The Philadelphia Phillies remain one of the top teams in Major League Baseball and are leading the National League East division; even still, the team has room to improve. The Phillies won four of their last five games and got a key series victory against division rival New York Mets this past week. As the trade deadline nears, one key area that the Phillies need to improve in if they want to make a deep playoff run is their bullpen. Bleacher Report’s Tim Kelly believes that the Phillies’ biggest need is a high-leverage reliever.
