"I'm pretty close," Yost said.
Five spots appear set. Second baseman Rickie Weeks, assuming he can work back from a swollen right hand, will hit leadoff. First baseman Prince Fielder and left fielder Ryan Braun are the Nos. 3-4 hitters. And Yost likes batting catcher Jason Kendall ninth, behind the pitcher in the No. 8 hole.
That leaves four slots unsettled. When center fielder Mike Cameron returns in late April from a 25-game suspension, he will bat second, but for now, Yost is trying to decide whether he likes shortstop J.J. Hardy there, or a center-field fill-in like Tony Gwynn Jr. Whoever is not used in the two-hole will likely hit seventh.
"On-base is going to be a really, really big component" in selecting a two-hole hitter, Yost said. "I want our best on-base percentage guys up for our boppers, before we get to Prince Fielder, Ryan Braun, Billy Hall and Corey Hart. ... I'm still pondering that two-spot, right now. It would probably be a moot deal if Cameron didn't have 25 games, because I really like him there. I like the fastballs he gets, in front of Prince Fielder and Ryan Braun."
The other spots up for grabs are the Nos. 5 and 6 slots. Third baseman Hall hit fifth on Friday against the Padres and right fielder Hart hit sixth, but Hart excelled in the five-hole last season (.319 average in 119 at-bats).
"Billy has had a really nice spring offensively, for me, and for Corey, it's been a bit of a struggle," Yost said. "But when Corey gets hot, look out."
