One of the most intriguing baseball betting options is the “run first inning” market, where you can wager on whether there will run scored in the opening frame.
The Detroit Tigers are set to wrap up a three-game set against the San Diego Padres tonight, and my MLB picks expect one of their pitchers to get rocked.
Check out the rest of my free NRFI and YRFI bets for Saturday, March 28.

Twins at Orioles: YRFI/ (+104)
Minnesota Twins starter Taj Bradley pitched to a 5.05 ERA over 142 2/3 innings last year. He struggled early in games, posting a 5.94 ERA with a .271 OBA through the first two innings.
Bradley could be in trouble against a Baltimore Orioles offense that should improve after adding Pete Alonso and Taylor Ward.
Meanwhile, Baltimore right-hander Kyle Bradish is coming off a strong season, but doesn’t have a large enough sample size for me to trust him. Minnesota also has a decent offense, provided Byron Buxton and Royce Lewis stay healthy.

Rockies at Marlins: NRFI (-142)
We got a winner by betting the NRFI prop in this matchup yesterday when these inept offenses combined for just three runs.
The Colorado Rockies were a disaster on the road last year, posting a .589 OPS with just 2.81 runs per game. Meanwhile, the Miami Marlins had a .693 OPS with 3.91 runs per game at home.
Both offenses should struggle again, and Miami’s Eury Perez looks ready to break out. The 22-year-old ranked in the 80th percentile in xERA (3.23), xBA (.203), and strikeout rate (27.3%) across 20 starts in 2025.
Perez should mow down a Rockies lineup that strikes out frequently.

Tigers at Padres: YRFI (-113)
The Detroit Tigers are handing the ball to Jack Flaherty, who posted a 4.64 ERA in 31 starts last year.
Although Flaherty possesses good swing-and-miss ability, he struggles when batters make contact. He sat in the bottom 20th percentile in barrel rate and hard-hit rate in 2025, and the San Diego Padres have a strong lineup that rarely strikes out.
Meanwhile, Friars starter Randy Vasquez is due for major regression after posting a 5.37 xERA last season. He’ll face a tough task navigating a Tigers lineup with dangerous hitters at the top.

What is a NRFI bet?
NRFI (No Run First Inning) and YRFI (Yes Run First Inning) bets add a thrilling twist to the start of an MLB game. A NRFI bet is a wager that no runs will be scored in the first inning. You're betting that the starting pitchers for both teams will get through the first inning without allowing any runs, whether by striking out batters, inducing ground balls, or through solid defensive play.
A YRFI bet is the exact opposite. You're betting that at least one run will be scored in the first inning. In this case, you’re hoping for an early offensive burst such as a leadoff walk, a timely hit, or even a home run.
NRFI and YRFI bets add excitement to the early part of a game and offer immediate gratification for bettors looking for a quick resolution.
