Pittsburgh Pirates left-handed reliever Mason Montgomery's fantasy stock is on the rise, and he is the clear favorite for saves of late after shutting the door yet again in Thursday's 5-2 win over the San Francisco Giants at PNC Park. Montgomery threw a clean ninth inning with one strikeout to pick up his eighth save of the year. Right-hander Luke Weaver worked the eighth frame for his 18th hold of the season. It looked like Weaver might take over the closing duties in the Steel City over lefty Gregory Soto when the Bucs acquired him in a deadline deal with the New York Mets, but it has been Montgomery who has been the preferred ninth-inning choice. The 26-year-old southpaw has converted eight straight save chances while giving up two runs in his last 26 innings pitched to lower his ERA for the year to 2.97. He also has a 1.06 WHIP with 90 strikeouts and 22 walks over his 57 2/3 total innings in 2026. The hard-throwing lefty should see his ownership continue to climb with the fantasy postseason approach. Right now, Montgomery is rostered in just 34% of Yahoo leagues.

After missing the previous three games with an elbow injury, Boston Red Sox catcher Adley Rutschman broke a recent slump and returned with a bang on Thursday to help beat his former team, the Baltimore Orioles, by a score of 6-5 at Camden Yards. Rutschman went 2-for-4 at the plate with two solo home runs and three RBI on the night to raise his season average to .240 and his OPS to .741. It was a much-needed turnaround for a player who has never really been able to hit his stride in 2026 due to injuries. The 28-year-old switch-hitter and former first overall pick in 2019 from Oregon State came into Thursday's series opener against Baltimore with a weak .237/.318/.400 slash line with a .718 OPS, only nine home runs, 51 RBI, and 35 runs scored in 300 at-bats. The three-time All-Star had been even worse in 15 games since being traded to the BoSox, going 9-for-59 (.170) with a homer, six walks, and 15 strikeouts. The Red Sox gave up a lot to secure Rutschman as their catcher of the future, and they are hoping his bat begins to heat up as they push to make the postseason.

Minnesota Twins infielder Brooks Lee is suddenly up to a career-high 22 home runs entering play on Thursday after homering again in Wednesday's 7-4 loss to the Athletics. In his last 11 games, the switch-hitting infielder has hit .319 (15-for-47) with a .930 OPS, four home runs, two doubles, 10 RBI, and eight runs scored to boost his overall 2026 slash line to .250/.299/.435 with a .734 OPS, 77 RBI, 62 runs scored, and seven stolen bases in his second full season in the big leagues. The 25-year-old former eighth overall pick from Cal Poly in 2022 has been much better as a lefty against right-handed pitchers, going 91-for-345 (.264) with 19 of his 22 homers, as opposed to a .218 average (34-for-156) with just three long balls as a right-handed hitter against southpaws. With eligibility at second base, third base, and shortstop, Lee is also valuable for his infield versatility in fantasy baseball, and he's available in 40% of Yahoo leagues with the playoffs approaching quickly.

Miami Marlins first baseman/outfielder Griffin Conine is not flashy by any means, but he could help fantasy managers down the stretch in September as a left-handed-hitting outfielder against right-handed pitching in the right matchups in deeper leagues. Going into Thursday's game against the Kansas City Royals, Conine entered play with a career-high 14 home runs and 32 RBI in 72 games (238 plate appearances) while hitting .254/.357/.488 with an .845 OPS. Conine has limited overall fantasy appeal because of his struggles against southpaws -- he is hitting only .178 (8-for-45) in limited exposure against lefties. He was nothing special in August, either, going 18-for-80 (.225) in 26 games, although he did have five home runs and 11 RBI after hitting six homers in 25 games in July. The 29-year-old former second-rounder by the Toronto Blue Jays in 2018 out of Duke also still strikes out a third of the time, although he is sporting a career-high 12.2% walk rate in 2026. At best, Conine is worth a look off the waiver wire in deeper fantasy leagues to close out the season. He is rostered in under 10% of Yahoo leagues.
