The tallest player in the major-leagues is now a member of the Minnesota Twins, according to an MLB press release. The 6′11” Rauch is a former third-round pick by the Chicago White Sox, but was traded to the Expos back in 2004. He became a Diamondback in mid-2008.

Rauch is 30 years old and has an ERA of 4.14 this year, which helps make him 9 percent better than league average, according to his ERA+ of 109. (Rauch has a career ERA of 3.87 and and an ERA+ of 112.) Rauch has a decent SO/BB ratio of 2.06, and walks just under three batters per nine innings while striking out just under six per.

His pitch arsenal includes a low-90s fastball, a mid-80s slider, a high-80s cutter, a mid-70s curveball, and a mid-80s changeup. Clearly, Rauch knows how to throw a ton of pitches, and he used to be a starter before a series of injuries forced him to the bullpen.

Rauch is under contract for the 2010 season at around $3 million, so this trade will have a much higher impact than the Mahay acqusition. The Twins reportedly gave up a Player To Be Named Later, which hopefully isn’t a top prospect.
