Dodgers sign Justin Turner as a little second baseman insurance

It’s three days until pitchers and catchers report to spring training for the Dodgers, and do you know where their starting second baseman is?

They’re going in big time with Cuba’s untested Alex Guerrero, a shortstop who’s never played a lick of professional baseball. Of course, sign him to a four-year, $28-million deal, and maybe it should seem you’re going all in.

But if Guerrero fails either defensively or offensively, the truth is the Dodgers have no viable backup plan.

Unless you’re all excited about the prospect of Dee Gordon’s conversion or the comeback of Chone Figgins or the flier on Brendan Harris.

On Wednesday, however, they took a small step in the right direction, signing Justin Turner to a minor-league contract with an invitation to spring training.

Turner, 29, could at least add some workable alternative and another decent possibility to fall from the Figgins-Gordon-Harris tree.

Turner hit .280 in 214 plate appearances for the Mets last season. The Mets non-tendered him so he was out there and available. He’s a utility infielder who has spent most of his time at second.

He’s batted .260/.323/.385 for his four-year career, not great maybe, but in an otherwise stacked Dodgers lineup, something they can get by with if they have to wait on Guerrero.
