Report: Top free-agent reliever O'Day seeking 4-year deal

The most accomplished reliever on the open market has reportedly set his price.

Darren O'Day is seeking a four-year deal in the $28-to-$36-million range, according to Ken Rosenthal of FOX Sports.

The price for top-tier relief help has been at a premium in recent years, as teams continue to commit more resources into building their bullpens.

Andrew Miller agreed to a four-year, $36-million deal with the New York Yankees last winter, while David Robertson landed a four-year, $46-million deal with the Chicago White Sox. The Boston Red Sox traded a package of four prospects to land Craig Kimbrel from the San Diego Padres earlier this month.

O'Day was an All-Star for the first time in 2014, and the right-hander owns an impressive resume, producing a 1.79 ERA and 0.93 WHIP over the past three seasons, striking out 214 in 196 innings.

The Boston Red Sox and Detroit Tigers appeared to be main suitors for O'Day, though its unknown if they're still in the market after each acquiring a closer.
