Washington Riding Offensive Momentum

The Washington Nationals tied their season high for runs and hits on Monday, pounding out 19 hits in a 15-7 victory over the Miami Marlins. It marked Washington’s third straight win and sixth in the past seven games, a stretch that has helped them build confidence despite being well out of playoff contention.

Interim manager Miguel Cairo has emphasized finishing strong and developing young talent, and top prospect Dylan Crews provided a highlight with a three-hit, four-RBI performance that included a home run. While Crews has struggled to adjust at the big-league level, nights like Monday point to the potential that made him the No. 2 overall pick in 2023.

Nationals Pitching Concerns

Mitchell Parker will get the ball Tuesday, looking to halt a long skid. The left-hander is 0-5 with a 9.28 ERA over his past seven starts and hasn’t won since July 26. Against Miami, he has a 1-1 career record and 3.86 ERA across six starts, but his 2025 numbers against them are shaky with a 7.07 ERA in three matchups.

Washington’s offense has been carrying the load, but the team’s ability to string together wins also depends on Parker stabilizing his command on the mound. For bettors weighing the odds, reviewing the MLB picks before first pitch can offer extra insight.

Marlins Struggle to Finish Strong

The Marlins have dropped six of their last seven games and appear destined for another losing season, their fourth in five years. Their pitching staff has been a major issue, allowing at least 15 runs in a game for the third time in 2025 during Monday’s loss. The team ERA sits at 4.79, one of the worst in the National League.

Even so, Miami continues to develop its young core. Victor Mesa Jr. provided a bright spot with his first career home run, which came on his 24th birthday. Manager Clayton McCullough has prioritized giving young players experience to build for the future. Fans can follow the team’s progress in the latest MLB game results

Mazur Gets the Start for Miami

Adam Mazur, still searching for his first big-league win, will make his fourth start Tuesday. The rookie right-hander carries an 0-2 record with a 5.74 ERA. He faced Washington on September 2 and allowed five runs (four earned) across six innings in a 5-2 loss.

Mazur has struggled against the Nationals overall, posting a 6.55 ERA in two career starts. With both pitchers coming in on rough stretches, Tuesday’s contest has the potential to be another high-scoring affair. For deeper betting strategies, check out the MLB expert betting guide
