According to all the usual suspect beat writers and the Phillies, LHP Raul Valdes has been optioned to Triple-A Lehigh Valley and RHP B.J. Rosenberg has been called to take his place. Valdes was at best mediocre in 2013 and at worst completely ineffective, with a 7.65 ERA and a 1.55 WHIP, allowing 10.8 H/9 IP.
Rosenberg, 27, has been mildly effective as a starter this year for the IronPigs, going 1-3 with a 4.30 ERA in seven starts. As Matt Provence points out, Rosenberg was sharp in his most recent start, picking up the win after seven scoreless innings pitched on 5/12 against Durham.
