SATURDAY, 12:47pm: MLB.com's Jenifer Langosch reports that Bass has cleared waivers and accepted an assignment to Triple-A.
MONDAY, 3:03pm: The Pirates designated Brian Bass for assignment, according to Rob Biertempfel of the Pittsburgh Tribune-Review (via Twitter). The right-hander is out of options, so he'll be exposed to other clubs, but the Pirates wanted to make room for Ross Ohlendorf.
Bass, 28, allowed nine hits and eight walks in 6.1 innings for the Pirates this season for a 12.79 ERA. The Pirates signed Bass to a minor league deal in January, a month after the Orioles non-tendered him. Bass appeared in 48 games for the Orioles last year, logging 86.1 innings. He allowed 106 hits a year ago with 5.6 K/9 and 4.6 BB/9 so it wasn't a surprise when the Orioles declined to offer Bass a contract.
Within ten days we'll see Bass traded, released or, if he clears waivers, assigned to the minor leagues. Bass has been just part of the problem for a Pirates pitching staff that ranks last in the National League in runs allowed (195) and earned runs allowed (179).
