Will the needs of the big league roster impact Eldridge's timeline?
"I'm not really sure about that," Melvin said. "He's going to have to perform to get here. That's something [president of baseball operations] Buster [Posey] has stated. If you perform well, then you've got an opportunity to get to the big leagues."
While the Giants view Eldridge as their first baseman of the future, the organization wants to make sure he's fully developed before giving him a chance to hold down the spot in the Majors.
"He's young, and he's super talented," vice president of player development Randy Winn said last month. "Big, strong. He's got some power. I think he's going to surprise some people with his hitability. He's got a really short swing. I just want him to continue to improve in all facets of the game.
"A lot of the game is kind of the mental side as well. How do you deal with failure? How do you hit in certain situations? How do you hit if somebody is pitching around you? How do you hit when you're not feeling great? Those are all things he's got to learn, but you can only learn that with more reps. And then obviously, becoming a complete player -- fielding, baserunning -- as well."
