Tuesday’s Best MLB Underdog Fantasy Player Predictions
Mark Vientos HIGHER 7.0 Fantasy Points
Mark Vientos is a handful for lefties. According to FanGraphs, in 230 career plate appearances against southpaws, Vientos has had a .317 OBP, .218 ISO and 126 wRC+. He’s also having a full-blown breakout at the dish. In 100 games and 406 plate appearances this year, Vientos has hit 24 homers with 52 runs, 62 RBIs, a .328 OBP, .251 ISO, 137 wRC+, .361 wOBA and .341 xwOBA.
Vientos has a favorable matchup tonight. Mitchell Parker has struggled mightily on the road. The lefty has surrendered a .348 wOBA to 200 right-handed batters on the road this season.
Pete Alonso HIGHER 7.0 Fantasy Points
Parker’s road struggles have extended beyond getting hammered by righties. In 59.0 innings on the road, Parker has had a 6.25 ERA, 4.40 xFIP and 1.61 WHIP. So, Vientos and Pete Alonso should have run-scoring opportunities.
Alonso is also equipped to take advantage of the matchup. In 515 plate appearances against lefties since 2022, Alonso has hit 31 homers with a .344 OBP, .265 ISO and 131 wRC+.

Ian Happ HIGHER 7.0 Fantasy Points
Ian Happ doesn’t make life easy for righties. In 1,474 plate appearances against right-handed pitching since 2022, Happ has had a .358 OBP, .191 ISO and 126 wRC+. He’s also in rock-solid form. In Happ’s last 26 games and 121 plate appearances, he’s hit one homer and stolen four bases with 14 runs, 14 RBIs, a .364 OBP, .119 ISO and 122 wRC+.
Meanwhile, Happ has a favorable matchup. Mitch Spence has struggled on the road. The rookie righty has had a 4.82 ERA and 4.54 xFIP in 65.1 innings on the road. Furthermore, Spence has yielded a .375 wOBA to 123 lefties on the road this season.
Dansby Swanson HIGHER 7.0 Fantasy Points
Dansby Swanson’s matchup is also favorable against Spence. Oakland’s starting pitcher has allowed a .324 wOBA to 156 righties on the road this year. Swanson is approximately an average hitter against righties, which is good enough against Spence.
Yet, Swanson’s recent heater is the primary reason for selecting this prop. In Swanson’s previous 26 games and 113 plate appearances, he’s hit six homers and stolen seven bases with 28 runs, 21 RBIs, a .345 OBP, .230 ISO and 135 wRC+.
