Xander Bogaerts is a strong MLB DFS pick for Monday despite his slow start. He has a favorable matchup against a struggling Colorado Rockies team. Austin Riley and Adam Duvall are also solid options for your DFS lineup. Riley has been on base in 14 consecutive games and is looking for his first home run since April 7. Duvall is a cheap option who has a history of success against left-handed pitchers.
