Yankees get:
3B Ryan McMahon
Rockies get:
LHP Griffin Herring
RHP Josh Grosz
Yankees grade: B
For Yankees fans who wanted Eugenio Suarez to fill the hole at third base, this looks like a big letdown considering McMahon is hitting .217/.314/.403 with 16 home runs — compared to Suarez’s 36 — and ranking second in the majors in strikeouts while playing half of his games at Coors Field. Away from Colorado, he has hit just .189 with five home runs. Consider the positives, however:
-
He has signed through 2027, so he is a solution at third base for the next two years as well (he’ll make $16 million each of the next two seasons).
-
He is an excellent defender, ranking in the 91st percentile in Statcast’s outs above average.
-
He ranks in the 86th percentile in walk rate.
-
He ranks in the 98th percentile in average exit velocity and 87th percentile in hard-hit rate.
-
He might get the “leaving Coors Field” boost, where his road numbers adjust to playing his home games in a more normal environment.
That last one is important. The Yankees have experience with this: DJ LeMahieu hit .327 and .364 in his first two seasons with the Yankees after leaving the Rockies. Yes, the strikeouts are the big concern here with McMahon, and while he is not having his best season, at the minimum, he upgrades the defense and gives the Yankees a little more power. I suspect McMahon won’t hit .189 with the Yankees and could prove to be a sneaky good addition.
Rockies grade: C
While McMahon’s name had been on the rumor mill, it’s still a mild surprise the Rockies actually traded him. First, they rarely make trades of any sort, especially significant ones, and they especially rarely trade their homegrown players such as McMahon. So, at least good for them for doing something that probably makes sense.
Did they get much in return? Herring was a sixth-round pick last year from LSU, where he pitched in relief. The Yankees turned him into a starter, and Herring has mowed through two levels of Single-A with a 1.71 ERA and 10.3 K’s per nine. Primarily a fastball/sweeper guy at LSU, his changeup has proven a big weapon as right-handed batters are hitting just .159 against him.
A college pitcher from a high-profile program such as LSU dominating the low minors usually doesn’t tell us much, except in this case, Herring’s lack of experience and successful transition to a bigger workload is a huge positive. Herring didn’t crack Kiley McDaniel’s top 10 Yankees prospects in his July update but did make MLB.com’s list at No. 8.
Grosz has spent the entire 2025 season at high A, posting a 4.14 ERA with 94 strikeouts in 85 innings and holding batters to a .211 average. He has a high-spin fastball that sits in the mid-90s, but the secondary stuff needs improvement, and the command is a tick below average (35 walks).
The biggest issue is these are two pitchers who haven’t performed above Single-A and don’t necessarily have elite stuff. The stat lines look good, but the next step to Double-A will be a big test to see how Herring’s fastball plays against better competition and whether Grosz can improve his command. — David Schoenfield
Mets get:
LHP Gregory Soto
Orioles get:
RHP Wellington Aracena, RHP Cameron Foster
Mets grade: C+
Through the end of May, the Mets’ bullpen ranked second in the majors with a 2.78 ERA. Since June 1, however, the Mets rank 27th with a 5.02 ERA, so Soto is a logical addition — and probably won’t be the last reliever the Mets acquire. Part of the problem is Mets’ starters haven’t pitched deep into games and manager Carlos Mendoza ran his top relievers except closer Edwin Diaz into the ground.
The Mets have also been without a reliable lefty with offseason signing A.J. Minter out for the year. They did just activate Brooks Raley, but Soto gives them another lefty option, no doubt thinking ahead to potential playoff matchups against the Phillies (Bryce Harper, Kyle Schwarber), Dodgers (Shohei Ohtani, Freddie Freeman) or Cubs (Kyle Tucker, Michael Busch, Pete Crow-Armstrong). They’re going to need more than one lefty reliever.
Is Soto a good option though? He still has premium stuff with a 97 mph fastball and wipeout slider, and left-handed batters are hitting just .138 against him in 2025 (although two of the eight hits have been home runs). As always, however, throwing strikes is often an issue (4.5 walks per nine), and he has a large platoon split (right-handed batters have a .371 OBP against him). Soto is a good left-on-left on matchup, but his control means he isn’t always the most trustworthy, and the Orioles weren’t using him in a lot of high-leverage situations of late.
