The Washington Nationals will be without 3B Ryan Zimmerman for the next two weeks as they placed him on the DL with a hamstring injury. They called up top prospect Anthony Rendon, who will make his major league debut. Rendon is absolutely worth adding to your team in all formats, doesn't matter if you had Zimmerman or not. Zimmerman was off to a terrible start, hitting just .226, striking out 14 times in 15 games. Just 4 of his 15 hits were for extra bases.Rendon, born in 1990, is off to a nice start in the minors hitting .292 with 4 doubles and 2 home runs driving in 7 runs and scoring 8 times in 14 games. He brings to the Nationals a great batters eye, as made evident by his 14 walks and just 9 strike outs.Other options to consider are Josh Donaldson, Chris Johnson, Juan Francisco and Placido Polanco.
