De La Rosa was designated for assignment by the Diamondbacks on Friday.

Analysis:

De La Rosa was removed from the 40-man roster following a trade that brought Rubby De La Rosa, Allen Webster and Raymel Flores from the Red Sox and sent Wade Miley to Boston in return. The left-handed De La Rosa posted a 2.95 ERA (3.49 FIP) and 1.39 WHIP with 32 strikeouts in 36.2 innings with the Diamondbacks last season, so another team may be inclined to take a flier on him while on waivers.
