Philadelphia Phillies infielder Luis Arraez (ankle) suffered a sprained left ankle in Thursday's game against the Milwaukee Brewers, and the Phillies say that he will be evaluated further, according to Lochlahn March of The Philadelphia Inquirer. Arraez tried to avoid being tagged on a ground ball in the sixth inning at Citizens Bank Park and should now be considered day-to-day until we have more details. Before leaving, Arraez went 0-for-3 at the plate. Bryson Stott moved from third base to second, with Edmundo Sosa entering the contest to take over at the hot corner in Philly. If Arraez misses time going into the final weekend of the regular season, Sosa would likely continue to start at third for the Phillies, with Stott sticking at the keystone. The 29-year-old Arraez came into Thursday's action hitting .283/.314/.376 with two homers and 21 RBI in 45 games since the Phils acquired him in a deadline deal with the San Francisco Giants. The four-time All-Star and three-time batting champion would be a big loss for the Phillies if they advance to the postseason and he cannot make it back for the start of the wild-card series next week. Overall, Arraez came into Thursday with a league-high .312 batting average, looking to win his fourth batting title.

Houston Astros shortstop Jeremy Pena (wrist) is starting at shortstop and batting leadoff for the Astros on Thursday night against the division-rival Athletics and right-hander Mason Barnett, according to MLB.com. Pena was hit by a pitch on his wrist on Tuesday against the A's and was held out as a result on Wednesday, but he is back in action for the series finale in Sacramento as the Astros try to keep pace with the Texas Rangers for the lead in the American League West division. It is great news for Houston as they look to punch their ticket to the postseason in the final week of the 2026 regular season. It would be an understatement to say that Pena has been banged up with injuries this year, but he has done well at the plate when he has been available for the 'Stros, slashing .275/.325/.469 with a .795 OPS, 20 home runs, 51 RBI, 77 runs scored, and 11 stolen bases across his 426 at-bats. Pena has gotten hot lately, too, hitting .367 with three home runs in his last 30 at-bats.

Atlanta Braves star outfielder Ronald Acuna Jr. (shin) is starting in right field and is batting second against the visiting Cincinnati Reds and right-hander Brady Singer on Thursday, per MLB.com. Acuna fouled a ball off his left shin in Tuesday's game against the Reds and did not start on Wednesday, but he is back for the series finale and should be returned to all starting fantasy lineups against Singer. In just five career at-bats against Singer, Acuna is hitting .600 with a solo home run. The 28-year-old former MVP and five-time All-Star had two separate stints on the injured list this year with hamstring injuries, which have limited his overall production for fantasy managers. Acuna has hit .259 (102-for-394) with 20 home runs, 55 RBI, 20 stolen bases, and 60 runs scored. Braves fans can breathe a sigh of relief that they did not lose Acuna just before the start of the playoffs next week, and they will be hoping he can carry over his hot hitting in September. In 19 games during the month, he has gone 25-for-74 (.338) with seven homers and 19 RBI in 81 plate appearances.

Philadelphia Phillies left-hander Jesus Luzardo (shoulder) threw a bullpen session that consisted of around 30 pitches on Thursday, as expected, according to Matt Gelb of The Athletic. Luzardo said the session went well. The Phillies could look to have Luzardo throw a simulated game this weekend to face live hitters, and he remains very much in play to return to the starting rotation for the start of the postseason next week in the wild-card series. The Phillies must first get into the postseason, as they entered Thursday tied with the Chicago Cubs for the final wild-card spot in the National League, with the Arizona Diamondbacks on their tails at three games behind with four left to play. Luzardo will be eligible to come off the 15-day injured list for the regular-season finale on Sunday, but he almost certainly won't be an option to pitch in that game as the Phillies look to save him for the playoffs. Getting the 28-year-old southpaw back for next week is the team's top priority after he went 14-5 with a career-best 2.87 ERA, 1.08 WHIP, and 221:52 K:BB in 178 2/3 innings across 29 starts in his second year with the organization.
