According to Troy Renck of the Denver Post, the Rockies have designated RHP Felipe Paulino for assignment. 

Acquired in an offseason trade with the Houston Astros for infielder Clint Barmes, Felipe Paulino was initially looked at as a #5 starter for the Rockies. During Spring Training, however, the Rockies decided that Paulino's arsenal was better suited for the bullpen, where he could unload at 100% without having to be concerned with longevity.

After a passable start to April, the wheels came off quite readily as Paulino labored through May. While month-to-month, Paulino's BB9 (arguably his greatest liability) dropped from a 5.40 BB9 in April to a 2.84 BB9 in May, the rest of his performance wasn't enough for some mild improvement in the free-pass department. 

Possibly a victim of questionable management, Paulino simply wasn't able to get the job done when the Rockies needed him, taking the role of the goat in many walkoff losses. These losses clearly affected Paulino, as his performance seemed to get worse and worse as other teams celebrated at home plate. The first couple of miserable losses seemed to be of the "ball missed gloves and/or was blooped" variety, but many of the untimely walks made those bad luck balls that much more deadly.

In Paulino's stead, RHP Greg Reynolds will be promoted to the majors as a potential long reliever and a likely starter on Saturday, given a doubleheader knocking the rotation out of alignment. Reynolds was up in the majors earlier this season when Ubaldo Jimenez hit the DL, making 2 starts to the tune of a 3.27 ERA (4.64 FIP, 4.71 xFIP) over 11 innings.

Paulino posted a 7.36 ERA (5.09 FIP, 3.37 xFIP) over 18 outings with an 0-4 record.
