The Boston Red Sox have been trying to thread the needle between winning now and developing superstar prospects, and it's created sticky situations galore. Second baseman Kristian Campbell joined the team straight out of spring training and signed an eight-year extension shortly thereafter.

Abreu slashed .245/.321/.471 with 13 home runs, 32 RBI, 28 runs scored, four stolen bases and a 24:54 BB:K across 234 plate appearances before getting hurt.

Aroldis Chapman, the Red Sox' 36-year-old lefty closer, may be their most attractive trade asset.

Brady House is manning the hot corner for the Washington Nationals, and he will join a promising young offensive core that already includes James Wood, CJ Abrams and Luis García Jr.
