Chris Johnson hit a two-run homer Saturday in the Astros' 3-1 win over the Nationals. Johnson was one of the stars of the spring two years ago, when he hit eight homers and drove in 22 runs in 62 at-bats. He'll probably need to do something similar this month to end up as Houston's starting third baseman. He's behind Jimmy Paredes at the moment and he's facing competition from Brett Wallace and Matt Downs as well.
