The way the Rockies’ series finale against the Athletics started, it looked like a win in Sin City just wasn’t in the cards. Tomoyuki Sugano gave up four runs in the first inning and eight across five frames, but Colorado’s high-octane offense didn’t flinch as they barreled their way to a 23-9 victory over the A’s on Sunday afternoon at Las Vegas Ballpark. It was the most runs the Rockies have scored in franchise history, breaking the previous mark of 20, which had been done four times (most recently on July 24, 2024 vs. Boston). The Rockies also walloped a single-game season-high six homers and 24 hits to go along with five walks. Hunter Goodman (5-for-6 with two homers and four RBIs), Kyle Karros (4-for-6 with two RBIs), Ezequiel Tovar (3-for-6), Troy Johnston (2-for-5 with three runs scored and four RBIs) and Willi Castro (4-for-6 with two homers and seven RBIs) all contributed to the offensive outburst. Castro, an eight-year veteran, had never had more than three RBIs in a single game before Sunday’s record-breaking performance. In all, the Rockies had seven players with multiple hits and six with multiple RBIs. Despite his line, Sugano picked up his seventh win of the season. Colorado rattled off a combined 15 hits -- producing nine runs -- in its first two games against the A’s in Las Vegas. The Rox came away from those with a pair of defeats knowing a high-scoring game may be needed to pull off a win, and they turned around and produced a performance for the ages. “I don’t ever foresee a game like this. This is an outlier, big time,” manager Warren Schaeffer said. “But I always feel like something good is going to happen when our team takes the field. I feel like the way we’ve been conducting our at-bats, and the way we’ve been going about our business, the progression of that as the year has gone on has consistently gotten better.” The historical significance of this performance will be talked about in Colorado for some time.
