SP Trevor Rogers, Orioles @ Red Sox; $9,000

We’re looking to pay up for a pitcher this evening, but you can easily avoid a couple of the highest-salaried hurlers this evening. Instead, pivot over to Orioles ace Trevor Rogers. The left-hander absolutely excels since making his return to the diamond back on May 24, averaging 22.0 FPPG with a 1.43 ERA and 0.81 WHIP in 11 starts since then. While Rogers’ strikeout stuff doesn’t look the greatest, he’s doing well in pretty much every other category. With just 11 earned runs in his 11 starts, there’s a ton to like, even against a talented Red Sox lineup tonight. With the highest scoring average of any player on this slate and just three performances below the 20-point mark, I’m hammering Rogers’ name into my lineup and strongly recommend you do the same.

SS Geraldo Perdomo, Diamondbacks vs. Guardians; $4,800

The Snakes’ shortstop keeps delivering value in lineups and finds himself on a hot streak as of late. Geraldo Perdomo averages 9.0 FPPG this year as one of the most underrated hitters in the sport. He’s slashing .288/.388/.437 with an .825 OPS to match 74 runs, 79 RBI and 13 homers. Sure, Perdomo doesn’t bring a ton of long-ball power in this Diamondbacks order, but he does provide switch-hitting ability and finds himself averaging 13.2 FPPG over his last 10 contests. Tonight, he faces Gavin Williams (3.38 ERA, 1.31 WHIP, 127 SO) of the Guardians, but the righty doesn’t seem like an impossible matchup by any means. Perdomo should keep rolling in this matchup with a couple of knocks.

OF Ramon Laureano, Padres vs. Giants; $4,000

One of the better outfield options tonight may not be a star, but he’s provided plenty of upside in recent games with his new team. Ramon Laureano was traded to the Padres at the end of July and has fully hit his stride in recent games. He averages 8.1 FPPG this season, a mark which increased to 10.3 FPPG over his last 10 contests. He’s a great hitter to begin with, boasting a .298/.364/.556 slash line with 56 runs, 58 RBI and 19 homers. As of late though, Laureano posted 21, 14, 28 and 19 points across four of his last five games. The Giants’ Robbie Ray (2.98 ERA, 1.14 WHIP, 152 SO) is a tough matchup, but Laureano should be fine in this one especially once the bullpen enters.
