Gray worked a perfect inning in his debut for the Texas Rangers on Thursday night, getting a groundout on his first pitch in the majors and ending the 6-1 win over the Pittsburgh Pirates with a strikeout of Konnor Griffin, the highly touted shortstop playing the day before his 20th birthday. “Getting my first career strikeout on him is pretty cool.” The Rangers promoted Gray from Triple-A Round Rock earlier Thursday when placing left-handed reliever Robert Garcia on the 15-day injured list because of left shoulder inflammation after he hadn't pitched in a week.
