The biggest strength for the Mets this year has been the bullpen, with the relief corps posting a 2.88 ERA that ranks fifth in the majors, to go along with an MLB-leading 11.7 K/9 and a stingy .199 opponents' batting average.

Closer Edwin Díaz has returned to the ninth inning, while Adam Ottavino is once again serving as a proven setup option, but it's the overall depth of the bullpen that has made it such a weapon.

Former All-Star closer Jorge López (18 G, 2 SV, 5 HLD, 2.04 ERA) has been a great pickup on a one-year, $2 million deal, while left-hander Jake Diekman (14 G, 3 HLD, 3.86 ERA, 13.1 K/9) has brought some balance as a lefty with swing-and-miss stuff.

The 31-year-old has a 0.47 ERA, 1.05 WHIP and 15.2 K/9 with five wins, one save and three holds in 13 appearances, and he has struck out 32 of the 75 batters he has faced while emerging as a lights out option.
