• Last year, the Cubs used six different players at third base, with Luis Valbuena, Donnie Murphy and Cody Ransom getting the majority of at-bats.
"Between the three, they made a pretty good, solid one," Renteria said of the trio, which combined for 30 home runs and 70 RBIs.
Ransom is now playing in Japan, and it's too early to say whether the Cubs will use a platoon at third between Valbuena and Murphy, Renteria said. Another option is Mike Olt, acquired last July from the Rangers in the Matt Garza deal.
"They all have an opportunity to come into camp and show us what they're capable of doing and as it plays out, we'll make a decision as to where we stand," Renteria said Monday.
• Cubs position players report on Tuesday with the first full-squad workout on Wednesday. Renteria will meet one-on-one with each player to go over goals and expectations this spring, starting Tuesday with the catchers.
• Edwin Jackson is sporting a new and elaborate tattoo on his left side this spring. It's a famous quote by Dr. Martin Luther King: "The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy."
It's one of many Jackson's many tattoos, which include footprints of both of his children, his No. 36, and "Est. 1983," which is when he was born.
"Your body is a story," Jackson said.
