Cubs announce roster moves for September 6

The Chicago Cubs today activated right-handed pitcher Hector Rondon from the 15-day disabled list, recalled right-handed pitcher Spencer Patton, outfielder Albert Almora Jr. and infielder Munenori Kawasaki from Triple-A Iowa, and selected the contract of catcher Tim Federowicz (uniform number 19) from Iowa. 
 
To make room for Federowicz on the 40-man roster, right-handed pitcher R.J. Alvarez has been designated for assignment. Chicago's active roster now stands at 34 players.
 
All five players will be available for the Cubs tonight when they continue their three-game series against the Milwaukee Brewers at Miller Park. 
 
Rondon, 28, was placed on the 15-day disabled list with a right triceps strain on August 19 (retroactive to August 17). He is 2-3 with five holds, 18 saves and a 2.47 ERA (12 ER/43.2 IP) in 45 relief appearances with the Cubs this season. Rondon did not require a rehab assignment as part of his return.
