Since June 1, the Brewers are 4th in the division (ahead of only the Cubs) and 12th in the NL in runs scored.
It is clearly the run prevention unit (2nd best in the NL) that is keeping them on target. With Yelich now out indefinitely, the pressure on run prevention is likely to ramp up. Going 3-1 on the road trip in games in which the offense produced 1, 1, 1, and 3 runs in 9 innings highlights that.
