PHILADELPHIA -- The Phillies are in the early stages of a rebuilding effort, which means there will be plenty of new faces in camp. In the second part of a seven-part series previewing their Spring Training camp in Clearwater, Fla., MLB.com looks at a few of the most notable newcomers:
RHP Jeremy Hellickson: The Phils acquired Hellickson from the D-backs in a Nov. 14 trade for Minor League pitcher Sam McWilliams. Hellickson, 28, went 9-12 with a 4.62 ERA in 27 starts last season with Arizona.
"We made it a priority to add a stabilizing influence to our young rotation, and we think we found that guy in Jeremy," general manager Matt Klentak said. "He's a veteran guy, but still just 28 years old. He'll pitch at 29 this season, so we're excited that he's still in his prime. And more than anything, he's a competitor. He wants the ball. We've talked about building an environment, and we think he'll be a very positive influence on our staff."
Hellickson can become a free agent after the season, so he has plenty of motivation to pitch well.
• Spring Training preview Part I: Phillies hoping Asche, others bounce back
RHP David Hernandez: The 30-year-old righty signed with the Phillies as a free agent on Dec. 9, and he has an opportunity to be the team's closer with incumbent Ken Giles having been traded to the Astros. Hernandez certainly has the most experience of any reliever on the 40-man roster, although there are some non-roster invitees who could challenge him.

RHP Michael Mariot: Claimed off waivers from Kansas City on Nov. 30, Mariot posted a 6.11 ERA in 19 appearances over the past two seasons with the Royals, although he had a 2.32 ERA in 42 appearances with Triple-A Omaha. He will be in the running for a bullpen job.
RHP Charlie Morton: The Phils acquired Morton in a Dec. 12 trade with the Pirates because the club wanted another veteran in the rotation. He went 9-9 with a 4.81 ERA in 23 starts last season. Morton is set to become a free agent after the 2016 season, although he has a $9.5 million mutual option for 2017.
LHP Brett Oberholtzer: The Phillies acquired Oberholtzer in the Giles trade, and he stands an excellent chance to make the Opening Day roster. If he does not make the rotation, he seems likely to make the bullpen, especially considering he is out of options. Though that is only one factor in Oberholtzer's strong chance to make the team: It simply is hard to believe the Phils would acquire him in December and potentially lose him before the beginning of the season.

LHP Daniel Stumpf: The Phillies selected Stumpf in the Rule 5 Draft, which means he will get a good look at a bullpen job. He went 5-4 with a 3.57 ERA in 42 games last season with Double-A Northwest Arkansas. Stumpf struck out 76 in 70 2/3 innings, holding opponents to a .212 average, including just a .167 average for left-handers.
RHP Vincent Velasquez: The key piece in the Giles trade has an excellent chance to make the rotation behind Hellickson, Morton, Aaron Nola and Jerad Eickhoff. Yes, Velasquez pitched in the bullpen last season with Houston, but that was to reduce his workload. The Phils view him as a starter, and he will be stretched out this spring.
OF Peter Bourjos: Part 1 of this series mentioned that Bourjos is looking to bounce back from some injury-riddled seasons that affected him at the plate. He will get every opportunity to prove himself this year. The only question seems to be where will Bourjos play in the outfield.
OF Tyler Goeddel: The Phillies selected Goeddel with the No. 1 pick in the Rule 5 Draft, so he stands a good chance at making the outfield along with Bourjos, Odubel Herrera, Aaron Altherr and Cody Asche.
RHP Andrew Bailey, RHP Ernesto Frieri, RHP Yoervis Medina, RHP Edward Mujica, LHP James Russell: These five non-roster invitees have big league experience. And with Giles gone, there is an open competition for the closer and setup roles. It would not be a surprise to see one or more of these five make the bullpen.
OF David Lough: Philadelphia considers Lough, who is a non-roster invitee, a better backup oiutfield option than free agent Jeff Francoeur, if something happens to Bourjos, Herrera, Altherr, Asche or Goeddel. Lough hits left-handed, and he posted a .555 OPS in 144 plate appearances last season with Baltimore. He has a .672 OPS in his career.
