LOS ANGELES – The Los Angeles Dodgers announced that they have activated left-handed pitcher Hyun-Jin Ryu from the 10-day injured list and optioned right-handed pitcher Casey Sadler to Triple-A Oklahoma City.

The South Korea native is coming off one of best months of his career, in which he posted a 2-0 record with a 0.55 ERA (2 ER/32.2 IP) and 23 strikeouts in five July starts. He was awarded National League Pitcher of the Month for May after going 5-0 with a 0.59 ERA (3 ER/45.2 IP) and 26 strikeouts.
