The 21-year-old has held his own this season with a .285 average to go along with 14 extra-base hits, including eight doubles an five home runs, in 165 at-bats. He has also stolen six bases in nine attempts. Sure, he has had some stretches in which he has trouble with patience at the plate, but he has kept composure in a lost season for the Red Sox.
In the field, he has shown that changing positions has not affected him as he has made some great reads in center while also playing eight somewhat successful games at second. He has just two errors combined in 45 games (44 started) this season. While he does not have a long-term spot at second, the Red Sox have a chance this offseason to make sure he does have a spot either on this team or as a part of a big picture deal in a trade for a front-line starter or a power bat.
Betts has shown versatility, which benefits the Red Sox and other teams. If injuries occur, then he could slip right in for any outfield spot while also sliding into second in a pinch.
Not only that, but he has a quality combination of speed and power that has been the norm for recent players success. Players like Andrew McCuthchen, Mike Trout, Yasiel Puig and even Carlos Gomez all have shown to have power and speed in their repertoires. However, Betts might not be as powerful or fast as any of these players. He might not pan out and could be a one-and-done player, but taking a chance on him might be the best option for the Red Sox mobing forward.
If the Red Sox decide to sell high on the prospect, then they need to get something that improves this team now. It could be Giancarlo Stanton or even a Chris Sale, but, whatever the Red Sox decide to deal for this offseason, Betts is a candidate to be in the deals.
Betts has shown that he can play at a high level and that can benefit the Red Sox in multiple ways. But I say trade him before he fizzles out.
