"It's not a question of what we need to see on the field to make us buyers, it's what we see on the field that causes us not to be buyers," Alderson said. "The presumption here is that we're buyers, and it has been. Realistically, the next seven, eight, 10 games become important for us."
The Mets have a well-documented need for bullpen help, as they entered Saturday's game against the Dodgers at Citi Field with a 4.95 bullpen ERA, the worst mark in the NL. But holes in the rotation are now equally as glaring, and Alderson is unsure of how he will fill them.
He has internal options -- Jeremy Hefner, Matt Harvey and Jeurys Familia -- and does not expect the injury to Santana to alter his Trade Deadline strategy.
"This, in and of itself, doesn't change our approach," Alderson said. "I think the results on the field will dictate that. This will have an impact on us every five days, no question about that."
