HANOVER, N.H. — In the ninth round of the Major League Baseball First-Year Player Draft, the Baltimore Orioles selected Dartmouth junior left-hander pitcher Mitch Horacek with the 279th overall pick. This is the second time he has been chosen in the draft, as the Colorado Rockies took him in the 46th round out of high school in 2010.

Horacek, a 6-5, 210-pound southpaw from Highlands Ranch, Colo., was part of a Dartmouth pitching staff that posted an Ivy League-best 2.75 ERA (15th-best nationally) in helping the Big Green set a school record with 32 victories. In eight games this spring, he posted a 6-2 record with a 2.20 ERA over 45.0 innings. The opposition hit just .241 against Horacek as he struck out 42 batters and walked just 10, giving him the second-best strikeout-to-walk ratio (4.2) in the Ivy League. In only one of his seven starts did he allow more than two runs, and in each of his two losses, the Big Green were shut out.

In his three seasons at Dartmouth, Horacek has a record of 13-7 with a 4.82 ERA, hurling 140.0 innings with 106 strikeouts while walking only 28.

Horacek is the 29th Big Green player and 34th Dartmouth selection in an MLB Draft, with at least one being chosen in each of the past six years. Only two of the last 17 Big Green players selected in the draft (spanning the past 20 years) were taken earlier than the ninth round — right-hander Kyle Hendricks in 2011 and Ed Lucas in 2004, both of whom were picked in the eighth round. Hendricks, currently pitching for the AA Tennessee Smokies, was named the Chicago Cubs’ organization pitcher of the month in May, while Lucas made his major league debut with the Miami Marlins on May 30.
