Bell, who will be a free agent after this season, was hitting .278 with six home runs and 34 RBI in 91 games. The Phillies got Class A right-hander Wilfrido Laureano. He was 3-2 with a 3.96 ERA in 29 relief appearances for West Virginia of the South Atlantic League.
The disappointing Phillies (46-54) are expected to make more significant moves before Monday's trade deadline. Milwaukee, one of several losing teams in the NL wild-card race, already made a big deal, sending All-Star slugger Carlos Lee to Texas earlier in the day.
