(AP) — Center fielder Kyle Lewis is one of Seattle’s foundational players as the Mariners enter the next stage of their rebuilding plan. He showed enough in last year’s 60-game season for the Mariners to believe they have a burgeoning superstar on their hands and for the rest of the American League to take notice. His mix of raw power to all fields, hitting for average, and proving he can handle the demands of playing center field were major revelations for the Mariners. He ended the season as rookie of the year in the American League.
