Over/under: Troy Tulowitzki's home runs

Troy Tulowitzki will once again be a popular preseason MVP selection, especially if you believe in the Rockies' chances in the wide-open NL West.

He's finished in the top-10 of the MVP voting each of the past three seasons and has won two consecutive Gold Gloves as well. The only question: Will he stay healthy?

He missed 19 games in 2011 and 40 games in 2010. When he's played, he's been productive, hitting for power and average. Over the past three seasons he's averaged 139 games and 30 home runs.

After hitting 30 home runs in 143 games last season, that seems like a pretty good barometer for his 2012 output. I'll set his over/under for home runs at 30.5.
