Velasquez will enter camp as the favorite to win the fifth spot in the Phillies' rotation, the team's official site reports.
Velasquez came over to the Phillies as the centerpiece of the Ken Giles trade. He was 1-1 with a 4.37 ERA and a 58:21 K:BB ratio in 55.2 innings with the Astros last season. He will compete with Brett Oberholtzer, Adam Morgan, David Buchanan, Alec Asher and Severino Gonzalez this spring.
