Corey Seager or Jimmy Rollins? That’s the question for Dodgers ... but why not both?

The new kid is quiet, smooth, steady, swinging with barely a sound, connecting with every bit of boom.

“I’m having a blast,” Corey Seager said.

The aging vet is a bundle of energy, bouncing and gritting and fighting to overcome a hand injury to reclaim the new kid’s spot.

“I just need a couple of games, a couple of at-bats, honestly,” Jimmy Rollins said. “It doesn’t take long.”

The new kid could be a Dodger for years. The aging vet will be a Dodger only for the next six weeks. The new kid represents the distant shine of the Dodgers future. The aging vet represents the angst-filled hope of the Dodgers present.

Corey Seager and Jimmy Rollins couldn’t be more different, but the Dodgers shortstops have been lumped together this fall in a three-word question that has become all the rage.

Who ya got?

Who do you think should be the starting shortstop for the Dodgers in the postseason?

Most fans think it should be Seager, and why not? In his first 11 games here, he looked like Cal Ripken Jr. and played like Derek Jeter, batting .432 with six doubles, seven RBIs and an OPS of 1.219.

In a recent count of a Los Angeles Times poll that drew more than 4,000 respondents, 3,131 (79%) thought Seager should be the starter, while 847 (21%) thought Rollins should start.

The 21-year-old kid has been so impressive, you’ll never believe who has become one of his biggest fans.

“Hey, he’s really good,” Rollins said. “Always smiling, nice strong legs, a good swing, I really like him.”

But lots of folks, including many of the veteran baseball people in and around the Dodgers dugout, still love Rollins.

Even though the 36-year-old veteran is hitting just .220 with a .634 OPS, he can still do the one thing that has occasionally befuddled Seager — make the routine play. Rollins still ranks eighth in baseball in fielding percentage with nine errors in 127 games at shortstop while Seager already has three errors in nine games at shortstop, including one misguided throw to third base in Tuesday’s game against the Colorado Rockies.

There are other fielding metrics that rank Rollins lower, but many Dodgers still see him as playoff fielding gold — a guy who fills the shortstop hole unflappably after 46 postseason games and one World Series ring. With Dodgers aces Clayton Kershaw and Zack Greinke requiring more solid fielding than dramatic hitting, and with third starter Brett Anderson leading all of baseball in ground balls induced at 66.7% (according to Fangraphs), Rollins’ glove is probably more valuable to them than Seager’s bat.

So, seriously, who ya got?

Instead of answering this question with his usual fist-pounding hyperbole, this columnist will answer with another question.

Why not both?

Here’s guessing that if Rollins returns to the lineup within a week as expected, and if Seager continues to act like he belongs here, both guys will play in a rotation with third baseman Justin Turner in October. Sometimes Seager would play shortstop instead of Rollins. Sometimes he would play third alongside Rollins, with Turner, who’s batting just .188 since returning from a leg infection Aug. 13, taking a seat. Of course, if Howie Kendrick’s hamstring doesn’t heal as expected, Turner could play second base and all three guys would be on the field at the same time.

Think about it. The Dodgers’ new management team has been shifting around players like Lego pieces all season long, and mostly with success, so why would they stop now?

Believers in lineup continuity and many longtime Dodgers fans would hate the daily changes. Remember, this is an organization that once played the same four infielders for 8 1/2 years, and now they would be juggling infielders during the same October week? But after a 27-year World Series drought, new ideas should be tolerated, if not welcomed.

When Manager Don Mattingly was asked Tuesday whether Rollins was guaranteed a spot when he returns to the lineup, he was noncommittal. Seager joined the team after Aug. 31 but would be eligible for the postseason because of an often-used injury loophole.

“Well, we’ll see,” he said. “We’ve used Corey, and we’ll continue to put our best lineup out there. . . . Everything’s always evolving.”

Rollins took batting practice Tuesday for the first time since leaving the lineup nine days earlier. He said swinging felt good but pain occurred when he threw, so he wasn’t yet ready to return to the lineup. He entered the game as a pinch-runner in the seventh inning and scored the tying run.

“The way it’s progressing, I’m going to be good soon,” Rollins said.

Rollins should have his job back whenever he’s ready. But Seager will also be out there somewhere. On a field that hasn’t staged a Dodgers championship celebration in forever, there should be more than enough room for everyone.
