Eduardo Rodriguez is about to walk into Coors Field with a 2.89 ERA and a WHIP under 1.25, which means he’s been one of the few pitchers this season who actually knows how to pitch. Tanner Gordon is about to take the mound with a 6.01 ERA and a 1.55 WHIP, which means he’s been one of the many pitchers this season who absolutely doesn’t. This isn’t a close call. This is a mismatch that should dictate how you attack tonight’s game.
The Diamondbacks are sending one of their best arms against a Colorado pitcher who has lost five of his last six decisions and is giving up almost a baserunner per inning. In September baseball, when every game matters, that gap is the entire story. Rodriguez has thrown 183 innings and kept his walks plus hits in check while striking out hitters at a respectable clip. Gordon has 100 innings of evidence that he probably shouldn’t be on the mound in games that mean something.
Arizona Diamondbacks Players to Watch
Gabriel Moreno is hitting .310 with an .871 OPS, which makes him one of the few catchers in baseball who can actually hit. Against a pitcher throwing 6.01 ERA fastballs, that becomes relevant. Moreno doesn’t chase much—his plate discipline has been the thing that separates him from just another guy with decent pop—and he’s the kind of hitter who punishes mistakes. Gordon throws mistakes. The over on Moreno’s hits total is worth chasing if it’s in the 0.5 range; he’s too disciplined to chase Gordon’s likely wildness out of the zone, which means he’s waiting for pitches to hit, and Gordon’s fastball won’t live up there.
Nolan Arenado’s .250 average doesn’t jump off the page until you remember he has 28 home runs and an .786 OPS in a season where he’s been hurt and frustrated. He’s a right-handed hitter facing a pitcher whose fastball velocity is probably sitting in the low 90s. That’s Arenado’s dinner bell. The power spike this late in the season—he’s driven in 80 runs—suggests he’s locked in for the stretch, and Gordon represents the kind of matchup where a veteran bat can do real damage. Look for him to be aggressive early in the count.
Colorado Rockies Players to Watch
Hunter Goodman has 39 home runs, which is the kind of slugging number that demands respect regardless of the context. At Coors, with Rodriguez on the mound, Goodman becomes a different proposition. Rodriguez isn’t going to leave fastballs up in the zone—his control is the whole reason his ERA is respectable—so Goodman’s power becomes contingent on getting something to hit. That’s less likely tonight. The under on Goodman’s hits is the smarter play here; Rodriguez will work around him, keep him off balance, and a disciplined pitcher versus an impatient slugger usually wins that battle in September.
TJ Rumfield has quietly had a solid year at .296 with decent pop, but he’s a left-handed hitter facing Rodriguez, who has handled lefties effectively all season. The matchup advantage swings hard toward the pitcher. Rumfield’s .830 OPS looks solid in a vacuum, but it flattens considerably when you’re facing a guy who’s kept his WHIP below 1.25 for nearly 200 innings. This is not a night where Colorado’s offense gets extended at-bats.

A pitcher with a sub-1.25 WHIP against a Colorado lineup that’s hitting .246 as a team suggests Diamondbacks hitters are going to see better pitches than Rockies hitters tonight.

Arenado’s power line carries value at Coors against Gordon’s mediocre fastball. On the Colorado side, Hunter Goodman’s hits under is worth pursuing against a pitcher with genuine control.
