What have been some of the biggest trades so far?

Arguably, the biggest trade so far of this deadline was Eugenio Suárez going to the Seattle Mariners. Here’s a breakdown of the trade:

Who else is involved: The Diamondbacks received 1B Tyler Locklear, RHP Juan Burgos, and RHP Hunter Cranton.

Mariners Grade: A+
Diamondbacks Grade: C+

How do you take advantage of one of the best seasons from a catcher in MLB history? Add more help around him. The Mariners entered the deadline with clear needs at both corner infield positions — they had received a combined 11 home runs from the first basemen (six) and third basemen (five) who were still on their roster — and acquired two of the best sluggers on the market to answer those concerns, all without parting with any of their best prospects.

After acquiring first baseman Josh Naylor last week, Seattle tapped back into Arizona’s slugging factory and added the best power hitter on the market in Suárez, who ranks fifth in MLB and leads all third basemen with 36 home runs in a career year at 34 years old. It marks a reunion with Suárez, who was with the Mariners in 2022 and 2023. 

Seattle, though, is hoping that its work over the past week will have the town partying like it’s 2001. That’s the last time the Mariners won the division, and while it won’t be easy to end that skid — they trail the Astros by five games — they now have one of the most complete rosters in MLB thanks to their massive deadline moves. We already know what their rotation can do when healthy. 

Now, an offense featuring Suárez, Naylor, Cal Raleigh, Julio Rodriguez and Randy Arozarena should be able to lead a charge in the American League. Even if they don’t end up catching the depleted Astros, this now looks like a club capable of making a deep October run.

Tyler Locklear, a second-round pick in 2022 who at one point figured to be the answer at first base in Seattle, was the highest-rated prospect to go in the deal. He possesses some serious raw power, but he struggled in a 16-game big-league sample last year, striking out 20 times in 49 plate appearances. He has gone right back to slugging with 19 home runs at Triple-A.  Juan Burgos could help the Diamondbacks’ bullpen immediately, and Hunter Cranton — a third-round pick last year who has allowed just one run in 10 minor-league relief innings — could in the future. 

Still, while Suárez was only a rental, I’m a bit underwhelmed by the return, considering he’s likely the best (non-Rafael Devers) slugger to get dealt before the deadline. – Kavner
