Cooper Hjerpe threw four perfect innings in his major-league debut at Coors Field, retiring 12 Rockies and earning his first win as the Cardinals rallied to a 10-8 victory. The 25-year-old’s recovery from multiple elbow surgeries highlights a growing depth of left-handed pitching in St. Louis and sets up a managed workload path toward 2027 as the club continues to build its rotation.
The Minnesota Twins called up their top prospect Walker Jenkins, 21, to make his MLB debut Friday against the Chicago White Sox, aiming to bolster a fading playoff bid. Jenkins is the Twins’ highest-ranked prospect since Byron Buxton and will be their youngest position player to debut since Buxton in 2015, a move tied in part to Buxton’s hip injury.
Seattle designated left-hander Jhonathan Diaz for assignment to clear 26- and 40-man roster space for top pitching prospect Kade Anderson, who will make his MLB debut today against the Cubs as Seattle plans a six-man rotation. Diaz appeared in one MLB game this season (1 1/3 IP, one earned run) after a 2026 Triple-A Tacoma run with a 6.22 ERA over 111 1/3 innings and 20 homers allowed. Anderson’s promotion marks his arrival to the majors amid health questions surrounding teammates Bryan Woo and Bryce Miller.
Seattle Mariners promote 22-year-old left-hander Kade Anderson, the No. 3 pick in the 2025 draft, to make his MLB debut Saturday against the Cubs. He has dominated Double-A Arkansas this season with a 1.06 ERA, 0.64 WHIP and a 135/13 K/BB across 93 1/3 innings, making him a must-roster fantasy asset with immediate impact potential.
The Seattle Mariners will call up top pitching prospect Kade Anderson to make his major-league debut Saturday at home against the Chicago Cubs, aiming to spark a playoff push. Anderson, The Athletic’s No. 1 prospect, has dominated in the minors with a 1.06 ERA and 135 strikeouts in 18 starts for Double-A Arkansas this year and will need to be added to Seattle’s 40-man roster, likely via moving Matt Brash to the 60-day injured list to create space amid Seattle’s slide in the standings.
Seattle called up left-hander Kade Anderson, widely regarded as MLB's top pitching prospect, to make his big-league debut on Aug. 22 against the Cubs after a dominant run in Double-A Arkansas (93.1 IP, 135 K, 13 BB; 1.06 ERA with 1.78 FIP, 2.67 DRA). Anderson brings a varied arsenal (fastball, slider, curve, change) and is expected to anchor a rotation often stretching to five innings per start; the promotion is timed to preserve 2027 rookie eligibility via the service-time clock, and Dipoto has signaled he won’t be used in relief, though innings remain closely monitored.
Seattle will promote pitching prospect Kade Anderson to make his MLB debut against the Cubs on Saturday, creating a 40-man roster hole likely by transferring Matt Brash to the 60-day injured list due to his lat strain. Anderson, widely regarded as the top pitching prospect in the game and the third overall pick in 2025, has dominated Double-A Arkansas (18 starts, 1.06 ERA, 41% strikeouts) with a four-pitch arsenal and advanced command. His arrival could spur Seattle to a six-man rotation as they look to turn around a sputtering season; the Mariners sit 60-68 and remain in the AL West race but outside the top Wild Card spots, seeking a spark from their top prospect.
Cardinals prospect Joshua Báez, who once drove for DoorDash, erupted in his MLB debut by going 3-for-4 with three home runs and five RBIs, becoming the first player to homer in each of his first three at-bats. He previously hit 34 HR with 90 RBI and 21 stolen bases at Triple-A Memphis and could stick with the majors for the rest of the season.
The Detroit Tigers promoted Brett Callahan from Triple-A Toledo to make his MLB debut and designated Trei Cruz for assignment to clear a 40-man spot. Callahan, 24, has a strong minor-league track record (Double-A: .268/.374/.504, 133 wRC+, 29 steals) and could provide outfield depth as injuries to Carpenter, Greene, and Outman linger; he’ll remain rookie-eligible if he stays under 130 at-bats this season. Cruz, who debuted in June, has struggled to a .232/.288/.289 line with a 56 wRC+ in Toledo and was designated for assignment to preserve roster flexibility, with a real chance to return to Triple-A if he clears waivers.
Cardinals rookie Joshua Báez became the first player in MLB history to homer in his first three big-league at-bats, notching three homers at Wrigley Field after leading the minor leagues with 36 homers prior to his promotion.
George Lombard Jr., 21, debuted as the Yankees’ shortstop and is the third-youngest to do so in the franchise’s history, signaling a bright future and the potential to be a “very special” contributor amid a lackluster deadline.
The Minnesota Twins plan to promote top shortstop prospect Kaelen Culpepper for his MLB debut during an upcoming series in Milwaukee, which will require a 40-man roster addition and likely a corresponding move off the roster. Culpepper, viewed as the club’s No. 2 prospect, has advanced quickly through the minors and posted strong numbers at Triple-A this season, bringing defensive versatility and potential immediate offensive impact as Minnesota contends for a playoff spot.
Mets pitcher Jefry Yan, 29, made his MLB debut in Cleveland on Aug. 5, 2026, striking out his first batter and celebrating with a signature jump-in-the-air and ground-smack that instantly drew attention and sparked talk about his flamboyant style in the majors.
George Lombard Jr. homered in his MLB debut with the Yankees, while his brother Jacob homered in his pro debut for the Marlins’ Low-A affiliate, marking a memorable family milestone. The piece also notes Yankees prospect development discussions around Volpe and Domínguez, potential position tweaks, and the addition of Heliot Ramos via trade.
Tarik Skubal’s Dodgers debut at Wrigley Field drew a chorus of boos and taunts from Cubs fans, but he worked six innings and allowed two runs with six strikeouts in a 5-1 defeat. The hostile atmosphere highlighted the high-profile nature of his acquisition, while LA’s offense and bullpen struggled, leaving Skubal to navigate a playoff-like reception as he begins his Dodgers tenure.
