The Colorado Rockies are set to face off against the Miami Marlins once again, this time in a four-game series at Coors Field. The matchup brings back memories of their previous encounter three months ago when the Rockies opened the 2026 season in Miami, only to suffer a disappointing sweep at the hands of the Marlins. Each game was a nail-biter, with Colorado losing all three by just one run, including a heart-wrenching walk-off 4-3 defeat in the finale.

As the Rockies (33-50) look to flip the script, they come into this series having gone 5-5 over their last ten games, but struggling at home with an 18-22 record this season. In contrast, the Marlins (44-40) are riding a wave of momentum, boasting an impressive 8-2 record in their last ten contests. The Marlins’ success can be attributed to their adept use of small ball tactics and their remarkable MLB-leading total of 92 stolen bases.

On the mound for Colorado will be Sean Sullivan, making his fourth Major League start. The 23-year-old lefty, who is still searching for his first win against the Marlins this season, carries a record of 0-2 with an 8.25 ERA. Sullivan’s journey has been a mixed bag; after a promising debut where he threw three scoreless innings against the Athletics, he faltered in his second start, allowing eight runs on nine hits, including two home runs, in just four innings against the Chicago Cubs. However, he showed signs of improvement in his most recent outing, giving up three runs on five hits while walking five and striking out three in five innings against the Boston Red Sox.

Opposing him will be Sandy Alcantara, the 2022 NL Cy Young Award winner, who has been in stellar form this June. With an 8-4 record and a 4.01 ERA, the 30-year-old right-hander has posted an impressive 2.60 ERA over the month, alongside a perfect 5-0 record, 29 strikeouts, and just six walks across 34.2 innings. His ability to dominate on the mound will be critical as Miami aims to extend their winning streak.

Fans can catch the action starting at 6:40 p.m. MDT, with coverage available on Rockies.TV and the Rockies Radio Network at 850 AM/94.1 FM, as well as KNRV 1150 AM for Spanish listeners. The stage is set for what promises to be an exciting series.
