A high-school catcher with a tantalizing power bat (15 homers in 27 games in his senior year), the double-named Tommy Joseph was scooped up by the Giants in 2009. In addition to his terrific raw power, Joseph displays a very strong throwing arm and shows signs of excellent leadership and discipline on the field. While the catcher's position in San Francisco would seem to be locked up for the foreseeable future, the Giants are looking for cheap meidcal insurance as much as any team, especially after the ESPN highlight (lowlight?) injury suffered by Mr. Posey in 2011.

ToJo can also play a reasonable first base, and is athletic enough to learn third if necessary. He's still a bit away away from the big leagues, but he shows every sign of being well-equipped to get there in the not-too-distant future.
