The 2015 Major League Baseball trade deadline has passed.

There were a lot of trades across the league that will benefit teams for quite a while. On the other hand, some teams didn't make the necessary moves to improve their roster to the fullest.

Let's take a look at the biggest winners and losers this year.

Winners

Toronto Blue Jays

The Toronto Blue Jays had a phenomenal trade deadline. They added two quality players on both sides of the baseball. It began when they traded for Troy Tulowitzki. They had to give up Jose Reyes, but this investment will be worth it. In Tulowitzki's debut, he hit a home run with the Blue Jays. But, Canada's lone team still desperately needed pitching. So, they struck a deal with the Detroit Tigers for David Price. Price and the Blue Jays know each other very well considering Price pitching in the American League East with the Tampa Bay Rays for seven seasons. The Blue Jays could make their first playoff appearance since 1993.

San Diego Padres

The San Diego Padres still think they can win the National League West despite their losing record at the moment. The Padres were involved in an enormous amount of trade rumors, but didn't make the huge splash that MLB experts firmly believed they would make. It will be tough for the Padres to catch the Los Angeles Dodgers and San Francisco Giants in that division. The Padres may not even get a wild card spot this year.
