The Oakland A's placed left-handed pitcher Brett Anderson on the 10-day disabled list with a strained left forearm, the club announced Tuesday. To take his spot on the roster, the A's recalled right-handed pitcher Ryan Dull from Triple-A Nashville.
Anderson started for the A's last night in Houston and allowed five runs on seven hits in 2.2 innings for the loss after allowing just two runs in 26.2 innings over his previous four starts. This is his second stint on the DL this year as he was out from May 19 to July 7 with a strained left shoulder. Anderson is 3-4 with a 4.02 ERA in 13 starts overall with Oakland. 
Dull joins the A's for the fifth time this year and has a 5.89 ERA and .296 opponents batting average in 21 relief appearances. He was most recently with the club from July 30 to Aug. 6 and made one appearance during that stint, retiring the only batter he faced on July 30 against Toronto. The 28-year-old right-hander was 3-2 with a save and a 3.76 ERA and .280 opponents batting average in 22 relief appearances with Nashville. Dull pitched five times following his Aug. 7 option and allowed five runs on 10 hits in 7.0 innings.
The A's have now used the disabled list 25 times, including 11 times for starting pitchers.
