Best MLB prop bets Sept. 1: Bet on Brandon Lowe with a platoon advantage vs. Mariners

MLB prop bets

Most of MLB’s Labour Day action is coming in the afternoon, but one of my prop bets targets the evening slate.

Today’s MLB props narrative: Brandon Lowe is a good pick to mash when there’s a right-hander on the mound, and I’m buying in on his platoon advantage Monday night.

Check out my top MLB prop bets for Sept. 1, featuring a prediction on Carlos Correa.

MLB prop bets

Best bet: Lowe over 1.5 total bases (+110)

There’s a notable platoon advantage that I’m happy to tap into with this pick, as the left-hitting Lowe faces Seattle right-hander Luis Castillo.

  • Lowe vs. RHPs (2025): .290/.349/.557 slash line
  • Castillo vs. LHBs (2025): .289/.363/.491 slash line

Lowe has hit 24 of his 28 homers off righties, while Castillo’s opponent SLG jumps 131 points when a left-hitting player digs into the box.

These guys matched up three weeks ago, and Lowe greeted Castillo with a solo home run in the top of the first inning. All told, Lowe is 3-for-8 with two extra-base hits vs. Castillo.

August was a brutal month for Castillo, as he allowed 18 runs on 33 hits (6.66 ERA) over five starts.

Key stat: Lowe is 12-10 vs. this prop in his past 22 games. He has nine home runs in that span.

MLB quick pick

Correa over 0.5 RBI (+130): Correa has recorded an RBI in four of nine games as the Astros’ cleanup man, and he’ll be back in that spot this afternoon against the Los Angeles Angels.

After a white-hot start in his return to Houston at the start of August, Correa cooled a bit over the back half. Still, there’s a lot to like here.

  • Correa is 13-for-25 (.520) with a triple and two doubles vs. Angels starter Yusei Kikuchi.
  • Houston has a ton of experience — and success — against Kikuchi. The lineup as a whole is batting .288 with a .562 SLG in 146 at-bats. More traffic on the basepaths would mean more RBI opportunities for Correa.
  • Kikuchi is coming off his worst start of the year (six earned runs over 4.0 innings). He has a 5.40 ERA over his past 10 starts.
