DENVER (Interstat) — TJ Rumfield broke out of a slump with four hits and four runs batted in, leading the Colorado Rockies to a 10-3 victory over the Cincinnati Reds on Saturday afternoon at Coors Field.

The Rockies pounced early, sending 10 batters to the plate in a four-run second inning that broke the game open. Colorado’s first baseman delivered the decisive blow two innings later, a two-run homer in the sixth that put the game out of reach. The win improved Colorado to 40-60, while Cincinnati dropped to 44-53.

Rumfield, who had gone 1 for 10 in his previous three games, finished 4 for 5 with a home run and four RBIs. His two-run shot in the sixth inning off Reds reliever Julian Garcia extended Colorado’s lead to 10-2 and capped a seven-run outburst over the first six frames. The blast was his 13th of the season.

Colorado starter Tomoyuki Sugano earned his ninth win against four losses, working 6 1/3 innings while allowing three earned runs on six hits and striking out three. He threw 98 pitches and departed with a 10-2 lead after Jose Trevino’s solo homer in the seventh trimmed the margin.

Reds starter Rhett Lowder took the loss, falling to 3-7. He lasted just 1 2/3 innings, allowing six runs on eight hits with one strikeout and no walks. The right-hander was lifted after giving up a two-run single to Jake McCarthy that capped a four-run second.

Cincinnati’s Jose Trevino was a bright spot, going 3 for 4 with two home runs and two RBIs. He homered in the third inning and again in the fifth, both solo shots to left-center field. His second homer cut the Rockies’ lead to 8-2. Trevino also singled in the ninth.

The Rockies jumped on Lowder from the start. Jake McCarthy led off the first inning with a double and scored on a double by Cole Carrigg. Rumfield followed with an RBI single, giving Colorado a 2-0 lead after one frame.

In the second, Brett Sullivan tripled and scored on a bunt single by McCarthy. Mickey Moniak singled home McCarthy, and Rumfield added an RBI single to make it 5-0. Willi Castro’s run-scoring single pushed the lead to 6-0.

The Reds got on the board in the third when Trevino led off with a home run. Elly De La Cruz followed with a triple but was stranded.

Colorado answered in the bottom half. Edouard Julien doubled and scored on a groundout by McCarthy, and Moniak singled home Ezequiel Tovar to make it 8-1.

Trevino’s second homer came in the fifth, but the Rockies responded again in the sixth. With one out, Carrigg walked, and Rumfield launched a 1-2 pitch from Garcia over the right-center wall to make it 10-2.

Cincinnati scratched across a run in the seventh when Noelvi Marte doubled, Dane Myers walked and Nathaniel Lowe singled to center to score Marte, cutting the deficit to 10-3.

Colorado’s bullpen closed the door. Brennan Bernardino struck out three in a perfect eighth, and Zach Agnos worked a scoreless ninth while allowing one hit.

The Rockies finished with 14 hits, led by Rumfield’s four. Moniak had two hits and two runs scored, and McCarthy drove in two runs. Carrigg doubled and scored twice.

Cincinnati managed nine hits. Trevino led the way with three, including two homers. De La Cruz tripled, and Spencer Steer doubled in the eighth.

For the Reds, Garcia worked 2 2/3 innings of relief, allowing two earned runs on two hits while striking out two. Pierce Johnson pitched a scoreless seventh, and Sam Moll followed with a hitless eighth, striking out one.

The game was played in 2 hours, 24 minutes before an announced crowd of 31,585 at Coors Field.

The series finale is set for Sunday afternoon. Cincinnati then travels to Seattle for a three-game set beginning Monday, while Colorado hosts Washington for a four-game series starting Monday.

For the Reds, the loss snapped a one-game winning streak after they beat Colorado 7-2 on Friday. Cincinnati had lost six of its previous seven games before that victory.

Colorado, which had lost five of six entering the series, evened the three-game set at one win apiece.

The most important sequence occurred in the bottom of the second inning. With the Rockies already leading 2-0, Lowder faced the heart of the Colorado order. After Julien grounded out, Sullivan tripled to right field. Tovar struck out, but the Rockies then strung together four consecutive hits. McCarthy bunted for a single to score Sullivan. Moniak lined a single to center, moving McCarthy to third. Carrigg singled to right, scoring McCarthy. Rumfield then hit a soft ground ball to right field that scored Moniak and sent Carrigg to third. Castro drove in Carrigg with a single to right, making it 6-0. The rally chased Lowder after 1 2/3 innings and effectively decided the game. Colorado added two more runs in the third to push the lead to 8-1, and the Reds never seriously threatened after that.

Rumfield’s performance stood out given his recent struggles. Over his previous three games, he had gone 1 for 10 with no extra-base hits. Saturday marked his first multi-hit game since July 10, when he went 2 for 2 against San Francisco. His four RBIs tied a season high.

Colorado’s attack was balanced. Seven of the nine starters recorded at least one hit, and six drove in at least one run. The Rockies’ bullpen combined for 2 2/3 scoreless innings, allowing two hits while striking out four.

The Reds’ pitching staff, which had held Colorado to two runs the previous afternoon, could not replicate that success. Lowder was tagged for six runs, and the Rockies added four more against the bullpen. Cincinnati struck out seven times overall.

Colorado’s defense turned one double play and did not commit an error. Cincinnati committed no errors but had several hard-hit balls caught by Rockies outfielders.

The game was the second of a three-game series at Coors Field. Colorado won the season series opener in April, taking two of three in Cincinnati. The Rockies were 1-2 against the Reds entering Saturday.

The Interstat game simulator had projected a final score of Cincinnati 5, Colorado 4. Interstat’s ELO system gave Cincinnati a 58.30 percent probability to win. The Reds were installed as pregame favorites with a spread of minus 1.5. The combined total of 13 runs went under the over-under line of 12.5.
