Tampa Bay Rays rookie outfielder Desmond Jennings homered, singled twice, knocked in four runs and even stole a base in a mammoth performance Thursday. Jennings, hitting .500 with seven RBIs and four steals in his first week with the club, is fantasy's most added player in the past week, up to 79.7 percent owned. It's all worth it.

San Diego Padres rookie first baseman/shortstop Jesus Guzman homered, stole a base and raised his batting average to .329 on Thursday. Guzman, a 27-year-old minor league journeyman, is finally getting his shot in the big leagues and is making the most of it. He's not standard-league material yet, but if you need a middle infielder with pop, he's a sleeper.

Kansas City Royals first baseman/designated hitter Billy Butler homered Thursday, the third consecutive day he did so against the Boston Red Sox. Butler's finally reached double-digit home runs on the season, and though that's still underwhelming for a corner infielder, perhaps he's finally turning all those doubles into home runs. He's still worth owning for the batting average and RBIs.
