KANSAS CITY, Mo. (AP) — Seattle Mariners star Felix Hernandez left in the seventh inning of Monday's game against the Kansas City Royals with an aching lower back.
After Hernandez made a pitch to Alex Gordon, Mariners manager Eric Wedge and a trainer rushed to the mound.
They had a brief conversation with Hernandez and he was replaced by Oliver Perez. The team announced the injury was a cramp in his lower back.
Hernandez, the 2010 American League Cy Young Award winner, struck out Mike Moustakas in the sixth for his 200th strikeout, the fifth consecutive season he has reached that mark.
He had thrown 105 pitches in 6 2/3 innings and Seattle was trailing 3-1.
