Chicago White Sox 6, St. Louis Cardinals 5

On the season, the White Sox have been the steadier team. In the last 10 games, the Cardinals have been the hotter offense. That tension gives Saturday’s matchup at Busch Stadium some shape before the probable starters even take the mound.

Chicago enters at 75-72 and sits first in the AL Central, while St. Louis is 73-75 and fourth in the NL Central. The White Sox have also been a little better across most of the season-long offensive categories, averaging 4.68 runs per game to the Cardinals’ 4.56, with an edge in slugging (.405 to .386) and OPS (.723 to .703). St. Louis has the slightly higher batting average, .244 to .235, while the clubs have been essentially even in on-base percentage.

But the recent scoring trend points in the other direction. The Cardinals have averaged 6.50 runs over their last 10 games, compared with 3.30 for the White Sox, and that recent difference is large enough to stand out. It does not erase the broader body of work, but it does change the feel of the matchup.

The probable pitching matchup adds another layer. Sean Newcomb brings the stronger run-prevention profile for Chicago, with a 2.71 ERA, 2.93 FIP and 1.13 WHIP in 83 innings. He has also done an excellent job limiting home runs, allowing 0.22 per nine innings. Kyle Leahy’s numbers are solid as well for St. Louis — a 3.41 ERA and 3.57 FIP across 132 innings — but Newcomb has the statistical edge in ERA, FIP, WHIP and home-run rate.

Leahy does have a few points working in his favor. He has made 27 starts to Newcomb’s four, holds a small edge in strikeouts per nine, and has been sharper with his control, walking 2.6 per nine compared with Newcomb’s 3.1. He also owns the higher quality-start rate, 21 percent to 0 percent, though that comparison comes from very different starting workloads.

If the game gets to the late innings close, the White Sox have a modest bullpen advantage by season numbers. Their relievers carry a 4.19 ERA, 1.32 WHIP and 8.2 K/9, compared with 4.55, 1.34 and 7.5 for St. Louis.

So the clearest pregame contrast is this: Chicago brings the better full-season résumé, especially on the mound, while St. Louis comes in with the more productive recent offense. With lineups still unconfirmed, that balance is what makes this one interesting.

• The White Sox hold the stronger season profile: better record, slightly better overall offense, and a modest bullpen edge.
• St. Louis has been the hotter recent offense, averaging 6.50 runs over its last 10 games versus 3.30 for Chicago.
• Probable starter Sean Newcomb has the better season run-prevention numbers, while Kyle Leahy brings more starting workload and a higher quality-start rate.
