Underdog Fantasy MLB Player Props September 12
Mike Trout OVER 1.5 Total Bases
How can we not look at Trout right now? He’s homered in six straight contests, and he has a 1.000 SLG in the month of September! Trout gets to face the left-handed Konnor Pilkington tonight, and in 2022 against southpaws, Trout has a 1.089 OPS with a 457 wOBA and 205 wRC+. Trout may not extend his streak to seven straight games with a home run, but at the very least, I do like a seventh straight game with more than 1.5 total bases.
Jose Altuve OVER 1.5 Total Bases
Altuve is 6-for-19 with two home runs in his career against Eduardo Rodriguez, and the Detroit southpaw has allowed a 6.55 ERA over his last two starts, not to mention a 4.09 HR/9. When looking at the home runs, tell me if you can spot a trend: Julio Rodríguez, Ty France, Mike Trout, Mike Ford, and Jo Adell. Four of those five players are right-handed hitters! In struts Altuve, hitting .346 with a .615 SLG over his last 13 games, and has destroyed southpaws this season to the tune of a .333 average and 1.097 OPS. On top of that, Rodriguez is a southpaw, yes, but once that Altuve has a good track record against! Give me the over!
Other Leans:
- Spencer Strider OVER 7.5 Strikeouts (14.2 K/9 over last 4 starts & SFG has 3rd-highest K% vs. RHP over last two weeks)

Player News
Nationals placed INF Luis García Jr. on the Paternity List.
García figures to miss the next three days. Amed Rosario will probably get at least a couple of starts in his place against the Braves.
Nationals recalled INF/OF Trey Lipscomb from Triple-A Rochester.
Lipscomb was up briefly last month and went 2-for-4. The 25-year-old is being groomed as a utility player by the Nationals; he’s started at least four games at first, second, third and in left field while hitting .283/.362/.380 in Triple-A this season.
Paul Skenes has announced that he will pitch for Team USA at the World Baseball Classic
Skenes has pitched for Team USA in two other tournaments during his career and actually spent two years at the Air Force Academy. He is arguably the best pitcher in baseball right now and will partner with arguably the best hitter in baseball right now, Aaron Judge, to lead Team USA in what figures to be an extremely competitive WBC tournament in 2026.
White Sox LHP prospect Hagen Smith (fatigue) will have his workload managed at Double-A Birmingham.
Hagen Smith’s velocity fluctuated in his last outing, and the White Sox were cautious about him showing some signs of fatigue. They shortened his last outing and will skip his next start to help him manage his workload in his first full professional season. Everything is fine with Smith from a medical perspective, but this is a good reminder that Smith is an immense talent, but fantasy managers shouldn’t expect a major impact this season as he adjusts to professional baseball.
Paul Blackburn (knee) will make his final rehab start for Triple-A Syracuse on Friday
Blackburn has already made four rehab starts, so he will need to be reinstated from the injured list after his start on Friday. As of now, there is no room in the Mets’ rotation, so the most likely outcome is that Blackburn would serve as a multi-inning reliever, which could bump Dedniel Nunez back to the minors.
Red Sox manager Alex Cora admitted the team will “take a look at” whether or not to remove Tanner Houck from the starting rotation.
After his brutal start on Monday, Houck admitted this is “probably the most lost [he’s] ever been.” The struggles really began in the second half of last season, but Houck now has an 8.04 ERA and has allowed double-digit runs in less than three innings twice this season already. Houck does have minor league options remaining, so the Red Sox could simply send him to Triple-A and give him time to figure out what’s going out. If they were to do so, that would allow Hunter Dobbins to stay in the rotation even after Walker Buehler returns next week.
