Week 8 is shaping up to be one of the more interesting waiver periods of the young 2026 season. Injuries are reshuffling rosters across the league, and opportunity is knocking for several players who may still be sitting unowned in your league. Whether you are chasing stolen bases, power, or pitching strikeouts, there is something worth targeting right now. Let's get into the names you should be adding before your leaguemates beat you to the punch.
This is the most urgent add of the week. PlayCaller's beat reporter signal flagged Fernandez as a role expansion candidate after Nolan Arenado was lifted from Tuesday's game with right groin tightness. Arizona has a team off day Thursday, which means Arenado will miss at minimum two games, and groin injuries at Arenado's age have a habit of lingering longer than initially announced. Fernandez steps directly into the starting lineup at third base and should be owned in all formats while this situation plays out. Grab him immediately.
If you already own Arenado, do not panic drop him. The injury is being classified as tightness rather than a strain, and the built-in off day Thursday helps Arizona manage his recovery without a lengthy IL stint. Monitor his status closely heading into the weekend series, but the expectation from the club is a short absence. Arenado's power and run production make him worth holding through this brief window.
Smith is worth a stash in deeper leagues right now. He started a rehab assignment in the Arizona Complex League on Monday following elbow surgery and is progressing toward a return to the major league roster. Once activated, he is expected to compete for starts against right-handed pitching at first base and designated hitter. Arizona's lineup has the depth of run support to make Smith a contributor, and getting ahead of his activation puts you in a strong position.
Puk tossed a perfect inning with a strikeout in his Arizona Complex League rehab appearance and is advancing up the affiliate ladder before rejoining Arizona's bullpen. He carries high-leverage upside and has the stuff to pitch in late-inning situations. Bullpen roles can shift quickly, so stashing Puk now in leagues that reward holds and strikeout rate gives you a potential weapon heading into the second half of May.
Look at the two-start pitchers available in your league this week and prioritize arms facing bottom-third offenses in both matchups. Strikeout rate and walk rate over the last three weeks are the cleaner predictors of performance than ERA at this point in the season, so focus on pitchers with a strikeout-to-walk ratio above 3.0 who are available in your format.
With lineups across the league shifting due to early-season injuries, outfield streamers are valuable right now. Target players in strong lineup spots who are seeing consistent at-bats against opposing southpaws and posting hard-hit rates above 40 percent. Production in favorable platoon matchups is one of the more reliable short-term fantasy signals in May.
