Starlin Castro continued to bask in his early-season glory Thursday, fielding questions before the Yankees’ late afternoon game with the Astros at the Stadium. He’s hitting .583 (7-for-12) with eight RBIs after going 2-for-4 with a home run, his second, in the Yankees’ 8-5 win. A fine day, even if his average did fall 42 points. No matter how dialed in you are, a .625 pace is tough to maintain.

He’s certainly one of the hottest players in baseball, but a former Yankees second baseman also is tearing it up. Robinson Cano had four home runs and seven RBIs in his first three games for the Mariners. He has a major league-leading 19-game hitting streak, dating to last season, and he’ll be here next weekend when the Mariners play a three-game series.

What would it have been like for Castro, he was asked, if Cano was the person he replaced instead of the below-average production of last season.

“I mean, I don’t really ask myself that question,’’ Castro said. “I don’t really know. I don’t really know if I came after him.’’

Cano left the Yankees after the 2013 season for a 10-year, $240-million deal with the Mariners.

“Everybody knows he’s a great player,’’ Castro said. “I talk to him when we play against him. He’s a really good guy and everybody wants to hit like him. He’s a really good person, a really good player. I think he’s the best.’’

If both remain hot, comparisons are apt to be made when the Mariners visit. “I don’t really listen about that,” Castro said. “Coming here, I just try and do my best.’’

Castro batted eighth in the first three games. The former Cub has no idea if he’ll be moved up in the order.

“No, I mean, I don’t know,’’ he said. “That’s one thing I can’t control. I’m not going to go in the manager’s office and say, ‘I want to hit this.’ In Chicago, I got in every way. First, second, third, fourth, seventh, fifth. It doesn’t matter. Anything that’s good for the team.’’
