The Houston Astros have placed infield prospect Brice Matthews (concussion) on the Triple-A 7-day injured list with a concussion. According to Chandler Rome, Matthews sustained this injury after a slide. Fantasy managers should continue to monitor his status as he slowly ramps up his activity. Through the first 37 contests of the Triple-A regular season, Matthews has posted a .234/.375/.375 slash line with two doubles, two triples, and four home runs. Matthews has tallied 23 runs, added 13 RBI, and swiped 16 bags. He was riding a three-game hitting streak prior to the injury. If he is able to return to form, the former 28th overall pick should be in the mix to make his MLB debut in the second half of the campaign. For now, he should not be stashed in any redraft leagues.

The Tampa Bay Rays announced on Friday that they reinstated infielder Yandy Diaz from the restricted list and optioned infielder Coco Montes to Triple-A Durham in a corresponding move. Diaz was placed on the restricted list earlier this week due to a visa issue that prevented him from entering Canada and playing in the series against the Toronto Blue Jays. He's back with the team now and should be in the starting lineup for Friday's series opener in Miami against the Marlins and right-hander Max Meyer. For DFS purposes, it's not the greatest matchup for the 33-year-old Cuban veteran against a pitcher on the rise who he has never faced in his career. Diaz will be returning to a mediocre .238/.291/.400 slash line with a below-average .691 OPS, six home runs, 20 RBI, 15 runs and two steals on the year. He has three homers in 10 games in May but is hitting just .184 (7-for-38).

Cleveland Guardians outfielder Angel Martinez is sitting out of Friday's series opener against the hosting Cincinnati Reds at Great American Ball Park. Nolan Jones will start in center field and hit in the two-hole against Reds right-hander Brady Singer. This will be the second time in the last four games that Martinez finds himself starting on the bench since the team recalled outfielder Will Brennan, who is in right field and in the nine-hole on Friday. It's bad news for fantasy managers that were using the 23-year-old Dominican in their starting lineups in AL-only leagues early in the season. The switch-hitter has only gone deep once, but he's batting .295 (28-for-95) and has added 11 RBI, 11 runs and four stolen bases. He has just one hit in his last 12 at-bats, though. Jones has gone just 4-for-26 (.154) in 12 games in May, but he has hit .714 with two RBI in seven career at-bats against Singer.

Cincinnati Reds outfielder TJ Friedl (wrist) is back in center field and is hitting leadoff for Friday's series opener against the visiting Cleveland Guardians at Great American Ball Park. Friedl suffered a bone bruise in his right wrist during a fall on a collision with teammate Elly De La Cruz on Tuesday and missed the last two games as a result. But the 29-year-old is back in there on Friday and will face Guardians right-hander Tanner Bibee, who he has hit .400 against with a .900 OPS in a small sample size of five career at-bats. He doesn't have a ton of power but has been a steady contributor as Cincy's starting center fielder in 2025, slashing .274/.359/.382 with three long balls, 17 RBI, 23 runs scored and eight stolen bases. Friedl is most useful for his runs and speed in deep-mixed leagues. He's hit .270 (10-for-37) in 12 games in May with two homers, five RBI and three steals.

The Chicago White Sox do not expect outfielder Mike Tauchman (hamstring) to come off the 10-day injured list to rejoin the team this weekend during their three-game series at Wrigley Field against his former team, the Chicago White Sox, according to the Daily Herald's Mike McGraw. The White Sox are going to give him more time to ramp up after his second right-hamstring strain of the season. The 34-year-old veteran isn't going to be rushed back, but it's possible that he'll be back at some point next week after already playing in four minor-league rehab games. When he's healthy, Tauchman will have value in AL-only affairs as the team's likely starting right fielder against right-handed pitching. Before his second hammy injury, Tauchman had gone 4-for-10 in a small sample size in 2025 with a run scored in three games.
