Karablog: Top closer trends of 2018 and strategies for next season

Blake Treinen, one of the top closers in 2018, was a late pick in most fantasy drafts. Kelley L Cox-USA TODAY Sports

The AL West tells us quite a bit about why investing in closers -- either for dynasty purposes or early in redraft formats -- can be so dangerous. Back in March, the closers for this division were, in order of their average draft position, Edwin Diaz and Ken Giles in Round 11, and then considerably later on it was Blake Treinen, Blake Parker and Alex Claudio. Diaz has had an incredible season, as has late-round pick Treinen, but Giles was bad and then traded, Parker has shared the role and does not appear to have it today while Claudio has one save all season, and recently started a game.
