Building MLB DFS lineups this Friday? See what SportsLine's DFS Guru Jacob Gibbs has to say first. Gibbs is a data-driven Daily Fantasy Sports specialist who's never had a losing season.

Previously an analyst at numberFire, Jacob got his start in DFS six years ago, turning a $25 deposit into nearly $3,000 his first season. Gibbs crushed MLB season last year, cashing around 58 percent of the time in cash games and nearly 45 percent of the time in tournaments. He also develops proprietary rankings and projections, which help him find the best DFS values and create profitable lineups. Be sure to check his lineups and player pool out daily before setting your own lineups.

Tonight, Gibbs is focusing on a value stack with big-time upside that helps fit in stud pitchers like Jack Flaherty and Eduardo Rodriguez. View which salary-saving stacks he's targeting here!
