Best NRFI Bets Today 2026 05 15

Yankees vs. Mets - Cam Schlittler vs. Clay Holmes (7:15 PM EST)

The Mets are struggling, but the Subway Series should bring out the best in the team. Any series between these two rivals is usually filled with excitement. 

Under 0.5 Run (-140) at Caesars Sportsbook

Both the Yankees and Mets have dangerous lineups, but the pitching matchup still offers plenty of NRFI value.

Cam Schlittler has quickly emerged as one of the more intriguing young pitchers in the Yankees organization. He attacks hitters with power stuff and has done a solid job limiting hard contact early in games.’

Schlittler is 5-1  with a 1.35 ERA and a 0.81 WHIP. He is a future Cy Young winner in the American League. 

The Mets will counter with Clay Holmes, who continues to thrive in a starting role this season. Holmes generates plenty of weak contact with his sinker, which is especially important against a Yankees lineup filled with power hitters.

Both offenses are capable of scoring quickly, but this feels like a spot where the pitchers control the first inning.

Red Sox vs. Braves - Connelly Early vs. Spencer Strider (7:15 PM EST)

The Red Sox are in the danger zone facing the best team in baseball this weekend. They’re seven games under .500, and if they get swept, they can basically call the season over. 

Under 0.5 Run (-120) at Caesars Sportsbook

The Atlanta Braves continue to look like the most complete team in baseball, and Spencer Strider gives them a massive advantage every time he takes the mound. 

Strider has been dominant once again this season, overpowering hitters with elite velocity and one of the best strikeout rates in baseball. The pitcher is 1-0 with a 2.89 ERA and a 1.29 WHIP. 

Connelly Early has also shown flashes for Boston this season. The young left-hander has done a respectable job keeping hitters off balance, and he is the future of the franchise. 

The Red Sox offense continues to struggle overall, which should help Strider cruise through the top half of the first inning. If Early can avoid a mistake to Atlanta’s power bats, this NRFI has strong value.

Padres vs. Mariners - Randy Vasquez vs. Emerson Hancock (9:40 PM EST)

The San Diego Padres offense is powerful, but inconsistent early in games. The Mariners have been limited at the plates and just sent Cal Raleigh to the injured list. 

Under 0.5 Run (-130) at Caesars Sportsbook

Randy Vasquez has quietly put together a solid stretch for San Diego. He does a good job pitching to contact and limiting damage, which is important against a Seattle lineup that can be inconsistent offensively.

The Mariners will turn to Emerson Hancock, who continues to develop into a reliable option in the rotation. Hancock is 3-1 with a 3.21 ERA and a 1.01 WHIP. 

Seattle’s home park also tends to suppress offense, which adds even more value to this matchup.

Best YRFI Bets Today

  • Giants vs. Athletics - Tyler Mahle vs. Aaron Civale: Both pitchers in this contest fail to command the zone in dominant fashion. They each surrender hard contact because they’re not overpowering. Additionally, this game is played in Sacramento where the dimensions of the field resemble a minor league stadium.
