Jon Gray has won his last four starts, allowing seven earned runs in 24 2/3 innings. That includes wins at home against the Dodgers and the Padres, and wins at San Francisco and Arizona, where he allowed one earned run in six innings. He has given up two home runs in his last seven starts -- one at Coors Field in 24 2/3 innings.
Ray is 1-5 his last seven starts, including a loss and a no-decision against the Rockies. He has allowed seven earned runs in 10 2/3 innings of those two games against the Rockies.
Gray won't mind missing David Peralta, who is on Arizona's Injured List. He is a career .478 hitter against the Rockies right-hander. Gray, however, will have to deal with Ketel Marte, who has hit .533 against him.
The Rockies Big 2 -- Nolan Arenado and Charlie Blackmon -- have had big nights against Ray. Blackmon, even though he is a left-handed hitter, has hit .452 with five home runs and 12 RBI against Ray. Arenado has hit .359 with three home runs and nine RBI.
