Ross Ohlendorf is a former professional baseball player who played as a pitcher in Major League Baseball (MLB) for several teams. He was born on August 8, 1982, in Austin, Texas, and attended Princeton University, where he played college baseball for the Princeton Tigers.

Ohlendorf was drafted by the Arizona Diamondbacks in the fourth round of the 2004 MLB draft. He made his MLB debut with the Diamondbacks in 2007, but he was traded to the New York Yankees later that year. Ohlendorf played for the Yankees for two seasons, from 2007 to 2008, before being traded to the Pittsburgh Pirates in 2009.

Ohlendorf spent three seasons with the Pirates, from 2009 to 2011. He had his best season in 2009, when he posted a 11-10 record with a 3.92 ERA in 29 starts. Ohlendorf was known for his strong work ethic and his ability to pitch deep into games.

After leaving the Pirates, Ohlendorf played for several other teams, including the San Diego Padres, Washington Nationals, Texas Rangers, and Cincinnati Reds. He was primarily used as a relief pitcher during this time, although he did make some starts as well.

Ohlendorf's career was hampered by injuries, particularly to his shoulder. He underwent surgery in 2013 to repair a torn labrum in his shoulder, and he missed most of the 2014 season as a result. He also suffered a strained groin in 2015 that kept him out of action for several weeks.

Despite his injuries, Ohlendorf continued to pitch in the majors until 2016. He finished his career with a 30-43 record and a 4.87 ERA in 146 games (97 starts). Ohlendorf was known for his intelligence and his ability to analyze his own performance, and he was respected by his teammates and coaches for his work ethic and his dedication to the game.

After retiring from baseball, Ohlendorf returned to Princeton University to complete his degree in operations research and financial engineering. He also worked as a coach for the Princeton Tigers baseball team, helping to develop young players and sharing his knowledge and experience with the next generation of baseball stars.
