"Heading back to SF and AT&T Park tonight! I’m so proud of Dan for working his butt off after his injury! He’s back ?"
Runzler, who last pitched for the Giants in 2011 is set to make his return from a series of injuries which forced him to work through a handful of minor league assignments this year.
The Revrun struggled at times, posting a 6.00 ERA between Single-A San Jose and AAA Fresno in a combined 30+ innings as he built up strength in attempts to return to the big boys.
Runzler holds a career 4.06 MLB ERA in 68.2 innings, his best season coming in 2010 when the lefty posted a 3.03 ERA in 32.2 innings.
