The Mets continue to look at bolstering their bullpen after acquiring closer Edwin Diaz from the Seattle Mariners earlier this week.
Talking on WFAN on Wednesday night, Mets GM Brodie Van Wagenen said that the team needs left-handed relief help to give manager Mickey Callaway better matchup options. He did mention they were impressed by the limited work from Daniel Zamora after he was promoted.
Britton, 30, finished the 2018 with a 3.10 ERA, 1.23 WHIP and 4.22 FIP, while striking out 34 and walking a whopping 21 batters in 40.2 innings between the Baltimore Orioles and New York Yankees.
The left-handed Britton had his best season in 2016, when he had a career-high 47 saves and 4.2 bWAR. He was an All-Star that year, as well as in 2015 for the Orioles.
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.
