One down, likely many more to go for Marcelo Mayer.
The Boston Red Sox' No. 4 overall pick in the 2021 MLB Draft collected his first professional hit Tuesday, a grounder up the middle for the Florida Complex League Red Sox.
Mayer made his pro debut Aug. 5, walking in his first three plate appearances and grounding out in his fourth. After his base his, the 18-year-old shortstop is now 1-for-5 with three walks, a strikeout and a run scored in seven total plate appearances.
