The Boston Red Sox are promoting outfield prospect Justin Gonzales to Double-A Portland, an MLB source told Ari Alexander of 7 News. Gonzales gets the call to Portland after hitting .271 with 17 home runs, 58 RBI, 11 stolen bases, and 68 runs scored in 89 games across 350 at-bats at High-A Greenville this year. The 6-foot-5, 210-pounder is ranked as Boston's No. 2 prospect at MLB Pipeline, behind only shortstop prospect Franklin Arias. The 19-year-old Dominican bats from the right side of the plate and has some of the most raw power out of any of the team's position-player prospects. Gonzales generates tons of bat speed, which in turn lights up his exit velocities, and he's not hitting as many ground balls in 2026. He projects for 30-plus home runs at the major-league level and is extremely athletic and agile despite his hulking size. Gonzales has average speed and will most likely settle into a corner-outfield spot or at first base long-term. At just 19 years of age, nobody should be expecting Gonzales to make his big-league debut in Boston next year.

Seattle Mariners right-hander Bryan Woo (shoulder) was pulled from Sunday's game against the division-rival Houston Astros after only 75 pitches because he was dealing with a little bit of soreness in his right shoulder, with manager Dan Wilson calling the early exit precautionary, per Shannon Drayer. Woo stayed in the contest long enough to earn his ninth win of the year, allowing two earned runs on three hits (two homers) while walking one and striking out five in six innings of work for a quality start as well. Because the Mariners don't seem too concerned about Woo's shoulder, fantasy managers should expect him to make his next start next weekend at home against the Chicago Cubs. After his quality start on Sunday evening on the road at Daikin Park in the 3-2 victory, Woo is now 9-8 in 2026 with a 4.10 ERA and 137 strikeouts in 138 1/3 innings pitched across his 24 starts. The former sixth-rounder in 2021 from Cal Poly gave up 10 earned runs in 10 innings in his final two starts in July, but he has now allowed just two earned runs in 18 innings over his last three starts against the Astros, Detroit Tigers, and New York Yankees.

The St. Louis Post-Dispatch's Derrick Goold reports that St. Louis Cardinals left-handed pitching prospect Quinn Mathews will be called up from Triple-A Memphis to start Game 1 of the team's doubleheader on Monday against the division-rival Cincinnati Reds. Right-hander Andre Pallante will get the nod for Game 2 for the Cards. Mathews, the team's No. 8 prospect per MLB Pipeline, was called up on Aug. 1 to make his major-league debut and allowed two earned runs with three walks and three strikeouts in five innings in a loss to the Toronto Blue Jays on the road. The 25-year-old southpaw and former fourth-rounder from Stanford University has gone 5-4 this year with a 3.27 ERA, 1.23 WHIP, and 120:61 K:BB in 99 innings and 21 starts for Memphis. Mathews will face a Reds squad that ranks 24th in the league in team OPS, but the young lefty could be sent right back down to Memphis following his second major-league start. In the long-term at the MLB level, Mathews projects as more of a back-end starter in St. Louis than an ace.

Kansas City Royals manager Matt Quatraro said that infielder/outfielder Maikel Garcia (hand) didn't play in a minor-league rehab game on Sunday, but if he's feeling good, there's a chance he could come off the 10-day injured list to rejoin the big-league club on Monday before their series opener at home against the Athletics. Garcia has gone 3-for-16 at the plate on his rehab assignment after joining Triple-A Omaha on Wednesday, and the 26-year-old could be on the verge of rejoining the Royals for the first time since being put on the 10-day injured list with a muscle strain in his left hand back on June 23. When he's activated, Garcia should take over as the team's starting third baseman, which will push Nick Loftin back to a utility role off the bench. Garcia has just three home runs, 30 RBI, and five stolen bases in 2026 in his fourth full season in the majors, but he did have 16 homers, 74 RBI, and 23 steals in 160 games as a first-time All-Star in 2025, and he had 83 stolen bases from 2023-25. With eligibility in Yahoo leagues at second base, third base, shortstop, and the outfield, Garcia should at least be a versatile speed threat for fantasy managers the rest of the way. He's currently rostered in 76% of Yahoo leagues.
