It's just a spring training game, and Milledge is the anointed lead-off man once the season starts, but today's line-up has Nick Johnson leading off.
(He was also DH-ing, which when Nick inevitably goes to Oakland in his latter years is where I expect to see him make headlines when he leads the A's to the playoffs with a healthy, MVP-caliber season at some point when he's maybe 34 or 35 years old. Mark it down. You heard it here first.)
As I've discussed before, Nick is damn near the ideal lead-off man. At the top of the line-up, first and foremost, you want one of your very best hitters. Batting lead-off gets you about 70-80 more plate appearances over the course of the season compared to hitting in the middle of the order. That's significant if you're trading Cristian Guzman for Nick Johnson.
Second, you want a high on-base guy. The most important thing is leading off an inning is to just not make an out. Run expectancy with no outs and no one on is 0.52 runs. Putting a guy on first base almost doubles that to 0.90. Meanwhile, no outs and a runner on second base only raises RE to 1.15. These numbers show you not only the huge value of getting that first hit, but also the relative unimportance of stealing second base. Furthermore, stealing in front of a big power hitter like Adam Dunn is even less smart, since he's always one swing from knocking himself in. The key is to just have a guy who isn't a bad baserunner. You want enough speed to avoid clogging the bases, and you want someone who isn't going to run into outs. But stealing a lot of bases isn't a prerequisite.
Of course power is always good, even in the lead-off spot, and getting those extra ABs for guys who have some pop is desirable, but you don't want your biggest power hitters there for obvious reasons.
Put all that together, and Nick's by far the best option.
One other thing. Since my strangely controversial post last week praising Nick Johnson's excellent spring, his line is up to .268 / .400 / .537. Only eight players in the whole league put up numbers to match those last season: Albert Pujols, Hanley Ramirez, Matt Holliday, Milton Bradley, Chipper Jones, Manny Ramirez, Lance Berkman, and Mark Teixeira. Extend his spring numbers over a full 700 PA season, and he'd have 46 homers and 136 RBI.
That's not called struggling. That's called a great spring training.
