Breakout seasons at the age of 29 usually result in an outlier season. Marcus Semien will try to shatter the mold in 2020 following up his success from last year. Semien set career highs in most fantasy categories along with some team records as well. He scored 123 runs tying a franchise record for Oakland set by Reggie Jackson in 1969, this also ranked third in the American League in 2019. Among his peers in the American League, Semien finished second in total bases (343), third in doubles (43), extra-base hits (83), fifth in hits (187), sixth in walks (87) and ninth in plate appearances per strikeout (7.32). Semien also led the American League shortstops in fielding percentage (.981) which potentially fueled his surge on offense. Think of him like a catcher who worked at his craft then finally focused on his hitting.

Semien sowed the seeds of this within his plate discipline. Check his growth in the last three seasons in each of these metrics:
