The surging New York Yankees begin a three-game set with the AL Central-leading Detroit Tigers tonight. With both lineups filled with sluggers along a pair of struggling starters on the hill, my MLB picks expect a run to be scored in the first inning of their clash.

Here are my best NRFI bets for Tuesday, September 9.

NRFI/YRFI bets for September 9

Tigers at Yankees: YRFI (Play at Thrillzz)

The New York Yankees have a stacked lineup that leads the majors in OPS (.784) and first-inning run percentage (37.1%). Today, they host the Detroit Tigers, who will send struggling right-hander Casey Mize to the mound. 

Over the last two months, Mize has pitched to a 6.53 ERA with 1.55 WHIP across nine starts. The Yankees respond with sophomore Will Warren, who has also looked vulnerable on the hill. 

Warren is in the Bottom 10th percentile in hard-hit rate and exit velocity while sitting in the Bottom 15th percentile in barrel rate. He has an expected ERA of 4.48 and will struggle navigating a Tigers lineup that ranks seventh in the majors in xwOBA (.438).

Reds at Padres: NRFI (Play at Thrillzz)

The Cincinnati Reds have an OPS of just .691 on the road while ranking 28th in first-inning run percentage (24.7%). They'll have a tough time getting going against Michael King, who the San Diego Padres just activated from the IL.

King has a 2.81 ERA with a .206 OBA this year. He's been dominant at the beginning of games, pitching to a 0.82 ERA with an OBA of .149 through the first two innings. King hasn't played in a month, so he'll be on a pitch count, but he should get through the first inning unscathed.  

The Reds will give the pill to Zack Littell, who has logged a 3.81 ERA with a 1.14 WHIP through 28 starts. Littell has been excellent in the opening frame, posting a 2.89 ERA with an OBA of .208.

Another reason to like the NRFI bet is the 10 mph breeze blowing towards the infield at pitcher-friendly PETCO Park today.

Cardinals at Mariners: NRFI (Play at Thrillzz)

The Seattle Mariners have been crushing the ball on the road while struggling to generate runs at T-Mobile Park. They are 26th in the majors in OPS (.690) and 28th in first-inning run percentage (20.3%) at home.

Tonight, George Kirby, who has pitched to a 3.16 ERA with an OBA of .228 at home, takes the hill. 

Kirby should deal against a St. Louis Cardinals lineup that is last in the majors in OPS (.650) and runs per game (3.75) since the All-Star break.
