Rockies vs. Diamondbacks: How to Watch the May 21 Series Opener

Rockies vs. Diamondbacks: How to Watch the May 21 Series Opener

Posted by Caspian Delamere On 22 May, 2026 Comments (0)

It’s a classic West Division clash on Thursday night, with the Arizona Diamondbacks hosting the Colorado Rockies at Chase Field in Phoenix. The series opener kicks off at 9:40 p.m. Eastern Time (7:40 p.m. local Mountain Time), setting the stage for a four-game set that runs through Sunday. For fans wondering how to catch every pitch, the options range from dedicated streaming services to over-the-air broadcasts, depending on where you’re sitting.

The stakes are decent, though the records tell a tale of two different seasons so far. The Dbacks sit at 25-23, hovering near .500, while the Rockies are struggling at 19-31. It’s not just about winning; it’s about survival in a competitive division. Here’s the thing—baseball is unpredictable. One hot streak can flip a season upside down. That’s what makes this matchup worth watching, even if one team looks like the clear underdog.

Pitching Matchup: Freeland vs. Kelly

The duel on the mound features Colorado left-hander Kyle Freeland, pitcher for the Colorado Rockies against Arizona right-hander Merrill Kelly, pitcher for the Arizona Diamondbacks. On paper, neither arm is having a stellar year. Freeland carries a 1-4 record with a lofty 6.00 ERA, suggesting he’s been giving up too many earned runs per nine innings. Kelly isn’t much better, sitting at 2-3 with a 7.62 ERA. Oddly enough, when both starters are struggling, the game often comes down to bullpen depth and timely hitting.

Turns out, the Diamondbacks’ offense is doing its job despite the pitching woes. They rank 11th in Major League Baseball in runs scored, tallying 221 total runs—that’s an average of 4.6 runs per game. It’s not elite production, but it’s enough to keep them in contention. For the Rockies, the question is whether they can generate enough power to exploit these mediocre pitching matchups.

Key Players to Watch

If you’re looking for stars to track, the Diamondbacks have a few standouts. Infielder Ildemaro Vargas is on fire, boasting a .331 batting average, .351 on-base percentage, and .530 slugging percentage through 41 games. He’s already hit 7 home runs and driven in 32 runs. Then there’s outfielder Corbin Carroll, who brings speed and power with a .285 average and 7 homers. His .395 on-base percentage shows he knows how to get on base, which is crucial in tight games.

On the Rockies side, the lineup has been quieter. But players like Ketel Marte (.235 avg) and Nolan Arenado (.278 avg) provide veteran presence. Arenado, in particular, offers consistency with 25 RBIs and 7 home runs in 45 games. Shortstop Geraldo Perdomo is still finding his rhythm, batting .224, but his defense remains solid. The twist here? If Vargas keeps up his pace, he could be the difference-maker in this series.

How to Stream and Broadcast

For viewers in the Rockies’ television territory—which includes Colorado, Wyoming, Utah, New Mexico, and parts of Nebraska, South Dakota, and Idaho—the broadcast landscape is specific. In-market fans can watch via ROCKIES.TV, available through DIRECTV channel 683, Xfinity/Comcast channel 1262, Spectrum channels 130 or 445 (depending on location), and Fubo streaming service. TDS TV+ also carries the games on channel 243 for some areas.

But wait—if you’re outside that territory, you’ll need standard MLB.TV. Just note that MLB.TV All Teams subscribers cannot stream Rockies games if they’re located in Colorado; they must purchase the separate Rockies.TV package. It’s a blackout rule designed to protect local broadcasters, and it catches many casual fans off guard.

Radio fans have it simpler. Rockies games are exclusively on KOA 850 AM & 94.1 FM throughout the 2026 season. Diamondbacks radio coverage is on Arizona Sports 98.7 FM, La Campesina 101.9 FM, and 860 AM. No alternative English-language partners are listed for the Rockies, making KOA the go-to spot for audio-only listeners.
