The New York Yankees are one of the teams in serious pursuit of left-handed reliever Andrew Miller, who is also drawing interest from the Boston Red Sox and other teams, sources told ESPN's Buster Olney.

His agent, Mark Rodgers, said earlier this month that the reliever is generating strong interest from several teams in the market for a closer this offseason.

"I think Andrew's evolution in the bullpen and his numbers this year fortify the belief in baseball that he's a closer-in-waiting -- and maybe the time for waiting is over," Rodgers said at the MLB general managers meetings.

Yankees closer David Robertson, who also is a free agent this offseason, is looking for "Papelbon money" in initial talks with teams, a baseball official with knowledge of the discussions told ESPNNewYork.com's Andrew Marchand earlier this month.

In 2011, the Philadelphia Phillies signed Jonathan Papelbon to the richest overall reliever contract, a four-year, $50 million deal. If Papelbon finishes 15 games in 2015, his contract will vest for a fifth year at $13 million more, making it a total of five years and $63 million.

Robertson, who will turn 30 in April, completed his first year as a closer in 2014. He finished the season 4-5 with a 3.08 ERA, converting 39 saves in 44 opportunities.

He rejected the Yankees' one-year, $15.3 million qualifying offer. If the Yankees do not re-sign him, they do have an internal closer option in 26-year-old Dellin Betances, who was the superior reliever to Robertson in 2014, earning a spot on the All-Star team and finishing third in the AL Rookie of the Year voting.

If the Yankees were to sign Miller, it would not necessarily eliminate their pursuit of Robertson, an official with knowledge of the team's thinking told Marchand on Monday. The Yankees could construct a really strong bullpen led by the three-headed monster of Robertson, Miller and Betances. Robertson would close with Miller and Betances providing a strong bridge from the starters to the ninth inning.

However, the source said the Yankees currently aren't prepared to pay Robertson the $50-plus million for four years he is seeking. If Robertson's price tag comes down, then the Yankees' interest in his return would increase.

The Baltimore Orioles acquired Miller from the Red Sox before the trade deadline last season, and the 29-year-old left-hander was dominant out of the bullpen for the eventual American League East champions, going 2-0 with a 1.35 ERA and one save.

He held left-handed batters to a .163 average last season and was even more effective vs. righties, holding those hitters to a .145 average. Between the Red Sox and Orioles he finished last season 5-5 with a 2.02 ERA and the one save, striking out 103 batters in 62 1/3 innings.

Miller was a starting pitcher at the beginning of his career, but the Red Sox moved him to the bullpen full time in 2012. He has a 30-38 record with a 4.91 ERA and one save in nine seasons with the Detroit Tigers, Florida Marlins, Red Sox and Orioles.

He was paid $1.9 million in 2014.
