RotoBaller Reader Testimonials

RotoBaller readers have been winning their leagues regularly.

“I am very active in fantasy and have been since mid 1980's. Season-long, DFS, and high stakes in multiple sports. I subscribe to a number of tout sites but RotoBaller MLB is truly a one stop reliable source I use every day for fantasy baseball--especially at crunch time. I love to get last minute lineup help that provides a huge edge with their targeted articles I read daily.

- Phil Smith (subscriber since 2017)

“RotoBaller has brought me to the championship for 6 consecutive years. No one else is close due to the deep roster of writers, tools and analysis.

I have been using RotoBaller since I started my endeavors in fantasy baseball -they got all that is needed to conquer your league.

- Anthony B (subscriber since 2013)

“Just wanted to give a shout about the premium sub. I'm in a long time, 12 team, highly competitive season long with my friends and always looking for a leg up. Signed up for the premium for draft prep and waiver/streaming stuff and the info was incredibly solid.

But here's where it really paid off; I used to be pretty big into DFS in the early days but when it started to get super sharp I stopped playing for a few years. With the cheat sheets being such an easy jumping off point, started playing double ups every night and they cashed at an insane rate. From there would throw a lineup in the $12 and other GPP's and those cashed too; one hit for $800 that comes to mind.

The DFS Cheat Sheets pay for the premium subscription in a week it's that simple. Included a screenshot of basically the same thing when I shouted out Nicklaus at the end of last year. Pumped to play again this year.
