#Dbacks manager Torey Lovullo says he believes simply got away from Pirates pitcher.
He added that the team should know more about Iannetta's status on Saturday.
"He was up walking around. Everything was OK", Lovullo said. However, anytime a head trauma is involved, with batter is hit in that area, no one is comfortable until a full diagnosis has been made, so the team is using all precautions possible to make sure Iannetta is fine.
Diamondbacks: LHP Patrick Corbin (2-4, 3.89 ERA), coming off a rough outing in Colorado, gets the start for Arizona and RHP Tyler Glasnow (1-2, 6.33) goes for the Pirates in the second game of the series Friday night. He was able to walk off the field with help, holding a cloth to his nose.
On the 95th pitch of the night, Polanco finally broke it open for the Pirates, hitting the ball to nearly the same spot, just fair, for a home run. Arizona right-hander Tom Wilhelmsen hit Pirates catcher Chris Stewart in the right leg with two outs in the ninth inning.
Lovullo when asked following the game if the pitch that had hit Iannetta was intentional said that he stands by his thought that the pitch just got away from the Pittsburgh pitcher and was not intentional.
After quality starts in his last three appearances, Glasnow (1-3) gave up a career-high seven runs in 2 ⁄3 innings.
