Free MLB player props, odds for August 7: Use Luis Robert and Eury Perez in Thursday MLB props

Luis Robert Jr.'s .662 OPS might not be what the White Sox had hoped for this season, but the 28-year-old center fielder has had a dynamic season on the basepaths. Robert enters Thursday with 30 stolen bases, and the White Sox will take on the Mariners in one of only four games on the MLB schedule today. Robert's listed for as high as +320 at Caesars to steal a base, and that's one of our top MLB player props on Thursday.

Luis Robert Jr., White Sox, over 0.5 stolen bases (+330)

Robert hit his 12th homer of the season on Tuesday and then stole his 30th base of the season on Wednesday in this series, and he's generally playing better in the second half of the season. Since the MLB All-Star break, Robert is hitting .383 and has stolen seven bases in 13 games. Mariners starter Logan Gilbert has a decent move and generally holds runners solidly, but baserunners are 43 of 52 on stolen base attempts in his career. 

Eury Perez, Marlins, under 5.5 strikeouts (-105)

Perez has a 2.70 ERA on the season, but the Marlins have been cautious with their young ace after he underwent Tommy John surgery last April. He's only pitched 50 innings in 10 starts, and he's only lasted six innings or longer in three of those outings. He's had five strikeouts or fewer in two of his last three starts, and the model sees some value to the under here. This prop is available at DraftKings, and with the updated DraftKings promo code, new users can get $200 in bonus bets instantly as well as over $200 off NFL Sunday Ticket: 

Kyle Stowers, Marlins, over 0.5 home runs (+400)

Stowers only had six home runs in 313 career big league at-bats entering this season but he's been a revelation in 2025. He's belted 25 homers this season and has a .935 OPS. The batted-ball data bears that success out too, as he's 98th percentile among MLB hitters in barrel rate (18.9%), 96th percentile in expected slugging (.554), 91st percentile in hard-hit contact rate (52.0%) and 90th percentile in bat speed (75.0 mph). This prop is available at BetMGM, and the latest BetMGM promo code gets new users up to $1,500 in bonus bets back if your first bet loses:

MLB HR, stolen base, strikeouts prop cheat sheet

The SportsLine Model was developed and is powered by the Inside the Lines team. You can find all of the team's picks and content at our blog, which has all our personal best bets for free. The system is simple. We take the strongest SportsLine Model projected values vs the best available prices at the time we publish our content. In most cases, lines move in 'our direction' so you should bookmark the blog, follow us on social, and make it a habit of checking for updates throughout the day to maximize your expected value. 

The table below shows today's projected leading Home Run, Stolen Base and Strikeout Leaders. We include the projection and for HRs and SBs the money line we'd set for YES HR/SB. You can use this cheat sheet to compare it to your book's line and if your book's line is significantly higher than ours (and you like the player) then you would want to consider that bet. 

Yesterday, we successfully spotlighted Tyler Soderstrom for getting priced at +575 to hit a HR which was 100+ ML units higher than he was getting before his 9 game HR-less streak. Well he rewarded us with an early HR last night. I don't know if you'd want to press your luck but the markets now definitely do not see him going yard again with his best priced Yes HR line up to +600 on Fanatics. 

It is a light slate on Thursday with just 4 games so there are only 6 HR hitters and 4 SB lines under +400. The biggest name on the mound is Paul Skenes but our projection of 6.8 Ks is right in line with u7.5 at -130 on DraftKings. Eury Perez is interesting. DraftKings is offering under 5.5 at +100. He has gone over 5.5 in his last 3 road games, but overall he has averaged just 4.7 Ks on the road (vs 5.8 at home).
