Four of the Pirates' top prospects expected to be Marauders

Four of the Pittsburgh Pirates' top-20 prospects are expected to be on the Marauders' roster, according to this story on MLB.com.
Pitchers Jameson Taillon and Gerritt Cole, the team's No. 1 and 2 prospects, respecitvely, are expected to front the starting rotation. Pitcher Colton Cain (17th) and first baseman Alex Dickerson (14th) are also slated to start the year in Bradenton.
Taillon, 20, was the Pirates' first pick in 2010. He went 2-3 with a 3.98 ERA in 23 starts last season with the Pirates' low Single-A team in West Virginia.
The Pirates made Cole, 21, the first overall pick of last year's draft after his three seasons at UCLA. Cole was a first-round pick of the New York Yankees in 2008, but he didn't sign.
Cain, 21, was the Pirates' eighth-round pick in '09. He went 6-8 with a 3.64 ERA last year in West Virginia and is 7-10 with a 3.96 ERA in 39 professional games and 32 starts.
Dickerson, 21, was picked by the Pirates last year in the third round, and batted .313 in 41 games last year with the Pirates' New York-Penn League team in State College.
Dickerson was orginally drafted by the Washington Nationals in the 48th round in '08.
The story also says that Robbie Grossman (8th), named the Pirates' Minor League Player of the Year last year while with the Marauders, and second baseman Jarek Cunningham (20th) will begin the year with Double-A Altoona.
The entire Marauders roster will be unveiled Tuesday morning at Pirate City.
