Five things to know about the Rays’ latest new catcher, Erik Kratz, who was acquired Thursday night from the Giants:
* He is 38 (and will turn 39 on June 15), which makes him old for any player, especially a catcher. The Rays have had only four older position players, Wade Boggs, Julio Franco, Fred McGriff and Jose Molina. Last year with Milwaukee Kratz became oldest player to make his postseason debut since Jose Morales in 1983 with the Dodgers, and to start in his postseason debut in more than 100 years, since Lave Cross did at 39 for the Philadelphia A’s in 1905.
