 On August 31 , 2003 the Marlins traded Bautista and fellow minor leaguer Don Levinski to the Baltimore Orioles for veteran Jeff Conine . Before the 2004 season , Baseball America ranked him the Orioles ' fifth @-@ best prospect . The Orioles assigned Bautista to the Double @-@ A Bowie Baysox of the Eastern League , where he went 3 – 5 with a 4 @.@ 74 ERA , 72 strikeouts , 33 walks , and 62 2 ⁄ 3 innings pitched in 14 games ( 13 starts ) during the 2004 season . Bautista made his major league debut that year : the Orioles called him up as part of a roster reshuffle , and he made his first appearance , in relief , on May 25 , 2004 , against the New York Yankees . He recorded three outs in the first inning he pitched , but he got into difficulties and surrendered four runs on three hits before getting removed during his second inning . After a second relief appearance on May 27 ( in which he allowed four runs in 1 ⁄ 3 of an inning ) amid a three @-@ game sweep of the Orioles by the Yankees , Bautista was sent back to Bowie . A month later the Orioles traded him to the Kansas City Royals for veteran relief pitcher Jason Grimsley .
