July 31: Astros acquire RHP Zack Greinke and cash from D-backs for 1B/OF Seth Beer, RHP Corbin Martin, RHP J.B. Bukauskas, and INF/OF Josh Rojas

The Astros pulled off a stunning blockbuster at the Trade Deadline buzzer, scoring D-backs ace Zack Greinke for a package of four prospects in Beer (Houston’s No. 3), Bukauskas (No. 4), Martin (No. 5) and Rojas (No. 22). Greinke, 35, is in the middle of another strong season with a 2.87 ERA and a 0.94 WHIP over 141 innings. He signed a six-year deal for $206.5 million after the 2015 season, so Houston will have him through 2021. That is key for the Astros, who could lose starters Gerrit Cole and Wade Miley to free agency after this season. Arizona was willing to unload its top starting pitcher in exchange for a haul of young talent that adds to a farm system that has been on the rise and improves even more with this quartet.


July 31: Braves acquire RHP Shane Greene from Tigers (for RHP Tristan Beck and RHP Dan Winkler) and RHP Mark Melancon from Giants (for LHP Joey Wentz and OF Travis Demeritte)

Along with Tuesday’s move for Rangers righty Chris Martin, these moves added three new arms to an Atlanta bullpen in desperate need of reinforcements. Greene and Melancon entered the fold not long after the Braves blew a 4-1 eighth-inning lead at Washington in an eventual 5-4 victory. Greene was an All-Star this season in Detroit, where he picked up 22 saves and dropped his ERA from 5.12 in 2018 to 1.18. Melancon has been a shutdown closer in the past with the Pirates and Nationals, but the 34-year-old has fallen off a bit from that peak. Still, Melancon has posted a 3.38 ERA over 85 1/3 innings for the Giants over the past two seasons, and prior to the trade had a seven-game scoreless streak (8 2/3 innings, nine strikeouts).


July 31: Cubs acquire OF Nicholas Castellanos and cash considerations from Tigers for RHP Paul Richan and RHP Alex Lange

The Cubs added a big bat just before the Trade Deadline in Castellanos, who is hitting .273/.328/.462 with 37 doubles and 11 home runs this season. A free agent at the end of 2019, the 27-year-old righty-swinging slugger will help handle a corner-outfield spot on the North Side, perhaps platooning with lefty bats Kyle Schwarber and Jason Heyward. Richan, a 22-year-old who was a second-round pick in the 2018 Draft and was the No. 16 prospect in Chicago’s system, has a 3.97 ERA and a 1.23 WHIP across 93 innings (17 starts) at Class A Advanced Myrtle Beach this year. A first-rounder in 2017, the 23-year-old Lange was the Cubs’ No. 23 prospect, and he owns a 5.82 ERA in 86 2/3 frames between Myrtle Beach and Double-A Tennessee.


July 31: Giants acquire 2B Scooter Gennett and cash from Reds for a PTBNL

Hitting just .212/.232/.258 over 20 games, Gennett missed the first three months of 2019 with a groin strain and has yet to regain the form he showed from 2017-18 when he broke out and slashed .303/.351/.508 while totaling 50 homers and 189 RBIs. The Giants, who have gotten little offensive output from incumbent second baseman Joe Panik, are hoping the 29-year-old Gennett — a free agent after the season — can recover some of that pop down the stretch as they attempt to make a surprising run for a National League Wild Card spot.

July 31: Astros acquire RHP Aaron Sanchez, RHP Joe Biagini and OF Cal Stevenson from Blue Jays for OF Derek Fisher

While Houston’s acquisition of Zack Greinke from the D-backs for four prospects stole the headlines, the club also added Sanchez and Biagini in a deal with the Jays to further augment its pitching staff. Sanchez has struggled with blister problems in recent seasons and owns a 6.07 ERA this year, but he was the American League ERA leader in 2016 (3.00) and has experience pitching in the rotation and the bullpen. He’s also under control through 2020, giving the Astros some insurance with Gerrit Cole, Wade Miley and Collin McHugh set to hit free agency after this season. Biagini, meanwhile, is controllable through 2022 and will provide some right-handed depth for a bullpen that just lost All-Star Ryan Pressly to the injured list. Fisher was once a Top 100 prospect for the Astros, but he hasn’t been able to break through as a regular component of the team’s big league roster.


