Mike Olt

Olt attended Branford High School in Branford, Connecticut, where he played for the school's baseball team. He started at shortstop for the school's varsity baseball team in all four years at Branford. In 2006, Branford won the Connecticut state championship. After graduating high school, Olt was not selected in the 2007 Major League Baseball Draft.

Olt enrolled at the University of Connecticut in Storrs, Connecticut, where he played college baseball for the Connecticut Huskies. He was named a freshman All-American. Olt played for the New England Collegiate Baseball League's Danbury Westerners in 2008. In 2008 and 2009, he played collegiate summer baseball with the Orleans Firebirds of the Cape Cod Baseball League.

The Rangers drafted Olt in the supplemental first round, with the 49th overall selection, of the 2010 MLB Draft. After he signed, Olt played for the Spokane Indians of the Class A-Short Season Northwest League. In 2011, Olt played for the Myrtle Beach Pelicans of the Class A-Advanced, where he batted .267 with 14 home runs. He broke his collarbone in a collision in June, and missed ten weeks of the season. Olt participated in the Arizona Fall League (AFL) after the 2011 season. Olt led the AFL with 13 home runs.

Before the 2012 season, MLB.com ranked him as the 43rd best prospect in baseball. Olt began the season with the Frisco RoughRiders of the Class AA Texas League, and was named to appear in the 2012 All-Star Futures Game. After he batted .287 with 27 home runs and 81 runs batted in (RBIs) for Frisco, the Rangers promoted Olt to the major leagues on August 2. In his debut, Olt recorded a hit in his first at-bat, and went 1-for-3. On August 11, he hit a pinch hit walk-off single to beat the Tigers, 2-1.

The Rangers optioned Olt to the Round Rock Express of the Class AAA Pacific Coast League (PCL) during spring training in 2013. He struggled to begin the season, batting .139 through April 25. He reported problems with depth perception, which specialists indicated could be the result of a concussion. When it was discovered that a lacrimal gland wasn't producing tears, he was given eye drops, which corrected the vision problem. He returned to Round Rock on June 3.

After batting .213 at Round Rock, the Rangers traded Olt to the Chicago Cubs on July 22, 2013, with Justin Grimm, C. J. Edwards, and a player to be named later (Neil Ramirez), in exchange for Matt Garza. Olt reported to the Iowa Cubs of the PCL. He batted .168 in 152 plate appearances with Iowa. He attempted to find a new way to treat his vision problem, as the eye drops he was given raise the chances of developing glaucoma.

At the start of spring training in 2014, Olt reported that his vision problems had been resolved. Olt competed for the starting third base job with the Cubs. He made the Cubs' Opening Day roster, though Cubs' manager Rick Renteria suggested that Olt would split playing time at third base with Luis Valbuena. Olt hit his first major league home run on April 3, and his first grand slam on May 8. Olt was demoted back to Iowa on July 23, 2014 after posting a .139 batting average for the 2014 season. Twelve of his 31 hits were home runs by the time he was demoted, setting an all-time MLB season record for most home runs hit by a batter with an average below .170.

The Chicago White Sox claimed Olt off of waivers on September 5, 2015, and inserted him into their lineup at third base the next day. Olt batted .203 in 24 games for the White Sox. On September 16, Olt hit a home run, becoming the only player in MLB history to hit a home run for both Chicago MLB teams in the same season.

On March 17, 2016, Olt signed a minor league contract with the San Diego Padres. He played primarily for the San Antonio Missions as well as three games for the El Paso Chihuahuas.
