Michael Pineda was suspended for the past ten games following being ejected from a start against the Red Sox for having a foreign substance on his neck. It was the second such instance in two starts against Boston.
Though Pineda's suspension time has drawn to a close, he will now be placed on the disabled list by the New York Yankees. While pitching a simulated game during his suspension, Pineda suffered an injury to the lateral muscle on the inside of his throwing arm. It is a non-structural injury, but it will keep him on the shelf for the better part of a month.
Following two seasons fraught with injuries that left him without making a single start in the majors or minors from 2012 to 2013, Pineda was off to a good start this year, and seemed to be picking up where he left off with Seattle in 2011. Through four starts, he has pitched 19.2 innings, including the abbreviated start against Boston, with a 1.83 ERA. And though he hasn't been striking out a terrible amount of batters (6/82 K/9), he has effectively limited walks (1.37 BB/9).
Pineda was traded to New York following the 2011 season for catcher Jesus Montero, a trade that to this point has not worked out for either team. Though Pineda has been absent with injuries the past two years, Montero has returned negative value to the Mariners, to the tune of -0.8 Wins Above Replacement. He is currently in AAA Tacoma, hitting .264/.337/.560.
