Today’s MLB DFS & Player Props Picks

Tuesday’s Starting Pitcher Rankings

Logan Webb (SF) at CHC
Logan Webb has chewed up innings and pitched well lately. According to FanGraphs, in his previous five starts spanning 33.0 innings, Webb has had a 3.00 ERA, 2.58 xFIP, 2.84 SIERA, 0.94 WHIP, 52.2 GB%, 2.4 BB%, 24.6 K%, 30.0 CSW%, 117 Stuff+, 110 Locaton+ and 113 Pitching+. He's spun six quality starts in his past seven opportunities and pitched at least 6.0 innings in all seven games. Webb has also been unphased by pitching on the road, twirling three straight quality starts in road contests.

He has a decent matchup tonight. This season, the Cubs are tied for 19th in wRC+ (94) with a 24.0 K% versus righties and tied for 16th in wRC+ (99) with a 23.6 K% at home. Chicago was also 22nd in wRC+ (91) with a 22.5 K% in the last 14 days. The Giants are -110, but the game's total is a somewhat concerning 9.5 runs. Still, Webb doesn't beat himself with walks, and his high groundball rate can help him if the winds gust out tonight.

Alec Marsh (KC) at OAK
Alec Marsh was unlucky lately. In his past five starts spanning 30.0 innings, Marsh had a 5.10 ERA, 3.95 xFIP, 3.74 SIERA, 1.13 WHIP, 7.4 BB%, 24.8 K%, 26.3 CSW%, 102 Stuff+, 99 Location+ and 97 Pitching+. His ERA estimators weren't outstanding but were markedly better than his ERA. Thus, Marsh's salary is too low at both DFS outlets.

He can get right tonight against the Athletics. Oakland is tied for 22nd in wRC+ (93) with a 26.8 K% versus righties and 14th in wRC+ (103) with a 24.3 K% at home this year. The A's were also 28th in wRC+ (71) with a 27.4 K% in the previous 14 days. Thus, the Royals are -135, and the game's total is 8.0 runs.

Spencer Schwellenbach (ATL) vs. DET

Spencer Schwellenbach has a putrid 6.32 ERA through his first three starts, totaling 15.2 innings. Yet, the rookie's 3.86 xERA is more palatable, and his plate discipline and pitch-modeling data are encouraging. Schwellenbach has a 28.4 CSW%, 99 Stuff+, 107 Location+ and 105 Pitching+. Schwellenbach was fine in his first start, allowing three runs on five hits, one walk and five strikeouts in five innings. However, he had his best start in his most recent chance, holding the Orioles to two runs on four hits, two walks and three strikeouts in six innings.

Schwellenbach can build on his first quality start in a favorable matchup. In 2024, the Tigers are tied for 19th in wRC+ (94) with a 24.3 K% versus righties and tied for 21st in wRC+ (89) with a 24.9 K% on the road. In the last 14 days, they were 27th in wRC+ (81) with a 23.9 K%. The betting info is mixed. The good news is that the Braves are -170. The bad news is that the game's total is a hitter-friendly 9.5 runs. Nevertheless, Schwellenbach's bargain salary makes it easy to stomach the blemishes.

Suggested Lineup Stacks

• Road (Coors Field)
• Game Total/Moneyline: 12.0 Runs/LAD -185

The Dodgers are in an eruption spot, even with Mookie Betts on the Injured List (IL). Los Angeles is first in wRC+ (129) versus lefties and tied for first in wRC+ (119) on the road. They're not in just any road environment, either. Instead, they're in MLB's most hitter-friendly ballpark, facing a below-average lefty. In Austin Gomber's last four starts, he's had a 7.58 ERA, 4.33 xFIP, 4.52 SIERA and coughed up 1.89 HR/9. In addition, Gomber has allowed a .334 wOBA to lefties and a .329 wOBA to righties this year, putting all LA's hitters in play as stacking options.

• Home (Truist Park)
• Game Total/Moneyline: 9.5 Runs/ATL -170

Casey Mize has been a raging dumpster fire lately. In his last five starts lasting 21.1 innings, he's had a 6.33 ERA, 5.18 xFIP, 5.46 SIERA, 2.02 WHIP, 8.7 BB%, 10.7 K%, 5.0 SwStr% and 25.9 CSW%. He can't miss bats, and opponents are punishing him for it. Among Atlanta's projected starters, six have had at least a 102 wRC+ against righties since 2022, with four tallying at least a 116 wRC+.

Core Studs

• In 326 plate appearances against lefties since 2022, Teoscar Hernandez has hit 23 home runs with a .313 OBP, .298 ISO and 146 wRC+.
• Will Smith has mashed 16 taters with a .390 OBP, .234 ISO and 152 wRC+ in 359 plate appearances against southpaws since 2022.
• Matt Olson is white-hot. In 136 plate appearances since May 13, he's had a .368 OBP, .256 ISO and 163 wRC+.

Value Plays/Punts

• In Jarred Kelenic's past 76 plate appearances, he's had a .329 OBP, .254 ISO and 142 wRC+, with four homers and two stolen bases. He is also amid a three-game hitting streak since moving to the leadoff spot on June 15.
• Paul DeJong has hit 14 homers with a .289 OBP, .240 ISO and 115 wRC+ in 239 plate appearances this year and hits cleanup for the White Sox. He's a fine pick at FD but a screaming value at DK.
• Josh Lowe isn't especially appealing at DK. Yet, he's a steal at FD. In 337 career plate appearances against righties on the road, he's hit 18 homers with a .347 OBP, .251 ISO and 142 wRC+.
