Everyone who follows the Brewers knows that their offense has been struggling to score runs for the last few weeks. A look at the MLB stats shows the Brewers 7th in runs scored per game at 4.91 runs per game and 4th in OPS+ at 114. That looks like a pretty solid offense.
But, Brewers fans know that the positive part of those numbers comes mostly from their hot start to the season (especially the stretch in which they scored 7 runs or more per game while winning 5 of 6 games).
I wanted to quantify how dramatically different the Brewers offense has been in the last 21 games (where they have gone 10-11) compared to the first 13 games (where they went 10-3).
In those first 13 games, the Brewers averaged 6.7 runs per game and scored 3 or more runs in every game.
In the last 21 games they have averaged 3.8 runs per game while scoring 3 or fewer runs in 13 of those games
Given this run production, it is actually remarkable that they have won as many games as they have in this stretch. In their low scoring games they have been shut out twice, are 1-1 when scoring 1 run, 2-2 when scoring 2 runs, and 2-3 when scoring 3 runs.
Baseball Reference no longer has the tables that show overall league records when scoring a specific number of runs. But, based on last year's percentages, this level of production would be expected to produce about 3 wins in these 13 games.
I don't expect the Brewers to return to the level of the first 13 games for any extended period. But, if it doesn't pick up significantly it's going to be very difficult to maintain the near .500 pace of the last 3 weeks. If the pitching slips it will be "look out below".
