The Yankees' four high-leverage relievers will get a ton of press and rightfully so, but the group asked to pitch in middle innings will have to do its part in what could turn out to be a very heavily used eight-pack of pitchers in 2019.
Right-handers Chad Green and Jonathan Holder plus whoever wins the battle for the final two spots in the bullpen will be expected to be ready to pitch in multiple situations and for varying lengths in their appearances. There is both upside and uncertainty among the last four relievers that will break camp with the Yankees.
Green might be more involved in high-leverage innings as he has been the last couple of seasons. The Yankees would likely prefer to utilize Green in lengthier appearances (think four to six outs), bringing in the 27-year-old to polish off a rocky inning from a starter and then cover some or all of the next frame.
