Jeffress has given up two earned runs (2.35 ERA) while posting a 6:5 K:BB ratio in 7.2 innings over six appearances this spring. Jeffress has pitched well this spring, and even better of late, giving up just two walks and no hits over his last four innings. It's unlikely he will open the season with a prominent role in the Brewers' bullpen, but he is essentially a lock to make the team, and should be a factor in the middle relief mix.
