Kolten Kaha Wong (born October 10, 1990) is an American professional baseball second baseman who is a free agent.

He has previously played in Major League Baseball (MLB) for the St. Louis Cardinals, Milwaukee Brewers, Seattle Mariners, and Los Angeles Dodgers.

Wong was the Cardinals' starting second baseman for the majority of his tenure with the team, and won two Gold Gloves and three Fielding Bible Awards with the club.

During the 2020 offseason, the Cardinals declined Wong's player option for the 2021 season, making him a free agent for the first time in his career.

[2] Instead of pursuing a steady career, he took whatever jobs would afford him the most time to teach Kolten the game and about working out, which he emphasized on a daily basis.

He participated in the Cal Ripken World Series in Aberdeen, Maryland where he led his team, Pacific Southwest, to the championship.

The Rainbow Warriors won a Western Athletic Conference (WAC) tournament in his sophomore year and a regular season championship.

[8][9] His batting average (.341) ranked him third in the CCBL that summer, his slugging (.452) was fourth, OBP (.426) second, and stolen bases (22) second, while making just four errors in 145 chances for a .972 fielding percentage.

[12] He finished his college career with a .358 batting average (245 hits in 684 at-bats), 47 doubles, 25 home runs, 145 RBIs, a .563 SLG and .449 OBP.

[15] After earning a promotion to the Springfield Cardinals of the Double–A Texas League in 2012, Wong batted .287 with 52 RBIs and 21 stolen bases.

[16] Wong finished the year playing in the Arizona Fall League (AFL), where he batted .324 with 12 RBIs and five stolen bases.

[18] His totals at Memphis included a .303 batting average with 10 home runs, 45 RBIs, and 20 stolen bases in 107 games, before the Cardinals called him up to the Major Leagues on August 16.

[25] He returned to the MLB club in May after hitting .344 with two homers, five steals, and an .867 on-base plus slugging (OPS) in 15 games, and also developed a modified swing.

[27] Wong's plus-7 defensive runs saved led NL second basemen despite spending time in the minor leagues.

[27] On June 3, he hit his first career MLB home run, a grand slam against the Royals ace James Shields.

[29] But when he reaggravated a shoulder injury sustained earlier in the month, the Cardinals placed Wong on the 15-day disabled list (DL) on June 21.

[30] After returning from the DL, Wong hit a double to tie the score 2–2 in the second inning of a July 8 contest against the Pittsburgh Pirates.

With the score tied 4–4 in the bottom of the ninth of that game, he hit his first walk-off home run off Ernesto Frieri.

In Game 3 of the NLDS versus the Los Angeles Dodgers, his seventh-inning, two-run homer broke a tie and provided the final margin in the Cardinals' 3–1 victory.

[37] In Game 2 of the NLCS against the San Francisco Giants on October 12, Wong hit his second career MLB walk-off home run, a solo shot that secured a 1–1 tie in the series for the Cardinals.

In MLB postseason history, Wong became the third second baseman to accomplish the walk-off feat, after Bill Mazeroski (1960 World Series) and Jeff Kent (2004 NLCS).

[47] In his debut with Memphis, he hit two home runs, including a grand slam, in an 8−5 win over Colorado Springs.

[49] His ninth-inning, RBI double in the July 27 game against the New York Mets drove in the game-winning run for a 5−4 final score, where Jeurys Familia’s consecutive-saves streak had ended one batter earlier to Yadier Molina at 52, the third-longest in major league history.

[52] On May 5, 2018, Wong hit a walk-off home run against Chicago Cubs reliever Luke Farrell in the bottom of the ninth inning.

[53] On June 2, Wong hit a walk-off home run versus Richard Rodríguez of the Pittsburgh Pirates for a 3–2 win.

[57] Wong finished his 2019 regular season slashing .285/.361/.423 with 11 home runs, 59 RBIs, and 24 stolen bases over 148 games.

[66] Wong opened the season in a platoon at second base, but struggled and began to lose playing time to José Caballero by May.

[83] They reside in Honolulu, Hawaii during the offseason, and also owned a home in Creve Coeur, Missouri, but sold it after Wong signed with Milwaukee.

[87] Wong began fundraising to help families impacted by the 2018 lower Puna eruption in May 2018[88] by creating a GoFundMe page that has raised over $58,000.
