NEW YORK — New York Mets ace Jacob deGrom was pulled after six scoreless innings Friday night with right flexor tendonitis, a troubling diagnosis for the two-time NL Cy Young Award winner amid a historically dominant season.

DeGrom had a no-hitter until Wil Myers beat the shift with a weak grounder in the fifth. DeGrom’s 0.56 ERA is the lowest ever by a pitcher through 10 starts, just ahead of Juan Marichal’s 0.59 in 1966.
