Seattle placed center fielder Julio Rodriguez on the 7-day concussion IL after a throw from first baseman Nolan Schanuel struck him in the back of the helmet while he was sliding into second base Thursday night. The Mariners selected infielder/outfielder Miles Mastrobuoni from Triple-A Tacoma in a corresponding move. Victor Robles — also involved in Thursday's collision — was able to return to the outfield Friday.
Milwaukee promoted 21-year-old outfield prospect Luis Lara for a doubleheader against the Cardinals, making his big-league debut. Lara posted a .321/.432/.470 line with 24 stolen bases, a 15.6% walk rate, and a 13.9% strikeout rate across 78 Triple-A games — then signed a 7-year, $31M extension before his first MLB plate appearance. Blake Perkins was optioned in the corresponding move.
Ryan Helsley landed on the 15-day IL with right elbow discomfort — the same elbow that cost him seven weeks earlier in 2026. Tyler Wells immediately stepped in and notched saves in back-to-back appearances, backed by a 0.60 WHIP and 31.9 K-BB% over his last 10 outings. Andrew Kittredge and Yennier Cano are also in the mix, but Wells has clearly taken the lead.
Ohtani was scratched from a recent lineup with left bicep soreness after exiting a game early. Manager Dave Roberts characterized the injury as limited concern, said Ohtani was feeling considerably better the following day, and indicated a return could come as soon as the next game. Ohtani had also been managing left knee inflammation earlier in July.
Who's Hot This Week
Made his MLB debut Tuesday after posting .321/.432/.470 with 24 stolen bases and a 13.9% strikeout rate in 78 Triple-A games. Milwaukee already signed him to a 7-year, $31M extension before his debut — that level of organizational commitment signals this is no short cup of coffee. His stolen-base ceiling and elite OBP profile give him immediate fantasy upside. Grab him now before ownership climbs into double digits.

Scratched from a recent lineup with left bicep soreness after exiting a game early. Manager Dave Roberts characterized the injury as limited concern, said Ohtani was feeling considerably better, and indicated a return is possible in this series. Also managing residual left knee inflammation from earlier in July.
Ian Seymour has quietly assembled one of the best three-week stretches of any starting pitcher on the waiver wire. The Tampa Bay Rays' left-hander allowed just one earned run over his last 13 innings entering the week, generating back-to-back quality starts while working through a rotation that initially kept him in a bullpen role despite 145 minor-league innings last season.
The pitch driving Seymour's breakout is his sweeper, which runs a 39.5% whiff rate — among the best for any single pitch in baseball right now. He pairs it with a changeup, sinker, and four-seamer that each play differently, and the combination allows him to generate weak contact even without overpowering stuff. His 3.33 xERA suggests his 4.02 surface number is slightly punishing him for results outside his control — the underlying process is significantly better than the top-line stat.
The Rays have an exceptional track record developing young arms just like Seymour, and the results are consistent with what that system produces: improving command (down to a 1.09 WHIP), elite whiff generation on his primary out-pitch, and a four-pitch mix that plays both sides of the plate. The main concern is his fly-ball tendency — pay attention to his home park schedule and target starts in pitcher-friendly environments.
The July 7 Leverage Ledger covered an eight-game slate with a chaotic save environment — five blown saves across the board. The headline situation: Ryan Helsley heading back to the IL with elbow discomfort for the second time this season, immediately reshuffling Baltimore's ninth inning.

Meanwhile, Pete Fairbanks continued his alarming stretch in Miami, posting his fourth straight appearance allowing at least one earned run and raising his ERA to 7.27.

|---|---|---|---|
| Tyler Wells | BAL | 🟡 Watch | Immediate successor to the injured Helsley — back-to-back saves, 0.60 WHIP over last 10 outings, 31.9 K-BB% in that stretch. Yennier Cano and Andrew Kittredge provide committee risk, but Wells has the hot hand and manager trust right now. Add in every format. |
| Pete Fairbanks | MIA | 🟡 Watch | 7.27 ERA over his last four appearances with at least one run allowed in each outing. Michael Petersen (3.08 ERA, 14 holds, 10.9 K/9) is a credible replacement and has been functioning as the primary setup man for over a month. This closer situation could flip any day — monitor before rostering. |
| Jordan Romano | COL | 🔴 Committee | Recalled July 4 and earning save opportunities for Colorado, but the Rockies' limited win total caps his ceiling. Relevant in 14-team-plus leagues only; avoid in standard formats where save volume matters. |
