The Pittsburgh Pirates have acquired right-handed pitcher Allen Webster from the Arizona Diamondbacks for cash considerations. The 25-year-old Webster was designated for assignment by the Diamondbacks last week. He had a 5.81 ERA in five starts and four relief appearances with Arizona in 2015. He has spent parts of three seasons in the majors(the first two with Red Sox), posting a 6.13 ERA over 120.1 innings. From 2012-14, both Baseball America and MLB.com had him as a top 100 prospect each year, ranking as high as 46th in 2014. With this move, and the earlier signing of Jake Goebbert, the 40-man roster is now full.
