MMA action heads to Philadelphia on Saturday night, where the 13-fight UFC on ESPN 2 card promises an action-packed night in the City of Brotherly Love. The UFC on ESPN 2 prelims begin at 5 p.m. ET, with the main card starting two hours later. Headlining will be top-10 ranked lightweights Edson Barboza and Justin Gaethje. Both fighters are dynamic strikers, with Barboza (20-6) taking 12 of his 20 career wins by way of KO/TKO and Gaethje (19-3) stopping 16 of his 19 wins by KO/TKO. Barboza is the -130 favorite, while Gaethje is at +110 in the latest Barboza vs. Gaethje odds, which have remained largely unchanged since the opener. Jack Hermanson will take on David Branch at middleweight in the precursor to the main event, with Hermanson listed as a -130 favorite in the latest Hermanson vs. Branch odds. Before you make your UFC Philadelphia predictions, read the UFC on ESPN 2 picks from SportsLine MMA expert Kyle Marley.

Before you make any UFC on ESPN 2 picks, you need to hear what SportsLine MMA expert Kyle Marley has to say. Marley won the first-ever "ToutMaster" UFC betting contest sponsored by MMAOddsBreaker and appears regularly on multiple MMA betting and DFS shows. He watches every single fight for every single UFC card and does extensive research before each event. 

Over the last 10 months alone, $100 bettors who have followed Marley's picks are up nearly $19,000. It's an astonishing cash rate that shows the depth of Marley's knowledge. 

Just last week, Marley told SportsLine members that Curtis Blaydes would dominate Justin Willis in a battle of rising heavyweight prospects. That's exactly what happened, as Blaydes used his superior athleticism and wrestling to notch a comfortable decision victory. 

Moreover, at UFC 235, Marley advised SportsLine members that underdog Kamaru Usman (+150) would upset champion Tyron Woodley for the UFC welterweight title. He predicted Usman's energy and activity level would be the difference in a unanimous-decision victory. He was on point again, as Usman took control from the opening bell to claim the title belt. In fact, Marley went 9-2 picking fights at UFC 235, and anyone who followed him is way up.

Now, with UFC on ESPN 2 fast approaching, Marley has carefully studied every matchup on the 13-fight card, identified the best value in the UFC odds and released his MMA picks for every single fight. He's sharing them only over at SportsLine. 

Marley knows this bout could be a turning point in the careers of both fighters, who are vying for position in a loaded lightweight division. Barboza, 33, is a veteran of 20 UFC bouts and one of the sport's most respected fighters. But the Brazilian's title prospects dimmed with consecutive losses to Khabib Nurmagomedov, who has since become the champion, and rising contender Kevin Lee. The 30-year-old Gaethje is a former World Series of Fighting champion who has gone 2-2 in four UFC bouts. The crowd-pleasing brawler is coming off his most impressive UFC performance when he stopped Vick with a one-punch knockout at 1:27 of the first round. Marley has locked in his plays, and he's only sharing his Barboza vs. Gaethje picks at SportsLine.

For UFC on ESPN 2, we can tell you Marley is backing Kevin Holland to stop Gerald Meerschaert as a -175 favorite. 

The middleweight bout favors Holland as a striker, as he lands nearly 55 percent of his significant strikes at a rate of 5.38 per minute, while Meerschaert lands just 46 percent at 3.48 per minute. He's also a capable enough wrestler to stunt Meershaert, landing 1.7 takedowns per 15 minutes.

"I expect Holland to have a big edge in the striking department, and he is solid on the ground as well. He could even pull off a submission of his own if he got the fight to the mat," Marley told SportsLine. "Meerschaert has only been to decision three times, so I will take the knockout for Holland as my pick."

Marley also has strong picks for Barboza vs. Gaethje, Hermansson vs. Branch, and every single preliminary match. He's only sharing who to back for every bout on the UFC on ESPN 2 card over at SportsLine.
