Prospectus’ Jeff Erickson, in his Fantasy Focus column (subscription), identifies Graves as one of three closers who are likley to lose their job this year.
Erickson points out that post-All-Star break, Graves had a 7.23 ERA, 1.98 WHIP, .349 batting average allowed and an 11/8 K/BB ratio over 18 2/3 innings. I didn’t realize he was that bad.
Of the candidates to replace him, I think Wagner is most likely, but (like Erickson), I think Acevedo might be the best. Another thing I did not know: Acevedo threw 17 scoreless innings in 12 relief appearances.
