Worth noting

• The Bucs claimed right-hander Wirfin Obispo on waivers from the Braves on Sunday and optioned him to Triple-A Indianapolis. The 29-year-old Dominican led International League pitchers with 54 appearances last season and was 2-1 with a 4.66 ERA in 19 appearances this season with Triple-A Gwinnett.

Stolmy Pimentel (shoulder inflammation) is scheduled to take another turn at extended spring training Monday, this time for two innings. He did some flat-ground throwing Saturday and has avoided any setbacks.

• Manager Clint Hurdle's preference for having relief pitchers start innings -- and to generally refrain from any mid-inning pitching changes -- is reflected by the fact Pirates relievers have had to deal with only 48 inherited runners all season, which ranks 29th in the Majors. Only Colorado (45) has had fewer.
