Orioles land Brach from San Diego
BALTIMORE (AP) The Orioles have acquired right-handed reliever Brad Brach from the San Diego Padres for a minor league pitcher.
The 27-year-old Brach had a 3.19 ERA in 33 games last season with the Padres, striking out 31 in 31 innings. In three seasons with San Diego, Brach went 3-6 with a 3.70 ERA over 109 appearances.

Jones was selected by Baltimore in the ninth round of the 2011 amateur draft out of Mississippi State.
A's get Abad from Nationals
Abad could help bolster a talented bullpen that has likely has lost closer Grant Balfour in free agency, with the ninth-inning spot expected to be filled from within by Sean Doolittle or Ryan Cook.

The 27-year-old Abad, who was designated for assignment last Wednesday, went 0-3 with a 3.35 ERA in 39 appearances for the Nationals last season. He spent 2010-12 with the Houston Astros and has a career record of 1-14 with a 4.56 ERA in 127 outings.
Wooten batted .257 with 20 home runs and 69 RBIs for Class A Beloit this year. He was a 37th-round selection by Oakland in the 2012 amateur draft out of East Carolina. The Nationals said he won't be added to their 40-man roster but will join the club's minor league system.
