There is far more than meets the eye in this matchup making the Marlins a highly attractive home underdog.

The Phillies are feeling fat and happy being the surprise leaders of the NL East and coming off a 5-4 road win against the Orioles on Thursday. The Phillies had to play the Mets in New York on Wednesday. So this marks their third different road venue in three days. 

Miami was idle on Thursday. The rested Marlins are proving they aren't the bottom feeder many envisioned going into the season. Miami is a respectable 34-40 in its last 74 games. The Marlins are 6-1 the past seven times they've faced a righty starter at home. They draw righthanded Jake Arrieta here.

Arrieta isn't close to being the elite pitcher he was during his Cy Young Award-winning 2015 season. He's given up three or more earned runs in five of his last seven starts. He's 3-4 on the road with a 4.64 ERA. Philadelphia is 2-5 during Arrieta's past seven away starts. Arrieta has struggled during his two starts against the Marlins this season with a 9.39 ERA in 7 2/3 innings. 

The Marlins get back their best player, catcher J.T. Realmuto. He had missed the past three games because of paternity leave. 

While Arrieta has struggled on the road, Miami pitcher southpaw Wei-Yin Chen has thrived at home with a 1.89 ERA in six starts at Marlins Park. The Marlins have won 12 of Chen's last 16 home starts. 

Chen is the first lefty starter the Phillies have faced since July 1, a span of 10 games. They have seen only two southpaw starters since June 15. The Phillies are 1-5 the last six times they've gone against a lefty starter.
