New York Yankees relief pitcher Mark Leiter Jr. (paternity) was activated off the paternity list earlier Sunday morning. The right-hander was away from the team for a few days but should be expected to return to his high-leverage role on Sunday and during the playoffs. Since being traded to the Yankees at the trade deadline, Leiter Jr. has logged a 5.23 ERA, 1.68 WHIP, with a 7:30 BB:K ratio across 20 2/3 frames. Earlier this season with the Cubs, Leiter posted a 4.21 ERA and a 1.10 WHIP through 36 1/3 innings of work. Leiter has generated whiffs and strikeouts at a strong 37.3% and 33.2% respectively and could occasionally mix in for save opportunities during October.

Chicago White Sox outfielder Luis Robert Jr. (ribs) is returning to the starting nine in the final game of the 2024 season. Robert was kept out of the lineup for the past two games due to soreness in his rib cage. The 27-year-old will cover center field and bat in the two-hole. After hitting a career-high 38 home runs last season, the outfielder took a significant step back this summer as he has hit only 14 with a modest .224/.279/.381 slash line. He will face Detroit right-hander Kenta Maeda who enters Sunday's tilt with a hefty 5.93 ERA which makes Robert a solid play in DFS.

Boston Red Sox starting pitcher Quinn Priester was recalled ahead of his start on Sunday afternoon. Priester has spent his entire time in the Red Sox organization pitching for Triple-A and will be set to make his Boston debut on the final day of the regular season. Through 38 1/3 innings at Triple-A Worcester, the former Bucco held a 5.40 ERA, 1.25 WHIP, with a 12:42 BB:K ratio. In 44 innings at the major league level in the Steel City this summer, Priester posted a 5.04 ERA and a 1.46 WHIP. The 24-year-old has continued to show growing pains against the top level of the minor leagues and the majors and should not be considered as a streaming option this afternoon.

Colorado Rockies starting pitcher Ryan Feltner (arm) is set to start in the final game of the regular season on Sunday afternoon against the Los Angeles Dodgers. Feltner left his previous start early due to cramping but that injury does not seem serious as he will get the nod in the season finale. The Ohio State product has held a 4.66 ERA, 1.36 WHIP, with a 50:135 BB:K ratio across 156 1/3 innings of work. The right-hander has held a slightly higher 5.53 ERA and 1.49 WHIP at home, where he will pitch this afternoon against a high-powered Dodger offense. DFS players should look to avoid Feltner in this start as he will have a tall task ahead of him.

San Diego Padres starting pitcher Matt Waldron was recalled from Triple-A El Paso earlier on Sunday. In a corresponding move, the Padres demoted right-handed pitcher Randy Vasquez to the minor leagues. Vasquez was given the starting nod on Saturday evening and held his own against the Arizona Diamondbacks as he tossed six shutout innings with only one hit and one walk. Martin Perez is slated to start in the regular season finale for San Diego but Waldron could be deployed as a long relief option if Perez struggles. Fantasy managers should avoid streaming Perez this afternoon as he has generated strikeouts at a very low 18.2% rate this summer.
