The Phillies will give the ball to right-hander Jonathan Pettibone in the series opener, the 22-year-old rookie will make his Major League debut as he takes the turn of the injured John Lannan.

In two starts at AAA this season, Pettibone was 0-1 with a 9.64 ERA.  However, he had an outstanding 2012, going 13-8 with a 3.10 ERA while splitting the year between AA and AAA.  In 159.2 innings last season, he allowed just nine home runs.  Pettibone was a third-round draft pick of the Phillies in 2008.

The Pirates will give the ball to veteran right-hander A.J. Burnett, who has thrown the ball extremely well here in 2013 despite a 1-2 record.  In 24 innings, he has allowed just 17 hits and 8 walks while striking out 35 batters.  His ERA is 2.63.
