Look Who's Playing First Base — Matt Christopher

When the Checkmates needed a new first baseman, Mike Hagin's new friend, Yuri, seemed like a logical choice. But when Yuri started flubbing plays and the team's star player threatened to quit as a result, Mike was not sure Yuri was such a good choice after all -- for a teammate or for a friend. The story of how Mike helps Yuri develop as a player, and of how Yuri helps Mike develop as a friend, is an absorbing and exciting one for all sports fans.
