Wander Suero Montero (born September 15, 1991) is a Dominican professional baseball pitcher in the Atlanta Braves organization.

He has previously played in Major League Baseball (MLB) for the Washington Nationals, Los Angeles Dodgers, and Houston Astros.

[1] In 2010, he started four games and appeared in relief 11 times, finishing the season with a record of 2–3, an earned run average (ERA) of 4.72, and 39 strikeouts and 23 walks in 341⁄3 innings.

[4][5] During the championship season, Suero appeared in 13 games, starting three of them, and posted an 8–1 record, with an ERA of 1.65, 46 strikeouts, and 13 walks in 49 innings of work.

[1] Suero was promoted to the Class A Advanced Potomac Nationals in the Carolina League to begin the 2014 season and struck out 21 batters, but walked 10 and pitched to an ERA of 7.57 in 271⁄3 innings of relief.

[9] Returning to Harrisburg as the 2017 season began, Suero had a 1.96 ERA and 10 saves in 23 innings of relief, and he quickly earned a promotion to the Class AAA Syracuse Chiefs of the International League for the first time on June 2, 2017.

He told a Mid-Atlantic Sports Network reporter that his goal was to work hard over the winter to prove to the organization his readiness to pitch in the major leagues.

[16] He pitched for Tigres del Licey in the Dominican Winter League again during the 2017-2018 offseason, but with less success, with five strikeouts, six walks, and an ERA of 7.56 in 81⁄3 innings of work over nine relief appearances.

[1] Suero began spring training in 2018 by pitching four scoreless innings with seven strikeouts and no walks, but he suffered an oblique strain during a Grapefruit League game on March 9.

[17] On April 30, the Nationals called Suero up to the major leagues for the first time to reinforce Washington's bullpen with middle-relief strength.

He threw 15 pitches and gave up two singles to the first two batters he faced, third baseman Colin Moran and shortstop Jordy Mercer, but then got second baseman Max Moroff to pop out to the shortstop and right fielder Adam Frazier to fly out to center field to complete both the inning and his first major league appearance without surrendering any runs.

[25][27] He had pitched 17+1⁄3 innings in 15 major-league appearances on the season, posting a 3.63 ERA, striking out 16, and walking six, when the Nationals optioned him to Syracuse on June 19 to make room on their roster for newly acquired reliever Kelvin Herrera.

[38] He was assigned to the Triple-A Oklahoma City Dodgers to begin the year, making 47 appearances and logging a 3.26 ERA with eight strikeouts and 17 saves in 49+2⁄3 innings pitched.

[42] Suero was added back to the major league roster on September 10[43] where he made one more appearance, allowing one run in 1+1⁄3 innings.

[46] He began the 2024 season with the Triple–A Sugar Land Space Cowboys of the Pacific Coast League (PCL), and made four appearances for the affiliate prior to his promotion.
