BALTIMORE — The Mets open a three-game series here tonight with the Orioles still answering lingering questions about Johan Santana‘s health after former coach Rick Peterson said he heard Santana’s surgically repaired left knee is bothering him. Colleague Kevin Kernan writes that it’s high time Omar Minayasaves the Mets’ season by making a trade.

In the notes, this will be the Mets’ first visit to Camden Yards since 2001.
