Double-A prospect Joseph returns from DL red-hot

When Tommy Joseph went on the disabled list after suffering another head injury and potential concussion on April 25, he was in the midst of a tear. After going 0-for-4 in his first game back on Saturday, he got right back to destroying Eastern League pitching on Sunday.

Joseph, the Phillies' No. 16 prospect went 4-for-5 with a home run and three RBIs for Double-A Reading. Before he went on the DL, Joseph had reeled off an eight-game hitting streak and had homered in three of his last four games. He now has four homers and 12 RBIs in his last six games.

There is reason for concern about Joseph's health, however. The 22-year-old backstop played in just 36 games in 2013 because of concussion-related issues. So when he took a foul tip off of his head on April 25 and reported feeling uncomfortable, the Phillies immediately put him on the disabled list.

When healthy, the 2009 second-round pick of the San Francisco Giants, who came to the Phillies in the 2012 Trade Deadline deal for Hunter Pence, has shown serious home-run pop. He had a career high 22 homers in 2011, while playing for San Jose in the California League.
