Derek Lane Holland (born October 9, 1986) is an American professional baseball pitcher who is currently a free agent. He previously played for the Texas Rangers and Chicago White Sox. He is nicknamed the Dutch Oven. 
Holland has the ability to throw a variety of pitches to right-handed hitters and left-handed hitters at different speeds. His primary pitch is a four-seam fastball averaging 94-95 mph. To lefties, he throws the four-seamer, a two-seamer, and a slider (82-85). To righties, he throws a balance of the aforementioned pitches as well as a changeup in the mid 80s and a curveball in the mid-high 70s. Holland relies heavily on his slider with two strikes to both right-handed and left-handed hitters. 
Holland was drafted in the 25th round in 2006 out of Wallace State Community College in Hanceville, Alabama, a member of the National Junior College Athletic Association.

Holland pitched a scoreless relief inning in a game four 4-0 loss, but he and the Rangers lost the series 4-1.
Holland started the 2011 season as a starter for the Rangers, and despite a 4.96 ERA, won four of his five starts in April and May.
