 On April 10 , 2014 , Yankees pitcher Michael Pineda was believed to have been using pine tar in a Yankee @-@ Red Sox game at Yankee Stadium . This was never brought to the umpires attention , therefore it was never tested and no actions were taken . On April 23 , 2014 , at a Yankee Red Sox game in Fenway Park , John Farrell noticed that Pineda was using pine tar again . Farrell walked to the home plate umpire and got Pineda ejected from the game in the 2nd inning .
