A flurry of deals Thursday highlighted a busy MLB trade deadline. While many position players and starting pitchers were dealt, the theme of this year's deadline was postseason contenders adding to their bullpen.
Closers Jhoan Duran (Twins to Phillies), Ryan Helsley (Cardinals to Mets) and David Bednar (Pirates to Yankees) were moved in some of the biggest trades of the day; however, no deal was bigger than the blockbuster between the Athletics (48-63 through Thursday) and San Diego Padres (60-49).
San Diego, as it tends to do, swung for the fences, landing closer Mason Miller and starting pitcher J.P. Sears. Those two will help the Padres in their pursuit of a World Series, but the price they paid was steep: the No. 3 prospect in the majors, shortstop Leo De Vries and pitchers Braden Nett, Henry Baez and Eduarniel Nunez. Nett (No. 5), Baez (No. 9) and Nunez (No. 17) rank in the top 20 of the Athletics' farm system, per MLB.com.
It was a shocking deal, particularly to see a prospect of De Vries' ilk get moved.
Prospects like Leo De Vries RARELY get moved at the deadline.

Athletics fans must be disappointed to lose their 26-year-old flame-throwing closer, but this trade offer was impossible to turn down.
A lineup with a bright future before the deadline got even brighter Thursday. De Vries will join a young core with slugging first baseman Nick Kurtz, dynamic infielder Jacob Wilson, outfielder Lawrence Butler and plenty of auxiliary talent.
Leo De Vries is 18.

Nick Kurtz is 22.
Max Muncy is 22.
Jacob Wilson is 23.
Tyler Soderstrom is 23.
Lawrence Butler is 25.
Denzel Clarke is 25.
Shea Langeliers is 27.
Brent Rooker is 30.
Kurtz flashed his massive power July 25 with a four-homer game. Wilson has shown hitting ability as a rookie (.312 BA), and Butler has all the tools to be dynamic on offense and defense.
On top of the main core, outfielder Tyler Soderstrom, second baseman Zack Gelof and catcher Shea Langeliers have shown promise in the big leagues. And, of course, don't overlook veteran DH/OF Brent Rooker, who has many good years left.
There is still work to be done on the pitching staff, a weakness the past few seasons. The Athletics lack an ace or even a high-end starter, though they're starting to accumulate pitching prospects and will need to continue doing to balance the roster.
The Athletics are poised to become the Las Vegas Athletics by 2028, and the way they're building could perfectly align with a return to contention.
