Rondon was claimed off waivers by the Pirates on Tuesday.
It appears as if the Pirates and Orioles made a swap of sorts, as Rondon was DFA'd to make room for Vance Worley, who Baltimore claimed off waivers last week. Rondon was dreadful in his ten appearances with the Rockies and Orioles this season, posting a 13.19 ERA and 2.58 WHIP in 14.1 innings. However, his ugly performance in 2015 masks the fact that he was terrific with Triple-A Norfolk -- in 54 innings, the 27-year-old recorded a 2.33 ERA and 1.02 WHIP. Rondon could actually find a spot in the Pirates regular season bullpen if he performs well during spring training, but it's unlikely he will be involved in enough high-leverage situations to make him fantasy relevant.
