Monday's deadline for trades without waivers produced a total of 14 deals involving 20 clubs, 38 players, three international bonus slots and one player to be named later. We've covered them from a team-by-team perspective all over MLB.com, so here we'll examine the prospect costs in the four biggest transactions of the day.
Dodgers get RHP Yu Darvish
Rangers get 2B/OF Willie Calhoun, RHP A.J. Alexy, INF Brendon Davis
Already cruising toward the playoffs, Los Angeles picked up the biggest difference-maker who changed addresses and now can throw a Clayton Kershaw-Darvish 1-2 punch at opponents in October. While they did give up a Top 100 Prospect in Calhoun (No. 69 on MLBPipeline.com's Top 100 list), the Dodgers didn't have to part with any of their three elite prospects: right-handers Walker Buehler and Yadier Alvarez, and outfielder Alex Verdugo. That's a win for L.A.
• Ranking prospects traded before Deadline
Texas did land one of the game's best power prospects in Calhoun, though its package pales in comparison to what the Yankees got last July for Albertin Chapman, who like Darvish was headed for free agency four months later. Darvish should have had more value as a starter compared to a reliever, but with the new collective bargaining agreement providing the Rangers only a compensation pick before the third round of the Draft if he walked as a free agent, they had to take what they could get. It's a decent haul but perhaps not as overwhelming as Rangers fans might have hoped for.

Calhoun likely will wind up in the outfield, though his combination of pop and patience still means he'll profile as a regular there. Alexy is thriving in low Class A at age 19 and shows the potential for three solid offerings once he's fully developed. Davis is an extremely projectable future third baseman with power potential.
Yankees get RHP Sonny Gray, international bonus slot
Athletics get OF Dustin Fowler, SS/OF Jorge Mateo, RHP James Kaprielian
Gray can't become a free agent until he completes two more seasons, so his long-term value made him more attractive to clubs than Darvish. He won't necessarily dominate like Darvish can, but Gray can slot in as the Yankees' No. 2 starter through the end of 2019. In return, New York surrendered one Top 100 Prospect (Fowler, No. 77) and two more prospects who have graced the list in the past.
Like the Dodgers, the Yankees didn't have to part with their most desirable prospects (infielder Gleyber Torres, outfielder Clint Frazier). They also held onto outfielder Estevan Florial, who might have the best overall tools in baseball's deepest farm system. That depth made it easier to part with three high-ceiling prospects.

Some might second-guess Oakland for getting two players who are out for the season with injuries, but it's hard to argue with the upside they received in return. Fowler, who ruptured the patellar tendon in his right knee during his first big league game on June 29, has 20-20 potential and center-field skills. There are evaluators who believe he, not Frazier, is the best outfield prospect in New York's system.
While Mateo's stock has slipped since he led the Minors with 82 steals in 2015, he still possesses the top-of-the-scale speed and deceptive pop that prompted Jose Reyes comparisons. If he's too erratic to stick at shortstop, his tools still will profile well at second base or center field. Kaprielian is recovering from Tommy John surgery in April, but when healthy he flashed four plus pitches and control to match.
Red Sox get RHP Addison Reed
Mets get RHP Stephen Nogosek, RHP Jamie Callahan, RHP Gerson Bautista
Boston desired bullpen help but didn't have a lot to offer because president of baseball operations Dave Dombrowski has made several trades that depleted what was baseball's best farm system when he took over in August 2015. The Mets had a successful closer who wasn't going to merit a qualifying offer to trigger compensation when he became a free agent following the season.

It wasn't a blockbuster, but both teams should be happy with what they got. The Red Sox picked up a quality setup man for Craig Kimbrel, though the Yankees are now the favorites in the American League East after all of their July wheeling and dealing. The Mets received three bullpen righties with value.
Nogosek can miss bats with his 92-96 four-seam fastball, slider and cutter. Callahan, who has a mid-90s fastball and a cutter, is nearly ready for the Majors. Bautista is more raw but has a bigger arm than the other two, showing a fastball that can hit 100 mph.
Cubs get LHP Justin Wilson, C Alex Avila
Tigers get 3B/1B Jeimer Candelario, SS Isaac Paredes
Monday's first trade made a lot of sense for both sides, with Chicago and Detroit landing players that were more valuable to them than the other side. A luxury as a closer on the American League's third-worst club, Wilson becomes the best left-hander in the Cubs bullpen. Pending free agent Avila provides veteran insurance behind young catchers Wilson Contreras and Victor Caratini.
Though Candelario (No. 92 on the Top 100) is a solid hitter and defender who's ready to play every day in the Majors, he wasn't going to get that opportunity in Chicago with Kristopher Bryant and Anthony Rizzo blocking him. Paredes, who's holding his own as an 18-year-old in low Class A, faced a similar logjam down the road with the Cubs but immediately becomes the best middle-infield prospect in the Tigers' system.
