The left-hander has worked extensively with Mickey Callaway in the past with the Cleveland Indians during a time period where he was one of the top relievers in the game.
Miller, 33, is coming off a rough season in which he dealt with a shoulder impingement. In 37 appearances, he had a 4.24 ERA, 3.51 FIP, 1.38 WHIP, 45 strikeouts, and 75.3% runners stranded percentage.
However, in 2017, he was among the most dominant relievers in baseball with a 1.44 ERA, 1.99 FIP, 0.83 WHIP, 95 strikeouts, and 87.1 % LOB (left-on-base) percentage 66 2/3 innings.
The year prior, that was split between the New York Yankees and the Indians, was even more impressive highlighted by his 1.45 ERA, 1.68 FIP, 0.69 WHIP, 123 strikeouts, and 95.7% LOB percentage in 74 1/3 innings.
Over time, he found his niche as a reliever and was later dealt for top prospects himself in 2016 as the Yankees acquired Justus Sheffield and others for the reliever’s services.
The Mets currently have only one left-hander on the 40-man roster has recorded relief appearance at the MLB level in this decade in Daniel Zamora, who will be given a shot to earn a role in the team’s bullpen this spring. Miller, unsurprisingly, has held his own against his same-handed opponents as over the last three years, he has limited them to averages of .161, .164, and .227 in each of the last three seasons.
There’s no question that Miller could be very useful to the Mets next season, but price will almost certainly be a factor for a reliever who dealt with injuries this past season, has a very high usage rate over the last few years, and will be 34 before the end of May next season.
Jon Heyman of Fancred currently projects Miller to receive a one-year, $13 million contract while an expert he co-wrote the article with projects him to get a two-year, $20 million contract.
At that price, the Mets could very well be in position to land the reliever that had a close bond with Callaway, as Morosi pointed out.
