The Reds have designated right-handers Josh Ravin and Kyle Lotzkar for assignment in order to make room on the 40-man roster for Johnny Cueto and Sean Marshall each of whom is returning from the 60-day disabled list according to assistant director of media relations Jamie Ramsey (on Twitter). Ravin 25 was the Reds' fifth-round pick out of high school back in 2006. The California native posted a 5.82 ERA with 8.5 K/9 and 6.7 BB/9 in 51 innings of relief between Double-A and Triple-A in the Cincinnati organization this season. Solid strikeout totals and troubling command have become the norm for Ravin as evidenced by his career 8.1 K/9 and 6.1 BB/9 in parts of eight minor league seasons.
