Wells, 44, was designated for assignment by his hometown San Diego Padres on Aug. 9 and placed on release waivers four days later. He cleared waivers last Thursday and became a free agent.
REDS: Placed pitcher Bobby Livingston on the 15-day disabled list with a torn labrum in his left shoulder and recalled right-hander Todd Coffey from Triple-A Louisville.
Livingston was 3-3 with a 5.27 ERA in 10 starts. He will be re-evaluated in about 10 days. Catcher David Ross also was sent to Louisville on a rehab assignment.
PHILLIES: When he connects, Ryan Howard can hit the ball a long way. Making contact is the slugger's biggest problem.
The reigning NL MVP is on pace to set the major league record for strikeouts in a season. Howard had 151 strikeouts in 108 games entering Friday night. At this rate, Howard would finish with 201 Ks.
BREWERS: Prince Fielder had his three-game suspension reduced to two games, and planned to start serving it Friday night in San Francisco.
Fielder was suspended and fined an undisclosed amount for "inappropriate and aggressive conduct" during a confrontation with plate umpire Wally Bell on Aug. 12.
TIGERS: Recalled the injury rehabilitation assignment of left-handed pitcher Andrew Miller, a day after they optioned the contract of right-hander Zach Miner to Triple-A Toledo.
Miller started two games for Toledo and had a 9.00 ERA over six innings. The rookie was 5-4 with a 4.42 ERA with the Tigers - entering his start in the series opener against the New York Yankees - before going on the disabled list Aug. 5 with a left hamstring strain. He was the sixth pick overall in last year's June draft.
Miner was 2-3 with a 3.86 ERA in 24 games, including one start.
INDIANS: A minor leaguer was suspended 50 games for violating baseball's minor league drug rules.
Juan Valdes, an outfielder for Class-A Mahoning Valley of the New York-Penn League, tested positive for a performance-enhancing substance.
Valdes is the 25th violation this year, the 22nd under the minor league program.
DEVIL RAYS: Shut down center fielder Rocco Baldelli's rehabilitation because of soreness.
Baldelli was shut down after sitting out Class-A Vero Beach's game Wednesday. Baldelli has felt soreness since his rehab stint began August 18.
Baldelli, who's been on the DL since May 17 because of a hamstring injury, started two games at designated hitter, going 0-for-5 at the plate. Manager Joe Maddon said Baldelli will be re-evaluated Monday.
