Houston Astros second baseman/outfielder Jose Altuve (foot) is starting at second base and batting fifth on Friday for the series opener at Daikin Park against the division-rival Seattle Mariners and right-hander George Kirby, per MLB.com. Altuve fouled a ball off his left foot on Tuesday against the San Francisco Giants and was held out of the series finale on Wednesday as a result. Tests came back negative, though, and Altuve is back in action on Friday after a scheduled day off on Thursday. The 36-year-old Venezuelan veteran and nine-time All-Star will return to face a pitcher that he is pretty familiar with. Altuve has faced Kirby 24 times in his career and is hitting .208 against him with a .488 OPS and just one RBI. Fantasy managers are hoping he can continue his strong month of August in which he has gone 11-for-34 (.324) with an .841 OPS, a homer, a double, five RBI, and five runs scored in only 10 games played. Overall, the former MVP has shown his age in 2026, slashing a mediocre .240/.304/.391 with 13 homers, 35 RBI, 54 runs, and only two steals in 96 total games played in his 16th year in the majors.

According to Jim Bowden of The Athletic, the St. Louis Cardinals are promoting top outfield prospect Joshua Baez to the major leagues. Baez has enjoyed a dominant showing at the Triple-A level and is finally being rewarded with a promotion to The Show. Baez has spent the entire 2026 season at the Triple-A level, where he has flashed elite power and speed upside. Across 103 games with the Memphis Redbirds, the No. 44-ranked prospect in the sport (per MLB.com) has held a .256/.328/.573 line with 22 doubles, 34 home runs, and 21 stolen bases. Last summer, Baez hit just 20 home runs but swiped 54 bags over 117 games shared between High-A and Double-A. While his hefty 29.6% K% could translate to some going pains in the majors, his five-category profile makes him a top waiver wire target across all formats ahead of his debut.

Chicago Cubs right-hander Edward Cabrera (hamstring) will be activated from the 15-day injured list to start on Sunday against the division-rival St. Louis Cardinals at Wrigley Field, manager Craig Counsell told Patrick Mooney of The Athletic. Cabrera will return to Chicago's rotation for the first time since suffering a strained hamstring in late June. Although he struck out 15 and walked just one batter in his nine innings over three minor-league rehab starts, fantasy managers have every right to be hesitant to trust the 28-year-old Dominican hurler now that he's on the verge of returning to the big leagues. Cabrera has been inconsistent in 2026 in his first year with the Cubbies, going 5-4 with a 5.10 ERA (5.04 FIP) and 1.39 WHIP with 65 strikeouts and 29 walks in 72 1/3 frames over his 14 starts. He only threw 65 pitches in his last rehab outing, too, so we'd recommend avoiding him in his first start back this Sunday versus St. Louis. With Cabrera returning, left-hander David Peterson is now a candidate to shift back to the bullpen.

Pittsburgh Pirates outfielder Oneil Cruz (hand) is expected to continue his minor-league rehab assignment with Double-A Altoona on Friday night, according to Colin Beazley of the Pittsburgh Post-Gazette. Cruz will not be joining the Pirates for their series opener against the Boston Red Sox. It's unclear if the Pirates will consider activating Cruz from the 60-day injured list for the remainder of the weekend series against the BoSox. Through four rehab games so far at Altoona and Triple-A Indianapolis, the left-handed slugger has gone 2-for-13 at the plate with six strikeouts and three walks. He probably won't return to the big-league roster until he plays in back-to-back games in center field, so fantasy managers should probably not expect him back in Pittsburgh until at least early next week. The five-category contributor has been sidelined since the middle of June with a fractured hand, but he should remain stashed in all fantasy baseball leagues with the potential to be a difference-maker in the final month of the regular season. The 27-year-old Dominican was hitting .264/.350/.472 with an .822 OPS, 14 homers, 44 RBI, 21 stolen bases, and 45 runs in 250 at-bats before his hand injury in 2026.
