Best MLB prop bets June 15: Back Fernando Tatis Jr. and Mookie Betts to score on Sunday

MLB prop bets

Fernando Tatis Jr. headlines Sunday’s superstar-laden MLB prop bet recommendations.

Today’s MLB props narrative: Tatis’ San Diego Padres are on the verge of getting swept by the Arizona Diamondbacks, but the star right fielder has been getting aboard at a solid clip and has value to score.

Check out the best MLB prop bets for June 14, also featuring Mookie Betts and Bobby Witt Jr.

Best bet: Tatis to score (-125)

My colleague Jordan Horrobin recommended this play yesterday, and it cashed as Tatis went 2-for-5 and scored two runs.

I’ll go back to that well on Sunday for a few reasons.

  • Tatis has scored six runs in his last five games while slashing .375/.545/.438.
  • He has a stellar .396 on-base percentage in June, scoring 10 runs and going 7-5 vs. this line.
  • The outfielder has a great history against D-backs starter Merrill Kelly, reaching base safely in 11-of-28 plate appearances (.392 OBP) with four home runs.

Kelly has struck out Tatis at an absurd 32.1% clip in those matchups, which is a drawback. However, Tatis is sporting the lowest K rate of his career (18.1%), by a wide margin, with his second-highest walk rate (10.6%).

Arizona’s righty has logged consecutive scoreless outings, but has a 34th percentile xBA (.260) and a 10th percentile hard-hit rate.

Batting leadoff on the road, Tatis should have plenty of chances to get aboard.

Key stat: Tatis is 4-1 against this line in his last five games.

Best MLB picks

Betts to score (-118): Getting Betts to score at this price is very compelling.

The MVP shortstop has been getting aboard at a stellar .429 clip this month and bats ahead of big names like Will Smith, Freddie Freeman, and Teoscar Hernandez.

Tonight, the Los Angeles Dodgers face off against the San Francisco Giants and Kyle Harrison.

The 23-year-old arm is largely unproven and ranks in the 30th percentile or lower in xERA (4.58), xBA (.264), barrel rate (10.6%) and hard-hit rate (48.5%).

I think the Dodgers can demolish the young lefty on Sunday Night Baseball.

Witt over 1.5 bases (-143): Let’s get the ugly out of the way: Witt is hitless in his last four games.

The good news is a player like Witt won’t be held down for long, and today he has an A-plus matchup against Jeffery Springs of the Athletics.

The southpaw has a 4.64 ERA and his 4.08 xERA isn’t much better. In his last three starts, Springs has allowed 16 hits and 12 earned runs in 14.2 IP.

Witt is slashing .308/.373/.462 vs. LHP this year.
