Justus Sheffield needed to take a step back to take a step forward.
And that last step comes Friday night, when the left-hander is scheduled to take the mound for the Seattle Mariners when they play host to the Toronto Blue Jays in the opener of a three-game series.
Sheffield (0-0, 6.00 ERA), the centerpiece to the offseason trade in which the Mariners sent James Paxton to the New York Yankees, will be making his first major league start. He made one relief appearance April 26 for Seattle, allowing two runs on two hits and four walks over three innings. He was optioned back to Triple-A Tacoma the next day.
