Rockies Ride Power Surge into Matchup with Skidding Nationals

Two teams at the bottom of the standings are heading in completely opposite directions. The visiting Colorado Rockies, powered by the long ball, will look for their first four-game winning streak of the season on Wednesday night as they face the spiraling Washington Nationals.

A Franchise Record Power Display

The Rockies are playing with a newfound confidence, fueled by an incredible power surge. They tied a franchise record with seven home runs in their 10-6 victory on Tuesday, with six different players going deep. After being one of the worst MLB teams for most of the season, they are playing a respectable .500 baseball over the last two weeks.

“We could have let the start of the season weigh on us and beat us down,” one Rockies player said. “We’re starting to play with more confidence… and expect to win the game.”

“We’re Not Going to Quit”

Meanwhile, the Nationals are at rock bottom, having lost 10 consecutive games. Their offense continues to struggle, though they’ve shown some late-inning fight that has fallen just short. Despite the skid, manager Dave Martinez is sending a defiant message.

“Nobody wants to lose 10 in a row. No way,” Martinez said. “But we’re not going to quit. We’re going to keep fighting. That’s who we are.”

A Battle of Struggling Starters

Wednesday’s pitching matchup features two arms looking for a good outing. The Rockies will start German Marquez (2-8, 6.62 ERA), who has pitched better than his record suggests lately and is coming off a solid start against Atlanta.

The Nationals will counter with lefty Mitchell Parker (4-7, 4.84), who is on a four-start losing streak and is trying to bounce back from his worst performance of the season. This duel between two pitchers needing a win will be a focus on the scores and odds board. The psychology of a long losing streak is a major factor, a topic explored in our expert betting guide.
