His right hand was smacked minutes earlier by a 94 mph fastball, but Rhys Hoskins told the Phillies doctor on Thursday night that he had trouble determining if he felt any pain. The adrenaline, Hoskins said, was pumping through after he watched Bryce Harper’s dramatic walk-off grand slam. A real test would have to wait.

A day later, Hoskins felt fine but there was enough concern to keep him out of Friday night’s lineup as a precaution. X-rays came back negative, manager Gabe Kapler said. Hoskins came out with just a contusion.

“I woke up today thinking it was going to be a lot worse than it was,” Hoskins said. “It’s always good progress when you do it.”

Hoskins tested his hand Friday afternoon with batting practice and told Kapler that he would be available to pinch-hit if needed, but instead he entered the game in the ninth inning as a defensive replacement. The hand was sore, but not enough to cause concern. Kapler said he expects to start Hoskins on Saturday.

“As soon as Rhys is ready to be back in the lineup, which we assume to be tomorrow, he’ll be back in there,” Kapler said Friday.

Hoskins was hit by Pedro Strop’s fastball in Thursday’s ninth inning to load the bases for Harper. He was on first base as Harper finished the game and started sprinting toward him.

“I looked up and I was jumping up and I started to jog and as I was turning second base I looked to see where he was at and what kind of reaction he was having,” Hoskins said. “And he was like halfway to second base and I was just touching second base. I was like, ‘I gotta go.’”

Tatis likely out for the season

The Phillies will miss Padres rookie Fernando Tatis Jr. this weekend as he was placed on the injured list before Friday’s series opener and could miss the rest of the season.

Tatis, who injured his back on a swing, is batting .317 this season with a .969 OPS. The 20-year-old shortstop was a spark at the top of San Diego’s lineup. The Padres also placed infielder Ian Kinsler on the injured list with a herniated cervical disc.

“Most likely, he’s done for the remainder of the season,” Padres manager Andy Green said of Tatis. “Disappointing, obviously. We’re going to do what we can to take care of him as a young guy in the big leagues who we expect to be a huge part of what we do going forward. It’s been really tough for him over the last couple of days to swallow this and for us, it’s a tough blow.”
