LOS ANGELES -- At some point this year, D-backs first baseman Jake Lamb might see some time at third base, but it will not happen for a while, according to manager Torey Lovullo.

Lamb had been exclusively a third baseman, but when the D-backs dealt Paul Goldschmidt to the Cardinals in the offseason, Lamb was shifted to first. Because the position was new to him, Lamb took all of his Spring Training game reps at first.

If Lamb played some third, it would allow Lovullo to get Christian Walker’s bat in the lineup more often at first.

“I think we’re going to put that idea on hold where we’ll move him across the diamond,” Lovullo said. “We have definitely discussed it. It has come up. And yes, it would be nice to get both of those guys in there. But for the short-term time being, I think we’re going to stand pat at first base. Because we didn’t get a chance to do it in Spring Training, I want to work at it instead of just throwing him in there. I want to make sure he’s prepared before we throw him in there.”

Lamb was going to get some game action at third base this spring, Lovullo said, but it was supposed to be right around the time that Lamb had to miss a few days due to back tightness, so the plan was scrapped.

Catching combo

It looks like Zack Greinke will throw to John Ryan Murphy for the right-hander's first few starts, while Lovullo got Alex Avila in the lineup at catcher Friday night against the Dodgers with Robbie Ray on the mound.

It’s likely that Avila will start again Saturday, which means Carson Kelly will likely get his first start behind the plate Sunday with Luke Weaver on the mound.

Weaver and Kelly have a comfort level because they played together in St. Louis and both came over in the Goldschmidt trade.

“I want to put Carson in the best situation possible for potentially his first start,” Lovullo said. “I’m thinking long and hard of having him pair up with Luke. I know they know one another, they already feel comfortable with one another. That’s something I’m definitely thinking about.”
