awarded a claim on Preston Guilmet.

Guilmet hasn't seen much time in the majors yet, but what he has seen hasn't been good. In 21 career major league innings, he has posted a 6.43 ERA and 4.24 FIP. On the flip side, though, his minor league numbers are very good. This season, he has posted a 1.95 ERA over 32.1 IP between three teams. The strikeout rate is nice at 7.71 K/9, but there's also some control issues with a walk rate at 3.00 BB/9. So, there is some promise here.
Guillmet primarily throws three pitches. His fastball averages at 89 MPH and he throws it 39.3% of the time. He also has a slider that average 82.8 MPH and is thrown 45.3% of the time, and a cutter at 88.5 MPH that accounts for 14.6% of his pitches.
The Brewers have the roster space for now, so taking a flier on a guy like this isn't a bad idea. If he puts things together, the Brewers could end up with six years of control on him. If not, there's nothing lost by letting him go. Overall, it's a decent pickup for them.
