OAKLAND, Calif. – The Oakland A’s acquired catcher John Jaso from the Seattle Mariners in a three-team trade, the club announced today. The A’s sent minor league right-handed pitchers A.J. Cole and Blake Treinen and a player to be named later to Washington and the Nationals dealt outfielder Michael Morse to Seattle. To clear a spot on the 40-man roster, the A’s designated catcher George Kottaras for assignment.
Jaso batted .276 with 10 home runs and 50 RBI in 108 games with Seattle last year. He also walked 56 times for a .394 on-base percentage and batted .378 with runners in scoring position. The 29-year-old left-handed hitter had career highs in batting, on-base percentage, slugging percentage (.456), home runs, RBI and stolen bases (5). Jaso made his Major League debut with Tampa Bay in 2008 and spent three seasons with the Rays (2008, 10-11) before he was traded to Seattle following the 2011 season. He is a .255 career hitter in 311 games.
Cole combined for a 6-10 record and a 3.70 ERA in 27 starts with the A’s two Single-A affiliates last year. After starting the year by going 0-7 with a 7.82 ERA in eight starts with Stockton, he was transferred to Burlington where he was 6-3 with a 2.07 ERA in 19 starts. Cole was acquired by the A’s from Washington Dec. 23, 2011 in the Gio Gonzalez trade.
