You might be surprised to know, ex-Yankee edition:

— The White Sox’s Anthony Swarzak (5.52 ERA in 26 games/31 innings with the 2016 Yankees) has thrown the most innings (19 2/3) without giving up a run this season, yielding just four hits and striking out 22. Relying on a mid-90s fastball and better-than-ever slider, the journeyman righty recently had a stretch in which he threw 9 2/3 no-hit innings, walking one and whiffing 12.

Despite having Nate Jones, Jake Petricka and Zach Putnam on the DL, the White Sox have the majors’ second-best bullpen ERA (2.24) in part because Swarzak, former Yankees closer David Robertson and former Yankees farmhand Tommy Kahnle have combined for 42 appearances and a 1.17 ERA. Kahnle is third in the majors with 16.7 strikeouts per nine innings, behind only Craig Kimbrel and Kenley Jansen.

— Pittsburgh’s Ivan Nova is averaging 0.66 walks per nine innings. The only better marks for pitchers who qualified for the ERA title: Carlos Silva in 2005 (0.43), Babe Adams in 1920 (0.62) and Christy Mathewson in 1913 (0.62).

— Ben Gamel and James Pazos were dealt in separate trades to the Mariners for essentially the same reason: The Yankees anticipated having 40-man roster difficulties for the December Rule 5 draft and felt they had better outfield and relief prospects than that duo.

Gamel, the MVP of the International League last year (he was traded the day after being named), stepped in for the injured Mitch Haniger (who had made himself a Rookie of the Year contender). And now Gamel has done the same. Gamel often was likened to another B.G. developed by the Yankees, Brett Gardner, and in his first 18 games this season, is hitting .309 with a .912 OPS.

In 18 games for the Yankees, the southpaw Pazos had a 5.40 ERA, and lefties were 7-for-19 with an .874 OPS against him. In 19 games for the Mariners, Pazos has a 2.65 ERA, and lefties are 3-for-22 without an extra-base hit and with a .367 OPS.
