Hawpe was placed on the DL retroactive to Sunday. He's had soreness in that finger this season, though he aggravated it taking a swing Saturday in Minnesota.
"He's got to get physically right, and right now he's not," San Diego manager Bud Black said of Hawpe, who is hitting .231 with four home runs and 19 RBIs.
Hawpe, who missed five games last week with a sore left elbow, has enough swelling and soreness in the finger that he can't swing a bat.
"We have been treating it for the last four days," said Hawpe, who is hoping that his time on the disabled list will allow time for his finger and his elbow to heal.
The Padres recalled catcher Kyle Phillips from Triple-A Tucson before Tuesday's game to take Hawpe's roster spot.
Phillips hit .239 with two home runs and eight RBIs in 21 games for the Padres earlier in May and part of June while catcher Nick Hundley was on the disabled list with a strained oblique.
The addition of Phillips will give the Padres another left-handed bat off the bench.
