I think the Brewers biggest need on offense is a left handed power hitter who can be put in the fifth spot between Adames and Hoskins against RHP. Having Frelick in that spot, as the Brewers often have, is far from ideal.
I am hoping that Mitchell can stay healthy and show that he can fill that spot.
I also think it's important for the Brewers to avoid having someone who only has value as a DH, because they need that spot to take some of the wear and tear off of Yelich, Contreras, and Hoskins while keeping their bats in the lineup as often as possible.
The offense since June 2, when they completed the 5-1 homestand against the Chicago teams, has been pretty stagnant. They have averaged just 4,26 runs per game, which is 12th in the NL during that period. The Brewers were second in MLB with 5.15 runs per game on June 2, but they have now fallen to 8th at 4.80 RPG.
Fortunately, the Brewers run prevention unit has remained solid, allowing the team to go 19-19 since June 2 despite the offense's problems. Hopefully the break will help the hitters return to the production they had in the first two months of the season.
