This per Baggs.
The Giants made the decision to keep Sanchez’s surgery quiet because at the time, they were negotiating with Juan Uribe to bring him back as a reserve. ... Well, you’d better believe that news of Sanchez’s surgery would’ve impacted the Uribe negotiations. Uribe’s agent would’ve known he had more leverage and might have squeezed more money out of the club, or in the least, drawn out negotiations that would’ve prevented Giants officials from wrapping it up and concentrating on other business. So the hush-hush on Sanchez worked to the team’s advantage.
Keeping the surgery quiet? No big deal. The Giants FO lying about the reasons why it was kept quiet and making Mole-man the patsy? Shitty at best.
