Colorado's September: An 8.18 ERA, a Nine-Game Road Skid, and 100 Losses in Sight

The most damning number from the Rockies' last week isn't in the standings. It's 8.18.

That's Colorado's staff ERA over its past 10 games, per the team trend data, paired with a 1.678 WHIP and 4.27 walks per nine. Over the last five games alone, the ERA ticked even higher while the team went 1-4. That's the through-line of the week in Denver: a young, thin pitching staff hitting the September wall at the worst possible time, and it's now threatening to swallow the last 10 games of the season.

The staff is out of gas, and the numbers are ugly

Colorado's season-long 5.66 ERA ranks 30th in MLB, 0.36 runs worse than the 29th-place Athletics (5.30). The bullpen sits at 4.57 with 9 blown saves against just 19 holds. A staff already stretched all year — 21 pitchers used, 980.2 innings — is now walking everyone and paying for it.

Look at the injury list and the workload problem gets clearer. Chase Dollander and Jose Quintana are on the 60-day IL alongside McCade Brown, Pierson Ohl and Welinton Herrera. Jeff Criswell and Sean Sullivan are on the 15-day. When a rotation loses that many arms, September becomes a live audition with real hitters standing in the box.

Thursday's home finale against San Diego puts that on display. Tanner Gordon gets the ball against Michael King, and Gordon's profile is a microcosm of the issue: a 5.878 ERA and 4.408 K/9, with a home ERA of 8.036 against a 3.00 road mark. The split data even flags a 9.72 day ERA. Coors Field has not been kind.

The offense has one bright spot — and one big worry

Hunter Goodman remains the story of Colorado's season: 38 home runs, 81 RBI, a .529 slugging percentage, and 11 more homers than any other catcher in baseball. But the last 30 days tell a different tale — a .206 average, .662 OPS and four home runs over 18 games, with a 24 percent strikeout rate.

Now add health. Goodman left a recent Rockies-Padres game with an apparent injury after a sliding triple, and while he doesn't appear on the current injury report, any absence would remove the only consistent power threat from a lineup that already strikes out 1,301 times. The one offensive jolt in the last week came from Cole Carrigg, whose 4-for-5, two-homer, five-RBI night snapped San Diego's eight-game winning streak.

What it means for the rest of 2026

The Rockies are 4-10 in September with a minus-27 run differential, and they've dropped nine consecutive road games dating to late August. At 56-96, four more losses would deliver a 100-loss season — a benchmark this franchise hasn't hit in years. The road split (16-31, .340) says the schedule isn't going to bail them out.

Thursday's market context reflects all of it: San Diego is -164 with Colorado at +138, and the total sits at 10.5. Notably, eight of Colorado's last 10 games have gone over, and all of the last five have — a direct byproduct of that 8.18 ERA.

None of this is a reason to do anything with your money. It's a reason to watch how the front office uses the final 10 games. With Kris Bryant on the 60-day IL and Kyle Karros just reinstated from concussion protocol after Ryan Ritter was optioned, the evaluation period is already underway. The question for October isn't who wins these games. It's which arms survive them, and whether Goodman's bat is healthy when the offseason planning starts.
