The starting rotation could be the Achilles Heel that sidetracks the youth movement. On Monday in West Palm, Michael Pineda recorded only five outs because he threw 33 pitches during the second inning of the Yankees' 9-3 exhibition victory over the Nationals. The day before, Luis Severino's command was off and he gave up three runs on six hits in 3.1 innings. If the 23-year-old righty keeps pitching like that, he's going to start the season at Triple-A Scranton instead of the Bronx. Sabathia, who is coming off a knee cleanout procedure during the offseason, has an ERA of 9.45 this spring. http://www.nydailynews.com/sports/baseball/yankees/yankees-pitchers-continue-quell-rotation-concerns-article-1.3003716
