The Rockies have designated pitcher Josh Sullivan for assignment, Troy Renck of the Denver Post reports. The move allows the club to add their Thursday night starter, Chad Bettis, to the 40-man roster.
Sullivan, 29, hasn't appeared in an MLB game in his career. The right-hander owns a 4.33 ERA in 363 1/3 career minor league innings, but hasn't been effective in a limited taste of Triple-A this year, posting a 13.50 ERA in 3 1/3 innings pitched.
Bettis, also a righty, jumps directly from Double-A into the Rockies' major league rotation. In 63 innings for the Tulsa Drillers this year, the 24-year-old has a 3.71 ERA with 9.8 K/9 and 2.4 BB/9.
