Here's a fun fact: The Giants' Brandon Belt has as many home runs this spring as he did all of last season.
Yes, it's the Cactus League, which tends to make muscle men out of lean, mean doubles-hitting matchines. Yes, it's spring training, where any stat of any note comes with a disclaimer. But for a player just entering his prime who has yet to meet his power potential but did manage to compile a .494 slugging percentage over the final two months last year, it's encouraging.
It could, in fact, be nothing, so I should warn you not to overvaluate it and reach for Belt ahead of, say, Ike Davis or Eric Hosmer. But if it's part of your justification for targeting him with a late-round pick, you should know that I'm right there with you.
