Alonso exits after being hit by Upton's helmet

DENVER -- Padres first baseman Yonder Alonso left Saturday's 7-5 victory over the Rockies in the eighth inning for precautionary reasons after he was hit in the head with a helmet that Justin Upton threw in frustration.

Upton, who was caught in a rundown for an out in the top of the inning, threw his helmet after returning to the dugout and it hit Alonso, who was sitting on a bench behind him, on the right side of his head.

Alonso then fell to the ground in pain.

"We're out there competing and that's a big point in the game and I made a big mistake," Upton said afterwards. "I was pretty upset about it.

"It's childish. I've got to do better than that and not make that mistake again."

Alonso was attended to by team trainers and was later looked at by the Rockies' medical staff which deemed him not to have concussion-like symptoms.

The Padres said they will re-evaluate Alonso Sunday morning.

"I was just watching the game and felt something just hit me right across the head," Alonso said. "But it's part of the game. Guys get upset. I'm fine. Luckily, everything checked out well. We're going to move on."

Alonso was asked if he spoke with Upton after the incident.

"We discussed that," he said. "I don't think you guys [need to] know what was said. We talked about it, and it's all good."

Alonso was replaced in the bottom of the inning on defense by Derek Norris, who moved from catcher to first base. Austin Hedges then entered the game to catch.

The incident didn't sit well with Padres interim manager Pat Murphy.

"It happens. I don't approve of it. I don't think it's great. I think we can see what can happen. It's really unacceptable to do it around other people," Murphy said.

"Most of the time, showing that type of anger and that type of stuff is not healthy in my mind at all. I don't think it's a sincere form of handling a result. I don't see any place for it."
