Mookie Betts headlines Sunday’s MLB prop bets.
Today’s MLB props narrative: Betts is finding his form and has a plus matchup against Arizona Diamondbacks righty Brandon Pfaadt. I like the eight-time all-star to score and help his team avoid a sweep.
Check out my top MLB prop bets for Aug. 31, featuring prop bets on Tomoyuki Sugano and Wyatt Langford.
MLB prop bets
Best bet: Betts to score (-120)
Betts was catching plenty of flak for his production, or lack thereof, heading into the all-star break.
He was batting .244 with a sub-.700 OPS and ranked outside of the top 170 in ISO and wRC+. The veteran is slowly figuring things out in July, with a .280/.353/.400 slash line.
Those numbers aren’t great, but they’re definitely an improvement.
Betts shouldn’t have a hard time getting aboard against Pfaadt, who sports an unsightly 5.24 ERA and 1.37 WHIP. If you think that’s bad, the D-backs’ righty is actually out-performing based on his expected metrics (5.76 xERA, .300 xBA).
Los Angeles has demolished Pfaadt over a pretty substantial sample size, too.
The Dodgers are batting a collective .289 against the righty in 104 plate appearances with a .322 xBA and .635 xSLG.
Key stat: Betts has reached base in 9-of-19 at-bats vs. Pfaadt (.473 OBP) and has hit two home runs against him this year.
Best MLB picks
Sugano over 3.5 strikeouts (-115): Sugano is having a dreadful first MLB season after coming over from Japan, but he’s finally begun to turn things around.
Over his last six starts, the three-time NBP Central League MVP has a 2.62 ERA and is 4-2 against this line.
Sugano most recently fanned six Boston Red Sox and now gets to pitch against the San Francisco Giants, who have been one of MLB’s worst teams since the trade deadline.
San Fran has the sixth-highest K rate over the last 30 days. If Sugano works five-plus innings, as he’s done in six straight, this should be a breeze.
Langford over 1.5 bases (-117): A lot is working in Langford’s favour during today’s matchup against the Athletics.
- Langford is 5-for-7 against Athletics starter J.T. Ginn.
- Ginn has a 7.17 ERA this month and a 6.48 ERA at home.
- Sutter Health Park, the A’s temporary home venue, is the second-most hitter-friendly park in MLB, according to Baseball Savant’s park factors.
Langford is also on a heater this month, batting .297 with a .972 OPS. All signs point to another big night for the sophomore outfielder.
