Our 3 best MLB player props for Tuesday, September 9

Take a look at our best bets and expert analysis below.

Prop #1: Sean Manaea Over 2.5 earned runs

+105 at BetMGM

Sean Manaea has struggled to put up consistent numbers since making his season debut. The lefty owns a 1-2 record and 5.60 ERA through 10 appearances. He’s allowed Over 2.5 earned runs in five of his last six outings. Last time out, Manaea gave up five earned runs on September 1 against the Tigers. 

Tonight, he’ll face the Philadelphia Phillies, and unfortunately, that hasn’t been a great matchup for him in the past. The Phils are hitting .284 against Manaea across 95 at-bats, with the likes of Bryson Stott, Bryce Harper, and Nick Castellanos all having success against him. 

The Phillies will score some runs tonight.

Prop #2: Bryce Harper Over 1.5 total baes

+110 at BetMGM

We’ll shift to Bryce Harper, much in part due to his track record against Manaea. He’s 6-for-16 lifetime with a home run. The slugger is batting .261 this season with 24 home runs and 67 RBI, and he does swing it better against lefties, hitting .271. 

Although Harper has cashed Over 1.5 total bases just once in his previous four games, it’s hard to ignore how well he swings the bat against Manaea. He does have a hit in three of his last four as well. This could be the perfect moment for the future HOFer to break out with a big performance. 

  • Time: 6:45 p.m. ET
  • Where to watch: NBCS-Philadelphia, SNY

Prop #3: Aaron Judge Over 1.5 total bases

-105 at BetMGM

Aaron Judge may have slowed down a little bit since returning from the IL, but his numbers are still impressive. The reigning AL MVP is batting .321 with 43 homers. He’s yet to go deep this month, but Judge has still strung together some solid performances. 

He’ll be up against Casey Mize tonight, and there’s every reason to believe this could be a big evening. Judge is 5-for-7 against Mize lifetime with two doubles and two RBI. Mize has been struggling immensely over the last couple of months, too. 

Judge has a .318 average against right-handed pitchers, and he’s going to be feeling confident in this matchup.

  • Time: 7:05 p.m. ET
  • Where to watch: YES, FDSN-Detroit
