The Yankees dismissed hitting coach Kevin Long after 11 years in the organization, part of the fallout from a disappointing 2014 season in which the club finished 12th in the American League in runs scoring.
He wasn't out of work for long, with the Mets quickly bringing him across town.

With the Subway Series on deck -- the Mets' first meeting with the Yankees since early in the season -- Long said the games carry little personal meaning.
"Zero, not at all," he said. "I feel like I fit in here with the Mets. I feel like I'm a New York Met now and that's the bottom line."
Instead, he placed the focus on the larger implications of the series.
"It's just another series and another team," he said. "It's an important series for them, it's an important series for us, it's the battle of New York and it's big. But just because I worked over there the last 11 years, it doesn't have any more meaning or less meaning compared to any other series."
Indeed, both the Yankees and Long have moved on. The Yankees enter the Subway Series second in the AL in runs per game, behind only the Blue Jays.
Meanwhile, the Mets' second-half surge has rocketed them from bottom of the league in run-scoring to sixth.
"I'm not doing anything different than I have done in the past," Long said. "I'm doing exactly the same stuff. I come to work and give the organization and the players everything I've got every single day. That's my gratification. The gratification is the team playing well."
