Péter Kozma

On July 4, 2020, it was announced that Kozma had tested positive for COVID-19. He became a free agent on November 2, 2020.

On November 19, 2019, Kozma signed a minor league deal with the Atlanta Braves.

On January 9, 2018, the Detroit Tigers signed Kozma to a minor league contract with an invitation to spring training. He started the season with the AAA Toledo Mud Hens. On May 8, 2018, the Tigers purchased Kozma's minor league contract and added him to the major league roster. He hit a home run in his first at-bat for the Tigers the next day. He was designated for assignment on June 1, 2018. After clearing waivers, Kozma was sent outright to Toledo from the Tigers on June 5, 2018. On September 14, 2018, the Tigers again purchased Kozma's contract from Toledo to add infield depth. In 27 games, he hit .217 with one home run and eight RBIs.

On April 30, 2017, the Texas Rangers claimed Kozma off of waivers. He played as a backup utility infielder. On July 20, 2017, he was designated for assignment.

The New York Yankees signed Kozma to a minor-league contract. He spent the 2016 season with the Scranton/Wilkes-Barre RailRiders helping the team win the International League and AAA Championships. He signed a contract with the Yankees for the 2017 season. Due to an injury to Didi Gregorius, the Yankees added Kozma to their Opening Day roster. He was designated for assignment on April 28, to make room for Gregorius' return.

The following spring training, Kozma resumed working out at all infield positions, and added time as a catcher. On June 25, 2015, against the Miami Marlins, he scored on a double from Kolten Wong. He had three hits and reached base in four plate appearances, snapping an 0–21 streak that dated back to May 19. Kozma totaled 99 at bats for the season, batting .152 with a .236 on-base percentage and no extra base hits. The Cardinals removed him from the 40-man roster after the season and re-assigned him to Memphis. He opted to become a free agent.

The following off-season, the Cardinals signed longtime American League player Jhonny Peralta as a free agent to upgrade their offense at shortstop, thus supplanting Kozma from his short-lived status as the starter. The Cardinals signed Mark Ellis, another free agent, and kept rookie second baseman Kolten Wong on the MLB roster for much of the season. Those three moves relegated Kozma to spending most of 2014 playing for Memphis, where he hit .248 with eight home runs and 59 RBI. The Cardinals recalled him when MLB rosters expand in September, and in 14 games hit .304 with three doubles. The club won the NL Central division, assuring a playoff berth for the fourth time in his four seasons with the club. He was a last-minute addition to the postseason roster for the NLDS against the Dodgers.

Kozma became the Cardinals' primary shortstop in 2013 and finished with a .217 batting average, 20 doubles, a home run and three stolen bases in 143 games. They secured the best record in the National League, thus making the playoffs. He provided a key defensive play in the sixth inning of Game 3 of the NLCS against the Los Angeles Dodgers. Dodgers batter Juan Uribe hit a rapid ground ball in the hole, which Kozma backhanded and relayed to second baseman Matt Carpenter, tipping off an inning ending double play. The Cardinals won the game, 4–2.

A sure-handed defender with excellent range and throwing arm, Kozma primarily plays shortstop. In the 2012 National League Division Series against the Washington Nationals, his 9th inning hit of the deciding Game 5 drove in the go-ahead run and allowed the Cardinals to advance to the National League Championship Series.

On May 18, 2011, Kozma was called up from the AAA Memphis Redbirds, with whom he hit .214 in 112 games, to the major league club to replace injured middle infielder Nick Punto. He made his major league debut that night, and hit a double with an RBI in his first at-bat when pinch-hitting in the 5th at Busch Stadium. Kozma was part of the Cardinals' postseason roster when the team won the 2011 World Series over the Texas Rangers.

In 2009, Kozma split the season between Palm Beach (18 games) and the Springfield Cardinals (113 games), hitting .231 with six home runs and 45 RBI in 131 games. He played for Springfield in 2010, hitting .243 with 13 home runs and 72 RBI in 132 games. He also stole 13 bases in 15 tries.

Kozma played for the Quad Cities River Bandits (99 games) and Palm Beach Cardinals (24 games) in 2008, hitting a combined .258 with five home runs and 50 RBI in 123 games. He also stole 12 bases in 18 attempts.

The St. Louis Cardinals selected Kozma in the first round, with the 18th overall selection, of the 2007 Major League Baseball draft. In his first professional season, Kozma played for three minor league teams—the Johnson City Cardinals (30 games), GCL Cardinals (four games) and Batavia Muckdogs (eight games). Overall, he hit .233 with two home runs and 11 runs batted in (RBIs) in 42 games that season.
