The Chicago Cubs today activated right-handed pitcher Koji Uehara off of the 10-day disabled list and added catcher René Rivera to the 25-man roster. In corresponding roster moves, left-handed pitcher Rob Zastryzny and catcher Victor Caratini have been optioned to Triple-A Iowa.
Both Uehara and Rivera, who will wear uniform number seven, will be available for the Cubs this afternoon as they conclude their three-game series against the Toronto Blue Jays at Wrigley Field.

Behind the plate, Rivera has thrown out 10 of 31 runners attempting to steal this season, a 32.3 percent success rate, which would tie for third-best in the National League if he had enough games played to qualify. His success rate this year mirrors his career totals, as he has thrown out 97 of 300 runners attempting to steal, 32.3 percent.
Zastryzny, 25, has made one appearance with the Cubs this season (4.0 IP, 3 ER). He is 1-2 with one save and a 6.57 ERA (27 ER/37.0 IP) in 12 appearances, five as a starter, with Iowa this season.
Caratini, 24, is batting .268 (11-for-41) with three doubles, one homer and two RBI in 17 games with the Cubs this season. With Iowa, he is hitting .344 (94-for-273) with 24 doubles, 10 homers and 59 RBI in 76 games.
