Marlins vs Nationals MLB Betting Preview
Miami Marlins Betting Preview
The Miami Marlins hand the ball to right-hander Janson Junk, who should serve as a good fade candidate. Junk has struggled at the MLB level, and 2026 has followed that trend.
Through 20 appearances, the right-hander is 6-8 with a 4.21 ERA and a 1.30 WHIP. His underlying metrics are equally poor.
Entering this matchup, Junk owns a 4.20 xERA and a .258 xBA. He also ranks in the bottom half of the league in average exit velocity, strikeout rate and hard-hit rate.
Junk's woes are likely to continue against the Washington Nationals. Over the past three meetings, he is 0-1 with a 6.60 ERA and a 1.40 WHIP.
Washington Nationals Betting Preview
From the other side, the current Nationals roster owns a .439 slugging percentage and a .506 expected slugging percentage in 45 combined plate appearances against Junk. Washington has quietly been one of the best lineups in baseball this year, ranking first in runs scored per game, seventh in hits per game, first in slugging percentage and third in OPS.
Clearly, hitting has not been an issue for the Nationals. Their sub-.500 record is reflective of the club's poor pitching, including the performance of left-hander Andrew Alvarez.
Slated to start in this contest, Alvarez carries a 2-6 record, a 3.72 ERA and a 1.35 WHIP into this matchup. His underlying metrics are even worse.
This season, Alvarez owns a 4.59 xERA and a .259 xBA. He also ranks in the bottom third of the league in average exit velocity, walk rate and hard-hit rate.
Marlins vs Nationals Pick, Betting Analysis
Both starting pitchers are poor, and the Nationals boast one of baseball's best lineups. The main threat to the over is Miami's run production, but there are two reasons to be optimistic about its ability to contribute.
First, Alvarez is, analytically, one of the worst pitchers in MLB. Second, the Marlins can manufacture runs through small ball.
This season, Miami ranks 11th in hits per game, sixth in batting average, sixth in on-base percentage and 11th in OPS.
Pick: Over 8.5 (-117 | Play to -125)
