[Oops! Ibañez's homer was in the 7th to tie it up. Werth's second homer of the night won it in the 9th. JAYSON!1! Woo-Hoo!]
Actually, it's not fair to say he finally came through because, yeah, he's only hitting .222 even after going 2 for 4 last night, and so has been in a hitting slump, obviously; but he's worked a lot of key walks (he has 13, which is ninth in the NL), and he's got 4 doubles already. His On Base Percentage is .362, which is better than it was last year.
(In baseball? You can "prove" anything with stats.)
Ibañez and Werth crushed all three homers as you can see in this video. Bonus: The Diamondbacks' batboy is a member of the AARP.
