Irvin starts for Washington in a key spot, needing length and quality against a Rays lineup capable of exploiting mistakes. A strong effort could stabilize WAS’s rotation down the stretch and influence fantasy streaming decisions.

Irvin’s 8-8 record is tempered by a 5.30 ERA and 1.40 WHIP; road numbers show more HR/9 and a tendency to yield against Nationals opponents, making him the focal point of a favorable Suarez matchup and NL East betting angles.

Irvin carries a high ERA and hard-hit indicators in a tough matchup versus Philadelphia, especially with a weak Nationals bullpen behind him. His command and contact metrics suggest the Phillies have a path to multiple runs, elevating the risk for Nationals’ side in DFS and bets.

Irvin carries a high-usage four-seamer profile that Lindor and Stott can exploit. Against a Phillies lineup, consider Phillies stacks with targeted exposure but monitor his early-innings velocity and control.

Irvin has ridden a rollercoaster season, closing games with 27 homers allowed in 25 appearances and a 5.14 ERA. August has been rough (9.45 ERA), and the Nationals’ wild-card relevance is minimal, making his spot in a series opener a pivotal test against a Mets lineup that has Lindor on a hot streak.