Orioles grade: B-
Let the exodus begin. With as many as 11 more potential free agents, the Orioles are going to be busy over the next week. A lot of those trades will look like this one: a couple of second-tier type prospects. Aracena (No. 19 on MLB.com’s Mets list, No. 28 on Baseball America) is a 6-foot-3, 20-year-old right-hander with a 2.38 ERA in low-A, including 84 strikeouts in 64 innings, featuring a fastball in the upper 90s that has topped out at 101. That’s the good news. The “Why did the Mets trade him?” news is that he has walked 35 batters. He has a cutter and a slider, but the profile here suggests he might end up as a reliever. Still, a decent return for a non-elite reliever such as Soto.
Foster is a 26-year-old reliever who crushed Double-A in repeating the level this season (1.01 ERA), although he struggled in his first two outings after a recent promotion to Triple-A (seven runs in 3.2 innings). Given all the trades the Orioles will make, it wouldn’t be surprising to see him pop up in the big league bullpen at some point this season. — David Schoenfield
Mariners get:
1B Josh Naylor
Diamondbacks get:
LHP Brandyn Garcia
RHP Ashton Izzi
Mariners grade: B+
This is the first significant trade heading into the final week before the deadline, and it’s interesting in part because it signifies the Diamondbacks are going to be dealing — Naylor could be the first of a group that might include Eugenio Suarez, Merrill Kelly and Zac Gallen, potentially spicing up the deadline with some intriguing names.
While third base was the Mariners’ biggest offensive need, Naylor gives them a well-rounded hitter who has been one of the top contact hitters in the majors this season, hitting .292/.360/.447 with 11 home runs and the 13th-lowest strikeout rate among qualified hitters. Naylor has done most of his damage against right-handed pitchers, hitting .310/.390/.493 with nine of his 11 home runs. That’s an upgrade over incumbent Luke Raley, who has hit .248/.370/.397 against right-handers but is just 1-for-20 against southpaws, with light-hitting Donovan Solano serving as his platoon partner.
Naylor can play every day and fits somewhere in the middle of the lineup, which ranks in the bottom 10 in the majors in strikeout rate, so his contact ability will be a nice addition. It also improves Seattle’s bench as Raley can now fill in at right field (although Dominic Canzone has been hitting well) or DH, with Jorge Polanco perhaps getting some time at second base over Cole Young. Rookie third baseman Ben Williamson is an excellent defender but has just one home run in 256 at-bats. While Polanco has plenty of experience at third in his career, he hasn’t started there since April 4 as a shoulder issue has limited his throwing.
In other words: The Mariners could still seek an upgrade at third base. The Diamondbacks might wait until July 31 to deal Suarez, hoping that one of the several teams that need a third baseman will give in with a nice package of prospects. The Mariners didn’t give up any of their top 10 prospects here, so here’s guessing that Seattle president of baseball operations Jerry Dipoto and Arizona general manager Mike Hazen aren’t done exchanging text messages.
Diamondbacks grade: B
While Garcia and Izzi didn’t rank in Kiley McDaniel’s top 10 Mariners prospects, that’s not necessarily a knock on their potential: Seattle’s top 10 is loaded with top-100 overall prospects. Garcia was ranked No. 13 on MLB.com’s team list and Izzi No. 16.
Drafted in the 11th round out of Texas A&M in 2023, Garcia was a surprising success story as a starter in 2024, but the Mariners moved him to the bullpen this season, and he just made his MLB debut after posting a 3.51 ERA across Double-A and Triple-A with 42 strikeouts in 33⅔ innings. He throws a mid-90s sinker along with a sweeper and cutter, and held lefties to a .235 average and .255 slugging percentage. He can probably go straight to Arizona’s bullpen right now, with the idea that the Diamondbacks try him as a starter in 2026. He’s a nice sleeper prospect in a trade like this, with at least a floor as a reliever and maybe some upside as a back-end starter.
Izzi is a 21-year-old righty with a mid-90s fastball who was a fourth-round pick out of high school in 2022, but he has struggled at high-A Everett with a 5.51 ERA across 12 starts. His fastball/sweeper combo could eventually work as a reliever, although right-handed batters have hit him as hard as lefties. He’s a development prospect.
Nothing too flashy here, but there wasn’t going to be a huge market for Naylor, and he was competing with the likes of Ryan O’Hearn and Marcell Ozuna in the 1B/DH class, so Arizona probably figured it had to strike first with Naylor, giving the team more time to discuss deals for their other pending free agents. — David Schoenfield
