Top contenders in the loaded welterweight division collide on Saturday in the main event of UFC on ESPN 4 as veteran Rafael dos Anjos takes on rising prospect Leon Edwards. The 13-fight card takes place at the AT&T Center in San Antonio, with the main card scheduled for 9 p.m. ET. Edwards is a -120 favorite (risk $120 to win $100), while Edwards is +100 in the latest Edwards vs. Dos Anjos odds. 

Before you make any UFC Fight on ESPN 4 picks, you NEED to see the predictions from SportsLine MMA expert Kyle Marley. He won the first-ever "ToutMaster" UFC betting contest sponsored by MMAOddsBreaker and is in contention to win this year's contest. He also appears regularly on multiple MMA betting and DFS shows. Over the past year, $100 bettors who have followed Marley's picks are up more than $22,000! 

Marley has been massively profitable in 2019. Last week at UFC Fight Night 155, he accurately predicted that Andre Fili (+100) would score a victory over Sheymon Moraes (-120) in front of Fili's hometown fans. The result: Fili delivered with a first-round knockout, and Marley's followers picked up an easy winner. 

Two weeks ago at UFC 239, Marley advised SportsLine members that Jon Jones and Amanda Nunes would be successful in their title defenses. Nunes knocked out Holly Holm and Jones won a decision over Thiago Santos and Marley's followers raked it in once again.

For UFC on ESPN 4, we can tell you Marley is backing Alexander Hernandez (-170) to defeat Francisco Trinaldo (+150) in a lightweight bout on the main card.

"Hernandez will be the faster fighter, throwing strikes at a higher rate. He is more likely to get the knockout and take this fight down," Marley told SportsLine. 

Marley also has extremely confident picks locked in for dos Anjos vs. Edwards and every other bout on the stacked UFC on ESPN 4 card! You ABSOLUTELY need to see his picks before making any of your own.
