Grissom went 3-for-4 with a run scored in Friday's 2-1 loss to Tampa Bay.
Grissom, who started for the fourth time in the last five games, is 7-for-18 (.389) with a double, two RBI and two steals since being called up last week. It was a rough year for the 23-year-old, whose spring training groin/hamstring injury lingered for months. A positive finish to the season, including a productive stint at Triple-A Worcester, should put him in line to be Boston's starter at second base in 2025.