July 31: A’s acquire Tanner Roark from Reds for OF Jameson Hannah

Roark gave the Reds a 4.24 ERA over 21 starts after joining the club in an offseason trade with the Nationals, and the impending free agent brought back an outfielder who ranked as the A’s No. 8 prospect and was a second-round Draft pick in 2018. The 32-year-old Roark addresses Oakland’s need for a veteran starter as the club looks to make another postseason push.


July 31: D-backs acquire RHP Mike Leake from Mariners

While Arizona sent Zack Greinke to the Astros in a last-minute blockbuster that brought back four prospects, the club also picked up Leake from the Mariners. It was the second rotation addition of the day for the D-backs, who acquired Zac Gallen from the Marlins for prospect Jazz Chisholm. Leake, who needed to waive his full no-trade clause for the deal to go through, is still owed $20 million guaranteed — including the $5 million buyout on his $18 million mutual option for 2021 — though the Cardinals are paying $4 million of his $15 million salary in ’20. The 10-year veteran owns a lifetime 4.05 ERA, with a 4.40 mark this season, and has made 30-plus starts in each of the past seven years.


July 31: Phillies acquire OF Corey Dickerson from Pirates for a PTBNL and international bonus pool money

For the second time in as many years, Dickerson will replace Andrew McCutchen in the outfield. The Pirates acquired Dickerson during Spring Training last year to help fill the void in their outfield created by the trade that sent McCutchen to San Francisco. Outfield became a position of need for the Phillies when they lost McCutchen to a season-ending ACL tear on June 3. Dickerson carried a .317/.376/.556 slash line into Wednesday’s game, though the soon-to-be free agent has missed significant time due to injuries this season.


July 31: Twins acquire RHP Sam Dyson from Twins for OF Jaylin Davis, RHP Prelander Berroa and RHP Kai-Wei Teng

An eight-year veteran, Dyson is having a second straight effective campaign with a 2.47 ERA, a 0.90 WHIP and 47 strikeouts over 51 innings. The 31-year-old will bolster a Twins bullpen that also added Sergio Romo from the Marlins a few days ahead of the Trade Deadline. Unlike Romo, who is an impending free agent, Dyson comes with another year of club control beyond 2019.


July 31: Rays acquire RHP Trevor Richards and RHP Nick Anderson from Marlins for RHP Ryne Stanek and OF Jesus Sanchez

The Rays’ pitching staff has been hit hard by injuries, with Blake Snell, Tyler Glasnow, Jose Alvarado and Stanek all sidelined. The club was able to address that problem by sending Stanek to Miami along with Sanchez, who was ranked as its No. 4 prospect (MLB’s No. 33 overall), in exchange for two promising arms who can help now but are controllable through 2024.


July 31: D-backs acquire RHP Zac Gallen for SS Jazz Chisholm

The Marlins have a handful of promising young pitchers on their MLB roster or in the pipeline, and they used one of them to land Chisholm, who was Arizona’s No. 1 prospect and MLB’s No. 59 overall. Gallen made his big league debut earlier this season and has recorded a 2.72 ERA with 43 strikeouts over 36 1/3 innings. The 21-year-old Chisholm, meanwhile, is a toolsy shortstop who has struggled with strikeouts so far in his Minor League career.


July 31: Nationals acquire RHP Hunter Strickland from Mariners for LHP Aaron Fletcher

Washington made its third bullpen addition of the afternoon, and second from Seattle, by dealing for Strickland, who recently returned from the injured list after missing much of the season with a right lat strain. The right-hander opened this season as the M’s closer before going on the injured list. He owns a lifetime 2.98 ERA in the regular season and pitched in 11 postseason games with the Giants. Fletcher, who was ranked as Washington’s No. 21 prospect, has notched a 1.79 ERA with a 10.3 K/9 mark and a 2.2 BB/9 over 32 relief appearances this year, appearing at three Minor League levels.


