A's bring over Moscoso in trade with Texas

Righty Philip Humber, whom the A's claimed off waivers from the Royals on Dec. 17, was designated for assignment to make room for Moscoso on the 40-man roster.
The 27-year-old Moscoso most recently pitched for Caracas in the Venezuelan Winter League, compiling a 3-0 record and 2.66 ERA in 10 games, eight of which were starts. That stint followed a 2010 campaign in which Moscoso went 7-7 with a 5.18 ERA in 23 games -- 22 starts -- for Triple-A Oklahoma City. He struck out 107 and walked 49 in 123 1/3 innings.
Moscoso boasts 11 career Major League appearances -- only one of which came last year, following a 2009 season that resulted in a 3.21 ERA in 10 games with the Rangers. That lone '10 appearance lasted just two-thirds of an inning against Baltimore on May 20, when he allowed two runs on two hits and two walks for a 27.00 ERA.
Kelly was recently acquired by the A's from Pittsburgh in a Minor League deal that sent speedy infield prospect Corey Wimberly to the Pirates less than a month ago. He was 2-3 with four saves and a 4.20 ERA in 38 games -- all but one in relief -- with Class A West Virginia in 2010.
