MLB DFS Picks Today: Sept. 29, 2026
Redeem Underdog promo code LABSNEWS and tail my MLB DFS picks today. Since my lineup has four picks, I Flex Played it so I still win even if I miss a leg:
| Game | DFS Pick | Why I Like Him |
|---|---|---|
| Phillies vs. Braves (2 p.m. ET on NBC) | Matt Olson | Atlanta gives Olson a premium middle of the order spot. Philadelphia opens with Jesús Luzardo in a limited role after his recent return from the injured list. |
| White Sox vs. Astros (5 p.m. ET on Peacock) | Yordan Alvarez | Alvarez had a 42 homer regular season and a batting title caliber campaign. Chicago also faces a Houston lineup built around Alvarez and several established bats. |
| Red Sox vs. Yankees (8 p.m. ET on NBC and Peacock) | Ben Rice | Rice sits near the top of the Yankees lineup against Boston rookie Payton Tolle. Tolle brings major strikeout ability, but Rice offers premium lineup volume in a postseason environment. |
| Cubs vs. Padres (10 p.m. ET on Peacock) | Fernando Tatis Jr. | San Diego gets home field at Petco Park, while Michael King starts for the Padres after a 12 win, 3.21 ERA season with 159 strikeouts. Tatis supplies power and speed near the top of the San Diego attack. |
