Nationals the Top Consensus Play Wednesday

There are only two Major League Baseball sides seeing better than 70% of the concensus plays Wednesday.

The Nationals are seeing the most at 74%.

The Rockies are seeing 73% of the action.

The line on Washington has fallen from -173 to -141, an indication that the books really want you to bet on the Nationals.

The question is: Do you really want to bet on the Marlins?

PITCHING MATCHUP: Nationals LH Patrick Corbin (6-5, 3.90 ERA) vs. Marlins RH Zac Gallen (0-0, 1.80)

Corbin halted a three-start losing streak last time out against Philadelphia, striking out eight and limiting the Phillies to one run and four hits over seven innings. He had been hit hard in his previous three turns, giving up 20 runs and 22 hits over 12 2/3 innings, but he pitched a masterpiece against Miami on May 25 with a four-hit shutout -- the second of his career. Corbin is 2-1 with a 3.72 ERA in seven starts versus Miami and has held Starlin Castro hitless in eight at-bats.

Gallen was drafted in the third round of the 2016 draft by St. Louis and got a chance to face the Cardinals in his major league debut on Thursday, striking out six while allowing one run and five hits over five innings of a no-decision. "It was awesome," Gallen said. "I mixed my pitches pretty well. We threw a lot of off-speed and kept them on their toes." The 23-year-old was dominant at Triple-A New Orleans, posting a 9-1 record and 1.77 ERA in 14 starts prior to his promotion.

Colorado might be a safer bet with a line that's moving up from -126 to -143.

PITCHING MATCHUP: Rockies RH German Marquez (7-3, 4.32 ERA) vs. Giants RH Jeff Samardzija (4-6, 4.23)

After allowing four earned runs or more in four of his previous five starts, Marquez yielded two runs (one earned) with eight strikeouts over eight innings in a no-decision against the Los Angeles Dodgers last Friday. The 24-year-old native of Venezuela owns a 5.70 ERA in nine home starts this season compared to a 3.02 mark in eight outings away from Coors Field. Marquez is 1-3 with a 4.75 ERA in six career starts versus San Francisco.

Samardzija received ample run support last Friday against Arizona and picked up the victory despite allowing five runs on nine hits over six innings. The 34-year-old Indiana native posted a 2.53 ERA over his first six starts this season but has struggled of late, losing five of his last seven starts. Daniel Murphy is 10-for-20 with a home run against Samardzija, who is 5-6 with a 3.71 ERA in 18 career games (14 starts) versus Colorado.
