The Mets purchased the contract of Marlon Anderson from their Triple-A New Orleans affiliate for tonight’s game. They signed him to a minor-league deal shortly after the Dodgers released him last Wednesday. Good news for a really good guy. It was probably the right move for the Dodgers to let him go, but he’ll be missed in their clubhouse. The bad news is that to make room for Marlon, the Mets optioned David Newhan, the former Pepperdine standout who lives in Yorba Linda, just in time for them to play a game in his hometown. This can be a cruel business sometimes, especially for David’s dad, Ross, a Hall of Fame baseball writer who I’m sure was looking forward to spending some quality time with him
