Unless the Yankees acquire a big impact bat through trade, it seems like they will shore up their bullpen and rotation in order to compete in a division that seems to be getting more and more competitive with each passing day.
The Yankees might go all in on pitching in order to compete with the tough lineups in the AL East.
Now that Victor Martinez, Pablo Sandoval, and Hanley Ramirez have found their homes, it has been really difficult for clubs to find big time impact bats on the market, and some have found themselves hitting the trade market instead. As bad as the Yankees offense was last year, there isn't exactly a "savior" who they can throw money at, so perhaps they will look to improve their bullpen and pitching staff even more in hopes of fighting off the Red Sox and Blue Jays' additions on offense.
The bullpen currently sport the newly-signed Andrew Miller, Dellin Betances (who was completely ridiculous last year), lefty trade acquisition Justin Wilson, and holdovers Adam Warren, Shawn Kelley, and Esmil Rogers. As I'm writing this, the Yankees are still considering bringing back David Robertson as well which would create a scary trio at the end of games. Combine that with someone like 2014 top draft pick Jacob Lindgren, and a few other young bullpen arms the Yankees have coming up, and the bullpen can not only shorten games, but combat big time hitters in the AL East. They may not be able to get a lot of runs across the board, so a one-run lead going into the sixth or seventh inning may feel like a win with all those arms coming in.
