Chicago Cubs 6, Milwaukee Brewers 8

The standings say Milwaukee has created separation in the NL Central. The numbers behind Wednesday’s matchup explain why.

At 90-56, the first-place Brewers bring a nine-game lead over the second-place Cubs into American Family Field, and they do it with a profile built more on run prevention than raw offensive firepower. Chicago has actually been the slightly more productive lineup over the full season, averaging 5.30 runs per game to Milwaukee’s 5.03 while posting the better slugging percentage (.430 to .399) and OPS (.769 to .739). Even in the last 10 games, the clubs have scored at nearly the same rate, with Milwaukee at 5.50 runs per game and Chicago at 5.40.

The more meaningful separation shows up on the mound.

If the probable starters hold, Milwaukee sends Logan Henderson into a favorable statistical matchup. In 15 starts, Henderson has a 2.48 ERA, 0.79 WHIP and 10.0 strikeouts per nine innings, along with just 1.5 walks per nine. Those are standout rate numbers, and they line up with Milwaukee’s overall pitching advantage. Kevin Gausman’s underlying profile is more competitive than his 4.38 ERA suggests — his 3.58 FIP sits much closer to Henderson’s 3.27 than the ERAs do — but Henderson still owns the better mark in ERA, FIP, WHIP, strikeout rate and walk rate.

There are a couple of narrower counters for Chicago in the starting matchup. Gausman has allowed home runs at a slightly lower rate, 1.16 per nine to Henderson’s 1.30, and his quality-start percentage is essentially even at 48% versus 47%. But overall, Milwaukee’s starter comes in with the cleaner statistical line.

That edge doesn’t disappear if the game gets deep into the night. The Brewers also hold the better bullpen numbers, carrying a 3.67 relief ERA, 1.21 WHIP and 9.6 K/9. The Cubs’ bullpen has been less efficient by each of those measures, with a 4.32 ERA, 1.33 WHIP and 8.0 K/9.

So the shape of the game is fairly clear. Chicago has the more forceful season slugging profile and scores a bit more often. Milwaukee, though, has paired the division’s better record with stronger run prevention from both the probable starter and the bullpen. That combination is a big reason the Brewers have built first place into a cushion.

• Milwaukee enters first in the NL Central at 90-56, nine games ahead of Chicago at 81-65.
• Chicago has the stronger season offense by runs per game (5.30), slugging (.430) and OPS (.769), but Milwaukee has the edge in starting-pitching and bullpen run prevention.
• Probable Brewers starter Logan Henderson holds the advantage over Kevin Gausman in ERA (2.48 to 4.38), FIP (3.27 to 3.58), WHIP (0.79 to 1.26), K/9 (10.0 to 9.2) and BB/9 (1.5 to 2.4).
