On a balmy Monday night at Nationals Park, the Washington Nationals turned a tight contest into a laugher, pounding the Colorado Rockies 13-3 to push the visitors' losing streak to a season-high seven games. The outcome was shaped by a decisive five-run fifth inning that saw the Nationals rally from a 2-0 deficit, capitalizing on a costly error and timely hitting.

CJ Abrams, who had missed the previous four games with a sprained ankle, served as the designated hitter and made an immediate impact. After the Nationals had gone hitless through the first four innings against Rockies starter Ryan Feltner, the offense ignited in the fifth. Back-to-back singles set the stage, and Nasim Nuñez laid down a sacrifice bunt toward third base. Colorado third baseman Willi Castro fielded the ball but threw wildly down the right-field line, allowing two runs to score and tying the game at 2-2. Abrams then laced a double to right field, driving in Nuñez to give Washington a 3-2 lead. He promptly stole third and scored on a groundout by Abimelec Ortiz. Daylen Lile and Brady House followed with consecutive doubles, padding the lead to 5-2.

Cade Cavalli, who improved to 12-5 on the season, was stellar yet again. The right-hander worked six innings, scattering seven hits and striking out seven while walking none. He allowed two runs, both on solo home runs. Since the All-Star break, Cavalli has been nearly untouchable, posting a 7-1 record with a 1.98 ERA across eight starts. He has started the Nationals' last three victories, underscoring his emergence as the staff ace.

Colorado struck first in the fourth inning when Castro, who had been red-hot since the break, ripped the first pitch of the inning off the foul pole in right field for his 15th home run of the season—eight of those have come after the All-Star break. The Rockies added another run in the fifth when shortstop Ezequiel Tovar led off with a solo shot to center, his 10th of the year. But Tovar was removed from the game in the sixth inning after straining his left wrist while attempting to make a catch on a single by Jacob Young in the top half. His status for upcoming games remains uncertain.

The Nationals kept pouring it on. In the sixth, they added three more runs off Feltner, who was lifted after 5 2/3 innings. The right-hander allowed seven runs—five earned—on eight hits, with six strikeouts and two walks, falling to 5-8 on the year. A two-run seventh inning extended the lead to 10-3, and Lile capped the scoring in the eighth with a towering three-run homer, his first of the season, giving him five RBIs on the night.

Washington's bullpen held the Rockies scoreless over the final three innings, with relievers Victor Arano, Jorge Lopez, and Hunter Harvey combining for three strikeouts and no walks. The win snapped a three-game losing streak for the Nationals, who had dropped seven of their previous eight contests.

Looking ahead, the series continues Tuesday night with Washington left-hander Andrew Alvarez (2-5, 3.60 ERA) taking the mound. Colorado has yet to announce a starter for the second game after placing Kyle Freeland on the 15-day injured list Monday. The Rockies will hope to avoid extending their losing streak to eight, while the Nationals aim to build momentum after a much-needed victory.
