Robinson (shoulder) signed a minor-league contract with the Nationals on Friday, MLB.com's William Ladson reports. The deal doesn't include an invite to MLB spring training, which is likely a byproduct of Robinson being sidelined for all of the past season following shoulder surgery. Prior to suffering that setback, Robinson had spent most of 2013 season with the Reds, functioning as a reserve outfielder for the big club. He'll need to show he's fully recovered from the shoulder procedure in the minors before he has a reasonable shot at earning a fourth or fifth outfielder job for a Nationals squad that isn't lacking in depth at that position.

Chris Cotillo of MLBDailyDish.com reports that Derrick Robinson will be sidelined 4-6 months after undergoing shoulder surgery Tuesday.

Derrick Robinson did not play Saturday due to ongoing left shoulder soreness. Robinson continues to be bother by an injury he originally suffered back on July 9 on a slide into home plate.

Robinson, 25, batted .268/.344/.325 with two homers, 23 stolen bases and a .668 OPS in 116 games with the Royals' Triple-A affiliate last season.

Robinson, who was signed to a minor league deal this offseason, is hitting a cool .346 (9-for-26) with four RBI this spring. He's an extreme longshot to crack the opening day roster however, and is slated to open the season in the outfield at Triple-A Louisville.
