Let's break down the major moves:
Carlos Gomez Heads to Houston
Astros deal for Carlos Gomez, Mike Fiers
The Astros landed the right-handed bat and starting pitcher they coveted Thursday, striking a deal with the Brewers for outfielder Carlos Gomez and right-hander Mike Fiers in exchange for four prospects -- outfielders Brett Phillips and Domingo Santana, right-hander Adrian Houser and left-hander Josh Hader.
Houston's View: Astros perspective on Gomez trade
"We are serious about doing some damage here," Astros GM Jeff Luhnow said. "I imagine days when we have Gomez, (George) Springer and (Jake Marisnick) in the outfield together."
Milwaukee's View: Brewers take on the Carlos Gomez trade
"We got four young players that we feel are very talented players. It was tough with Carlos; it was very emotional to tell him this again after what he went through yesterday. All the excitement he has brought to the organization and all the fun he has brought to the organization made it tough. It had to be difficult for him because he loved the organization.
Blue Jays Acquire David Price
Tigers trade David Price to Blue Jays
The Blue Jays became instant contenders in the American League after they pulled off yet another blockbuster trade on Thursday afternoon by acquiring former AL Cy Young Award winner David Price from the Tigers. Toronto sent left-handed prospects Daniel Norris, Matt Boyd and Jairo Labourt to the Tigers as part of the deal.
Detroit's View: Tough to see David Price go, but show goes on
Players gave Price handshakes and hugs in the visitor's clubhouse at Orioles Park at Camden Yards before he exited. Those players then went on to prepare to play out the rest of the season without the team's best pitcher.
Toronto's View: Blue Jays land David Price from Tigers
The Toronto Blue Jays landed a true ace for their starting rotation just one day before the non-waiver trade deadline.
Pirates Add Joakim Soria to Bullpen
After trading David Price earlier in the day, the Detroit Tigers announced just before the start of tonight's game against the Baltimore Orioles that closer Joakim Soria had been traded to the Pittsburgh Pirates for minor-league shortstop JaCoby Jones.
Angling to turn a strong relief corps into an even more formidable unit, the Pirates spent the final days ahead of the non-waiver trade deadline today upgrading their bullpen.
Dustin Ackley heads to New York
Yankees get Dustin Ackley from Mariners
The Yankees joined the busy buildup to Friday's 4 p.m. ET non-waiver Trade Deadline with a smaller move on Thursday, acquiring infielder-outfielder Dustin Ackley from the Mariners in exchange for Minor League outfielder Ramon Flores and Minor League right-hander Jose Ramirez.
There is a belief in scouting circles that the Yankees traded a better outfielder for Dustin Ackley, whom they acquired from the Mariners for outfielder Ramon Flores and right-handed pitcher...
Seattle's View: Dustin Ackley trade symbolizes continuing dark days of Mariners
The Mariners seem stuck in limbo with leadership that can’t fix a franchise missing from the playoffs for 14 years.
Dodgers fare best in deal with Marlins, Braves
There were many moving parts to the three-team, 12-player (and a Draft pick) deal involving the Dodgers, Braves and Marlins, announced officially on Thursday afternoon. Los Angeles acquired starting pitchers Alex Wood, Mat Latos and Bronson Arroyo, relievers Jim Johnson and Luis Avilan, slugger Michael Morse and infield prospect Jose Peraza. The Dodgers also received cash considerations from both clubs.
Los Angeles' View: Dodgers rebuild rotation with 13-player trade
There was no superstar added to their rotation, but the Dodgers picked up two helpful and needed arms to leave them a solid starting five.
Atlanta's View: A terrible Braves trade, right? Not so fast, my friends
You might hate this trade. I understand if you do. I hope you'll understand when I say: I happen not to hate it.
After a day of limbo, the Marlins finalized a three-team, 13-player trade that sends Mat Latos and Michael Morse to the Dodgers in exchange for three minor-league pitchers.
Cleveland Sends Brandon Moss to St. Louis
Cardinals get Brandon Moss from Indians
On the heels of consecutive shutouts that underscored the club's need for an offensive jolt, general manager John Mozeliak swung a player swap with Cleveland early Thursday morning to bring Brandon Moss and his power potential to St. Louis.
St. Louis' View: Cards seek power, grab Moss from Indians
A few hours after their left fielder Matt Holliday sustained his second leg injury of the season, the Cardinals moved swiftly to complete a deal with Cleveland that brings them lefthanded-hitting outfielder and first baseman Brandon Moss.
Cleveland's View: Indians have new goals in wake of Brandon Moss, David Murphy trades
GM Chris Antonetti says the second half of the season will be about assessing their current club and seeing as many young players as possible in preparation for next year.
Rumors of More to Come
Even after all the trades listed above a number of rumors are still floating around and the opportunity to improve is still out there for contenders willing to pay the price. Here are the top remaining rumors to watch as the non-waiver trading period winds down.
Chicago has long been rumored to be considering a move involving the up-and-down 25-year-old infielder.
White Sox Aggressively Pursuing Bat; Interested In Upton, Cespedes
The White Sox are making a late push to add a bat.
Orioles, Brewers Discussing Gerardo Parra
The Orioles aren’t alone in their pursuit of Parra as the Angels and Mets have also been linked to him recently.
The Mets are making a last minute effort to land Jay Bruce from the Reds.
The Giants and Reds are in "active discussions" regarding right-hander Mike Leak. One would imagine that a move to the spacious AT&T Park would do wonders for Leake, who could see a nice boost to his ERA by making a drastic shift to one of the game’s more pitcher-friendly environments.
