Photos from the Met Caravan in New York this week revealed potential number-switching for 2004. Jae Seo arrived at Grand Central wearing No. 38 and Braden Looper in No. 40. This represents a bit of a switch — Seo actually made his Met/MLB debut in No. 38 back in 2002 but that number was subsequently issued to Pat Strange, who wore it last year as well as Seo took No. 40.
Looper in the meantime appeared earlier this month at the Met Minicamp in No. 46, but perhaps due to our warnings below, thought better of it. (Thanks to Phillip for the tip!)
