It was previously reported in November that the Phillies could pursue major free agents before making decisions on signing Bryce Harper or Manny Machado, the two biggest stars available in free agency.
After missing out on Patrick Corbin, Keuchel could provide the Phillies with a needed left-handed option for their rotation.
2019 projected rotation
Keuchel, who won a Cy Young in 2015 with the Houston Astros, pitched 204 2/3 innings last season but also allowed a major-league leading 211 hits. He still managed a 3.74 ERA and 3.69 FIP in 34 starts.
Britton could provide the Phillies' bullpen with a third southpaw and a pitcher with 142 career saves under his belt.
