It should be no surprise that the Pittsburgh Pirates are unsatisfied with their current first base situation. They brought in Travis Ishikawa in a waiver claim earlier this month, despite the fact that he is a left-handed hitting first baseman, just like Pedro Alvarez. And the reason they would be unsatisfied with first base is because Alvarez has been horrible defensively, while also seeing his offense slump.
So the latest news from Jeff Passan, quoting one GM saying that the Pirates are offering Alvarez to everyone, isn't a shocker.

Alvarez is making $5.75 M this year, and he doesn't have much trade value, since he has been replacement level the last two seasons.
