Right-hander Peter Solomon, who made his only six major league appearances for the Houston Astros last season, was claimed off waivers Sunday by the Pittsburgh Pirates and optioned to Triple-A Indianapolis.

Solomon, 26, was designated for assignment by the Astros on Thursday. He was 1-0 with a 1.29 ERA in his six major league outings last season. In 23 appearances (18 starts) for Triple-A Sugar Land this season he was 8-6 with a 5.20 ERA.

Solomon had been ranked by mlb.com as the Astros’ No. 28 overall prospect.

To make room on the Pirates’ 40-man roster right-hander Colin Holderman (shoulder) was moved to the 60-day injured list.