July 31: Brewers acquire LHP Drew Pomeranz and RHP Ray Black from Brewers for SS Mauricio Dubon

It didn’t look as though Pomeranz would have much trade value as recently as two weeks ago, but a move to the bullpen worked wonders. In 5 1/3 scoreless innings spanning four relief appearances, Pomeranz allowed only one hit and one walk. For Pomeranz, an impending free agent, and Black, a 29-year-old who has made just 28 big league appearances, San Francisco did well to get back Dubon. The 25-year-old, who was ranked as Milwaukee’s No. 3 prospect, has posted a .297 average with 16 homers and nine steals at the Triple-A level this season.


July 31: Nationals acquire LHP Roenis Elias from Mariners for LHP Taylor Guilbeau and RHP Elvis Alvarado

Shortly after picking up Daniel Hudson from the Jays, the Nats added another bullpen piece in Elias, who has spent much of this season as the Mariners’ closer. The 30-year-old lefty is under control through 2021 and owns a 4.40 ERA this season. Guilbeau was the Nats’ No. 15 prospect, while Alvarado did not rank among the club’s Top 30.


July 31: Nationals acquire RHP Daniel Hudson from Blue Jays for RHP Kyle Johnston

Improving the relief corps was clearly a priority for the Nats, who entered Trade Deadline day with the highest bullpen ERA (5.99) in the Majors. After signing a one-year, $1.5 million deal with the Blue Jays in the offseason, Hudson has enjoyed a strong campaign, posting a 3.00 ERA in 48 innings. To acquire him, Washington surrendered Johnston, who was ranked as the team’s No. 27 prospect.


July 31: Dodgers acquire INF Jedd Gyorko, 2019-20 international cap space and cash considerations from Cardinals for LHP Tony Cingrani and RHP Jeffry Abreu

Gyorko hit just .196/.274/.304 for the Cardinals this season and hasn’t played in the Majors since June 7 due to a lower back strain. However, the veteran right-handed hitter is expected to return from the 60-day injured list soon and should give the Dodgers another versatile option. The 30-year-old has experience at every infield position, though he’s spent the bulk of his time at second base and third base. Gyorko also was solid at the plate for St. Louis from 2016-18, slashing .259/.331/.463 with 61 homers. The Dodgers didn’t surrender any 2019 contributors in the deal, with Abreu in Rookie ball and Cingrani out for the season after having left shoulder surgery in June.


July 31: Astros acquire C Martin Maldonado from Cubs for INF/OF Tony Kemp

Not only is Martin Maldonado on the move for the second time in just over two weeks, he also is joining the Astros for the second straight stretch run. The 32-year-old backstop was acquired by the Cubs from the Royals for lefty Mike Montgomery on July 15 but found his role limited once Willson Contreras returned to health. Houston traded for Maldonado last July, too, giving him regular playing time in the second half and in October while Brian McCann battled injuries. He will provide depth behind starter Robinson Chirinos this time around before hitting the open market.

On the other side of the deal, Kemp — who was designated for assignment by Houston earlier in the week — brings versatility to a Cubs team that values players who can cover multiple spots on the diamond. The 27-year-old has a career-high seven homers in 186 plate appearances this season.


July 31: Rays acquire 1B Jesus Aguilar from Brewers for RHP Jake Faria

The Rays had been connected to a number of right-handed bats leading up to the Trade Deadline, and Aguilar fills that need. After making the All-Star team in 2018, the slugger has struggled for much of ’19, though he has shown some improvement lately. Since the start of July, Aguilar has hit .298/.346/.574 with three homers in 52 plate appearances. Faria, meanwhile, will provide some depth for an ailing Brewers pitching staff.


July 31: Rangers acquire RHP Nate Jones, international slot compensation and cash considerations from White Sox for RHP Joe Jarneski and RHP Ray Castro

The Rangers increased their international bonus pool money by $1 million, which will help the club finalize the signing of international free agent outfielder Bayron Lora, according to’s T.R. Sullivan. The Rangers agreed to a $4.2 million signing bonus with Lora on July 1, according to’s Jesse Sanchez, but the deal has yet to be announced because the club still needed to add international slot money. Jones is recovering from surgery to repair a torn flexor tendon in his right forearm on May 13 and will go on the 60-day injured list for the Rangers.
