The Phillies future is spread out across the team's four main farm teams, and the success or failure of the franchise's long term depends on its recently refueled farm system.

Several prospects are expected to land in South Philly this season, while others will (hopefully) navigate toward the top of the farm as 2016 progresses.

Here's a look at who's hot and who's not among the young talents in the Phillies' system:

Who's hot

Zach Eflin: The 22-year-old hurler has had two outstanding starts for the Lehigh Valley Iron Pigs, having allowed a single run through 14 innings pitched. He's struck out eight and walked just two. 

Mark Appel: He's only started once for Lehigh Valley, but the former Ranger has looked solid in five and two third shutdown, scoreless innings.

Jorge Alfaro: The Phillies' possible catcher of the future has been red-hot since the season began, and recently won Eastern League Player of the Week honors. He has a .500 batting average in eight games (18-for-36).

J.P. Crawford: As expected, the No. 4 prospect in baseball has settled in nicely for the Reading Fightin' Phils, and has batted .310 during the season's first 10 games. 

Ben Lively: The player acquired in 2014's Marlon Byrd trade to the Reds, Lively is in Reading and has had two solid outings thus far, with an ERA of 3.27 to show for it. He's struck out 16 and walked just two. 

Who's not

Jake Thompson: In Triple-A, Thompson has struggled in two starts, allowing seven runs in just eight innings pitched. 

Nick Williams: The Phillies hope Williams will become a slugging, home run threat in the middle of the order someday in the not-too-distant future. But he hasn't been that at all through eight games in Triple-A, smacking just five hits in 26 at bats for a .192 batting average and no home runs.

Roman Quinn: The Phils ' speedy outfield prospect has just eight hits in 39 at bats but does have a team-leading four stolen bases for Double-A Reading.

Alec Asher: The 24-year old has played for both Triple-A Lehigh Valley and for the Phillies, but is currently in Double-A working on a few things. He's been hit or miss, allowing two earned runs in two quality starts but also five in an ugly April 12 loss. He has surrendered 20 hits in three starts.

Cornelius Randolph: The Phillies No. 1 overall pick from a year ago is struggling in A-ball, with a .108 batting average through nine  games and 37 at bats.
