What are his chances of becoming the closer for Arizona any time soon? Valverde has pitched in 11 innings, while Mantei has only pitched in 5 innings. But, Valverde still has not had a save opportunity this season. Im not really sure, but it looks to me like Mantei's job is pretty safe, at least for quite some time (probably until Mantei gets traded, if he ever does). Valverde is taking up a spot on my roster and there are other batters that would probably help me more at this point. But, the waivers are picked over, so he is my best choice for a closer without having to trade. I will make a trade for another closer soon, but I still am curious as to what will happen with Valverde.
