A year after he was named the Washington Nationals’ Minor League Pitcher of the Year, 27-year-old reliever Wander Suero made his MLB debut last summer, posting a 3.59 ERA, 3.48 FIP, 15 walks (2.83 BB/9), 47 Ks (8.87 K/9), and a .238/.312/.408 line against over 40 games and 47 2⁄3 innings pitched.
Suero talked this winter about what he’d learned from his first exposure at the major league level. His big takeaway was that he needed to work on his curve, after opposing hitters put up a .280 AVG on his breaking ball, hitting three of the four homers he allowed on the pitch.
