BALTIMORE: The Indians’ first pick in the June draft, Clint Frazier made his professional debut in the Arizona rookie league Tuesday night by going deep in his first at-bat and delivering a bases-loaded triple in his next trip to the plate.

“It’s hard to have a better start to a pro career,” General Manager Chris Antonetti said. “It will be a great story to tell his grandchildren some day.”

That won’t be for a while, inasmuch as Frazier is 18. He was in the lineup at designated hitter rather than the outfield, because Tribe player development people want him to build up his arm.

DON’T RUSH HIM — Francisco Lindor is batting .307 at Carolina and handled major-league competition with aplomb in spring training. Does that mean he’s ready to make a step up to Double-A?

Maybe.

“He’s still only 19, so he’s young for the league he’s playing in now,” Antonetti said. “He still has things to learn.”

Defensively, Lindor has committed 15 errors in 69 games at shortstop, which is not an unusually high total for a talented Class-A infielder.

Added Indians manager Terry Francona, “He’s so mature, and not just his personality, but the way he plays the game.”

NIGHT OFF — Carlos Santana got his first night off since May 9, a span of 44 games.

“I thought this would be a good time for him to get a complete day,” Francona said. “Chicago has three left-handers going, so Carlos is going to play in at least three of the next four games.”
