The Red Sox are looking to be buyers at the trade deadline. The Red Sox designated Pablo Sandoval for assignment on Friday afternoon. The move means that Deven Marrero is the full time starting third baseman, but his production has been low. Marrero is batting .221 on the season in 131 at bats.

With the Chicago White Sox being sellers, the two teams could strike another deal. The White Sox and Red Sox completed a deal that sent Chris Sale to Boston in exchange for some of their top prospects. Now, the Red Sox could try and acquire Todd Frazier.

Frazier is a good fit for Boston

According to Mike Petriello of MLB.com, Boston would be the Perfect Fit for Frazier. With Sandoval gone, and Jhonny Peralta released in the minors, the team doesn't have a proven third baseman on the team. According to Petriello, Fenway Park is a perfect setting for Frazier as he pulls nearly 80% of his hits.

Plus, his hitting chart at Fenway is interesting. The chart shows that if Frazier were to hit at Fenway this season, he would have had a batting average about 41 points higher. Frazier is currently hitting .210 this season and is set to be a free agent this season.

The history between the two is good, since the teams completed the Sale trade. However, it's not about relationships, but the prospects.

The haul for Frazier should be low given his production on the season, so the Red Sox could afford that.

White Sox want to move on from others

The White Sox would also like to trade Melky Cabrera and David Robertson this July. Cabrera is making $15 million this season which could make him a hard player to move. Plus, his defense is below average.

Offensively, Cabrera has value as he is hitting .298 and has 97 hits on the season, including 51 runs batted in. As of today, there have not been any teams linked to Cabrera.

The team would also like to move Robertson. The closer has 13 saves and a 2.87 earned run average. Robertson is making $11 million this season, and could help a contender in a setup role.

Robertson was once rumored to be pursued by the Washington Nationals, but Jon Heyman reported that those rumors have died. However, Dan Hayes of Comcast Sportsnet reported that the White Sox are still looking for teams to take on Robertson.

The White Sox have one of the best farm systems in the league with nine players in baseball's Top 100. The White Sox are wanting to get some of their prospects to the majors in August and September, so moving their older veterans is essential.
