The Giants have designated left-hander Alex Hinshaw for assignment, according to Andrew Baggarly of the San Jose Mercury News (via Twitter). The move was made to make room on the 40-man roster for Mark DeRosa, who was activated from the 60-day disabled list.
Hinshaw, a 15th-round pick of the Giants out of San Diego State in 2005, made his big league debut in 2008 and last appeared in the Majors in 2009. In 57 career appearances, he has a 4.53 ERA, 9.7 K/9 and 7.1 BB/9. That's a terrific strikeout rate. Now, if only he could get his control in check …
Hinshaw has spent 2011 with Triple-A Fresno and Double-A Richmond.
