On Monday, San Diego traded all three players in two deals that netted two players.
The Padres swapped Brach, a 27-year-old righthander, to the Orioles for righthander Devin Jones. Brach has spent the past three seasons in the Padres' pen and had a 3.19 ERA in 2013, but he walked 19 in 31 innings and has walked 5.1 per nine in his big league career.
Jones, 23, ranked No. 18 in the Orioles system heading into 2013 after a very effective 2012 at low Class A Delmarva and high Class A Frederick. In 2013, however, he posted a 5.84 ERA at Double-A Bowie. Prior to his 2013 struggles, Jones profiled as a mid-rotation starter. As a reliever, he can touch 96 mph.
Mikolas and Decker went to the Pirates for first baseman Alex Dickerson.
Decker, 23, was a supplemental first-rounder in 2008 (No. 42 overall) who reached Triple-A for the first time in 2013. He hit .286/.381/.443 and was ranked No. 23 among Padres prospects prior to the season. Thanks to his patient approach, he probably best profiles as an offense-first reserve outfielder.
Mikolas, 25, profiles as a middle reliever or set-up man with a good curve and fastball that touches 98 mph. He has pitched in the majors, albeit briefly, in each of the past two seasons. He was a seventh-round pick in 2009.
Dickerson, 23, is a San Diego native who played at Indiana and was a third-rounder in 2011 by the Bucs. He hit .288/.337/.494 at Double-A Altoona in 2013.
The Padres previously traded middle infielder Dean Anna, who likely would have been left off their 40-man, to the Yankees for 24-year-old righthander Ben Paullus, who could pitch at Lake Elsinore next season.
To make room on their 40-man roster, the Pirates DFA'd outfielder Garrett Jones and righty Kyle McPherson.
A’s Acquire Abad
Abad, 27, had a 3.35 ERA in 38 innings for the Nats, but did not fare well against lefties (.306/.338/.452). He has a good changeup and a fastball with life, but has had command issues. He won't be eligible for arbitration until after 2014.
