Michael Christopher Moustakas (/muːˈstɑːkəs/; born September 11, 1988) is an American professional baseball third baseman who is a free agent.

During that time he helped Chatsworth to a 124–11 record, including four West Valley League championships, and two California Interscholastic Federation city titles.

He topped off his prep career by being named Baseball America's High School Player of the Year in 2007, an honor previously bestowed on MLB stars like Joe Mauer, Homer Bailey and Josh Hamilton.

[8] Chatsworth teammate Matt Dominguez was chosen by the Florida Marlins with the 12th overall pick of the amateur draft.

While his power remained, his ability to hit for a high average went down significantly as he adjusted to the new level of competition.

[12] On August 30, 2010, Moustakas was named the 2010 Texas League Player of the Year and on the same night, he set an Omaha Royals record with three home runs and 11 RBIs in one game.

His first major league hit came in his third plate appearance against Ervin Santana, where he would eventually score in the 4–2 win.

[2] Moustakas finished the year batting .242 with a .296 OBP with 20 home runs and 73 RBIs, also hitting 34 doubles.

On May 22, 2014, he was demoted to Triple-A Omaha after batting just .152 through 139 plate appearances, though he led the team in homers with 4.

On September 12, Moustakas set a new Royals franchise record against the Baltimore Orioles with 9 RBI, eclipsing the previous mark of seven.

On May 22, Moustakas suffered a right knee injury while colliding with teammate Alex Gordon in an attempt to fetch a pop up in foul territory.

[21] Moustakas won the All-Star Final Vote for the second time of his career on July 6, 2017, and participated in the Home Run Derby.

Moustakas became a free agent after the 2017 season once he turned down the Royals' $17.4 million qualifying offer.

Expecting to receive a longer-term deal on the market for more guaranteed money, he instead found no interest from other teams.

[24] On July 28, 2018, the Royals traded Moustakas to the Milwaukee Brewers in exchange for Brett Phillips and Jorge López.

On October 4, 2018, Moustakas hit a walk-off single in the 10th inning of NLDS Game 1 vs the Colorado Rockies, giving the Brewers a 3–2 win and a 1–0 series lead.

[26] On February 19, 2019, Moustakas re-signed with the Brewers, inking a one-year, $10 million deal with a mutual option for 2020.

[35] Moustakas played in 78 games for Cincinnati in 2022, posting a .214/.295/.345 batting line with 7 home runs and 25 RBI.

[38][39] On March 25, the Rockies announced Moustakas had made the Opening Day roster after hitting .367/.387/.700 with two home runs in 31 plate appearances during spring training.

[49] Asked by USA Today what career he would enjoy other than baseball, Moustakas expressed an interest in being a firefighter.
