Giants reliever Jeremy Affeldt suffered a strained left groin during a relief appearance Saturday night against the Diamondbacks and has now been placed on the disabled list according to Henry Schulman of the San Francisco Chronicle. Jean Machi was recalled from Triple-A Fresno in a corresponding 25-man roster move to provide middle relief depth.
Affeldt has registered a relatively underwhelming 3.51 ERA, 1.26 WHIP and 5.7 K/9 in 33 1/3 innings this year out of the Giants ‘pen. He had a 2.73 ERA and 8.0 K/9 in 237 1/3 frames between 2009 and 2012.
The 34-year-old left-hander spent three weeks on the disabled list earlier this season with an oblique strain. He is likely to miss at least six weeks this time around, writes CSNBayArea.com’s Andrew Baggarly.
