Eflin is likely the top candidate to replace Vince Velasquez in the Phillies' rotation, Matt Breen of the Philadelphia Inquirer reports.
Velasquez appears to be headed toward a stint on the disabled list after leaving his start Wednesday with biceps soreness. Eflin was scratched from his start Wednesday evening at Triple-A Lehigh Valley where he is 5-1 with a 3.14 ERA and a 51:8 K:BB in 63 innings. He's worth a look in deeper leagues given his success in the minors this season.
