Today, the Oakland A’s optioned right-handed pitcher Andrew Carignan to Triple-A Sacramento. The move was made to clear a roster spot for left-handed pitcher Travis Blackley, who was claimed off waivers from the San Francisco Giants yesterday.
Carignan was recalled from the Sacramento RiverCats last Friday for his second stint with the A’s. He appeared in two games, allowing two runs on two hits and three walks in 2.0 innings of work . Carignan is 1-1 with a 7.11 ERA in seven appearances with Oakland and has issued eight walks in 6.1 innings.
Blackley began the season at Triple-A Fresno and was 3-0 with a save and a 0.39 ERA in four games, three of them starts. He was called up by the Giants on May 1, where he posted a 9.00 ERA and .333 opponents batting average in four relief appearances with San Francisco before he was designated for assignment on Sunday.
