Diamondbacks claim Jesús Sánchez off waivers from Blue Jays

What happened

Both the Diamondbacks and Blue Jays announced the waiver claim of outfielder Jesús Sánchez by Arizona, as reported by Darragh McDonald at MLB Trade Rumors. Toronto had designated Sánchez for assignment last week, and Arizona moved to claim him after opening a 40-man spot when the club designated Lourdes Gurriel Jr. for assignment in recent days. Because Sánchez is out of options, he cannot be sent to the minors — once he reports to Arizona, he will need a spot on the active roster.

The timing carries a significant caveat: because Sánchez is joining the organization after the September 1 cutoff, he would not be eligible to play for Arizona in the postseason if the club qualifies, per the report.

Why it matters

The Diamondbacks are sitting at 79-71 (.527), ranked 4th in the Wild Card picture and 2.5 games relative to the cut line, on a two-game losing streak. With roughly two weeks remaining in the regular season, the club is not in a position to be patient with roster construction. Per the report, Arizona is hoping to catch lightning in a bottle for just that brief window — a characterization that doubles as an honest accounting of the situation.

The move is also a direct operational consequence of the Gurriel Jr. designation. That transaction cleared the 40-man space that made the Sánchez claim possible. One outfielder out, one in — with the incoming player carrying a different profile and a different set of limitations.

The postseason ineligibility clause is the asterisk that shapes everything here. Sánchez is, in effect, a two-week rental with no playoff extension. If Arizona holds on to a Wild Card spot, he watches from the stands. That context makes this less a roster-building decision than a short-term attempt to squeeze production out of a player who, at his best, offers a useful combination of skills — and who is available precisely because that best has been elusive this year.

The numbers

Sánchez's career arc is the story within the story. Per the report, his home run totals ran between 13 and 18 in every season from 2021 through 2025 — a band of consistency that produced 73 home runs across 2,030 plate appearances over that five-year stretch. His combined slash line for that period was .242/.309/.424, with a 26% strikeout rate described as a few ticks higher than normal and an 8.2% walk rate characterized as right around par. FanGraphs credited him with 5.5 wins above replacement over that span — a bit more than a win per year, per the report.

The platoon split is pronounced and worth understanding. Against right-handed pitching, Sánchez has posted a .256/.325/.450 line and a 112 wRC+ over his career, per the report. Against left-handed pitching, those numbers fall sharply to .178/.228/.279 and a 38 wRC+. For a club that would be deploying him primarily against right-handers in a two-week window, that split is the operative number.

Defensively, Sánchez came into this season with 13 Defensive Runs Saved and a +1 Outs Above Average grade, per the report — modest but positive marks that suggested a competent outfielder. He also swiped 29 total bases across the 2024 and 2025 seasons combined, a late-career development in the stolen-base department that added another dimension to his profile.

This season, however, the numbers have moved in the wrong direction across the board. Per the report, Sánchez has only eight home runs, is drawing fewer walks than usual despite a slightly lower strikeout rate, and has seen his defense regress sharply — minus-10 DRS and minus-8 OAA. The report notes he has made a few gaffes that failed the eye test, and the advanced metrics agree. That defensive decline is what makes this claim a genuine gamble rather than a straightforward reclamation project.

The Blue Jays had acquired Sánchez heading into this season, sending Joey Loperfido back to Houston in the process, per the report. That it did not pan out is, in the most direct sense, why he was available on waivers at all.

Where the club stands

Arizona enters this stretch at 79-71, third in the NL West and 11.5 games back of the division lead. The more relevant number is the Wild Card standing: 4th, 2.5 games relative to the cut line, with the club having dropped its last two. The upcoming schedule at Chase Field includes a Tuesday matchup with the Miami Marlins with Michael Soroka projected against Janson Junk, followed by Merrill Kelly against Ryan Gusto on Wednesday. The New York Yankees come to Chase Field on Friday, September 18.

A week removed from what has been a busy stretch of roster activity — Corbin Burnes was activated from the injured list and returned to the rotation, though still on a strict pitch count while regaining feel for his breaking pitches — the Diamondbacks are clearly in triage mode, trying to assemble the most functional group they can for the final two weeks of the regular season. The expanded September roster, which allows clubs to carry 28 players through the end of the regular season under general league rules, gives Arizona some flexibility in how it absorbs Sánchez without displacing a critical piece elsewhere.

What we don't know yet

The report does not specify when Sánchez will report to Arizona, what his role will look like once he arrives, or how the club intends to deploy him given the pronounced platoon split. It is also not yet clear how the active roster will be configured to accommodate him — the mechanics of who, if anyone, moves to make room have not been reported.

Whether the Gurriel Jr. designation leads to a trade, a release, or an outright assignment also remains unresolved, per the available reporting.

What to watch

The immediate question is how quickly Sánchez is placed on the active roster and whether Arizona uses him in a platoon role against right-handed pitching, which is where his career numbers suggest he can still contribute. The Marlins series this week offers a relatively low-stakes environment to reintegrate him before the Yankees arrive Friday.

The larger watch item is the Wild Card race itself. At 2.5 games relative to the cut line on a two-game skid, Arizona does not have the margin to treat any roster decision as inconsequential. Sánchez's postseason ineligibility means his value is entirely contained within the next two weeks of regular-season play — a narrow window that the club, per the report, is explicitly counting on him to help fill.
