ST. LOUIS — You could probably figure this out by looking at Corey Seager‘s recent stats at Triple-A Oklahoma City (he’s 10 for his last 13), but Yasmani Grandal confirmed it with his eyes Friday.

“It looks like he’s hitting BP,” the catcher said of Seager, the Dodgers’ 21-year-old shortstop of the future.

Seager went 6-for-6 Thursday, falling one hit short of tying a Pacific Coast League record and a triple shy of the cycle.

“I’m really impressed,” said Grandal, who batted behind Seager during his rehab assignment with the Dodgers’ Triple-A affiliate. “He’s got good hands too, made a couple plays up the middle. But I’m really impressed with the bat.”

Seager hit a ground-rule double in his sixth plate appearance at Smith’s Ballpark in Salt Lake City. The ball hopped over the right-field fence on a bounce. “I think the fence comes in to 315” feet, Grandal said. “It could’ve been a triple, easy.”

Grandal recounted their exchange when Seager returned to the dugout:

“I said, what did you need for the cycle?”

“A triple.”

“So you just missed it?”

“Yeah.”

“Oh, man.”

That’s certainly not hard to imagine coming from Seager, who is by all accounts a man of few words.

Dodgers manager Don Mattingly didn’t exactly back off his praise for Seager on Friday, either.

“To me you could throw the kid in the big leagues right now and he’d be fine,” Mattingly said, “but he’s going to hit his stretches where he struggles and really letting him go through the development part is the best way.”

Mattingly said it would not be fair to Seager to predict when he will reach the big leagues, though it became quite the pastime for Dodgers fans in the last 24 hours. (Seager was a trending topic in Los Angeles on Twitter at one point Thursday.)

We only know that for now, the Dodgers are content to let Seager get his work done in Oklahoma.

“All of us know he can play,” Mattingly said. “All of us know what this kid is capable of. Until the last four or five days he’d struggled there. Then all of a sudden he hits two homers, gets four hits, gets six hits and all of a sudden he’s figured it out. I don’t think it’s a true surprise. I don’t care if you’re in American Legion, (10-for-13) is hard to do. I don’t think there’s anything surprising about Corey, and just how good this kid is. He’s been given all the attention. Minor leagues … we got to see him in spring training and he was impressive in spring. It’s just a matter of, I think, making sure his development is complete. We go from there.”
