ST. LOUIS – Diamondbacks lefty Robbie Ray continues to make encouraging progress after taking a line drive off the head on Friday night, manager Torey Lovullo said.

Though Ray did show concussion symptoms – he was placed on the seven-day concussion disabled list on Saturday – Lovullo said Ray tested well in terms of cognition and balance, and he got through the first night after the injury without incident.

“He came into the clubhouse (on Saturday) and he looked really good,” Lovullo said. “Obviously, the wound was repaired with a couple of staples in his head. He just said he felt a little bit sore. Everything is trending toward a very positive outcome. We’re very thankful for that.”

Ray was struck on the left side of his head by a 108 mph line drive off the bat of the Cardinals’ Luke Voit in the second inning. CT scans did not reveal a fracture, Lovullo said, and Ray needed only to be treated for the cut on his head.

Lovullo said Ray’s wife, Taylor, caught a flight to St. Louis late Friday night and was with her husband overnight, following instructions provided by the club’s medical staff to make sure Ray’s condition remained stable.

“He had a really restful night, according to what he said today when I talked to him,” Lovullo said. “He ate last night, he slept well, just some general soreness as we can all expect, and then he got up and ate again. He felt very, very good.”

Taking Ray’s immediate place on the roster was right-hander Silvino Bracho, who gives the Diamondbacks a fresh bullpen arm after three relievers combined to cover 6 1/3 innings on Friday night.

As for what the club will do with the rotation, that’s not entirely clear, though Lovullo did suggest the team might not need another starter until next weekend in San Francisco.

With Monday’s off day, the other four pitchers can move up a day and still pitch on normal rest. Under those circumstances, the Diamondbacks could wait until Saturday, which would be the first day Ray is eligible to return from the DL.

“I think it’s too early to predict that,” Lovullo said, when asked if the club could arrange its rotation in hopes of having Ray start Saturday. “Anything is possible in this game, I know that, but we want to wait as long as we can before we announce those decisions moving forward.”

Ray had come and gone before reporters were given access to the clubhouse on Saturday, but he posted a statement on Twitter later in the afternoon.

“I wanted to take a minute to thank everyone for all the well wishes and prayers – your support has meant so much to my wife and me,” he wrote. “I am still recovering, but feeling much better already.”

Descalso makes ‘amazing play’ on Ray liner

Moments after Robbie Ray was struck on the head by a line drive, manager Torey Lovullo rushed from the dugout toward the mound. On the way, he noticed out of the corner of his eye that third baseman Daniel Descalso was running in a different direction.

“I was confused as to why,” Lovullo said Saturday. “Now I understand why.”

It turned out that Descalso was in pursuit of the ball, which caromed off Ray’s head and into foul territory, where Descalso made a diving catch to record an out on the Cardinals’ hitter, Luke Voit.

“The first thing I remember anybody telling me was (umpire) Greg Gibson telling me, ‘Just so you know, the batter is out. Daniel Descalso made the play.’ … It was an amazing play.”

Said Descalso: “Everything happened so fast. I didn’t realize it hit him in the head. I just went and tried to catch the ball.”

Short hop

Right-hander Randall Delgado’s throwing program isn’t scheduled to begin until Monday, according to Lovullo, who said he mistakenly told reporters on Friday that it would begin Saturday.
