Oakland Athletics make four roster moves with pitchers, add Australian native Jack O'Loughlin

The Oakland Athletics have selected the contract of Australian native Jack O'Loughlin and recalled fellow pitcher Tyler Ferguson from Triple-A Las Vegas on Saturday. The moves came after the A's placed right-handed pitcher Ross Stripling on the 15-day injured list with a strained right elbow and designated right-handed pitcher Brandon Bielak for assignment. The 24-year-old will be making his big league debut when he plays.
