CINCINNATI -- The Cubs will fill Jeff Samardzija's and Jason Hammel's spots in the rotation with Dallas Beeler and Kyle Hendricks, who are scheduled to start Wednesday and Thursday, respectively, against the Reds.
The Cubs delayed announcing their rotation for the final two games of the four-day, five-game series against the Reds because they were uncertain about the weather. Rain delayed Monday's game by 21 minutes, but they were able to finish.
Samardzija and Hammel were traded Saturday to the Athletics, and the options included lefty Chris Rusin, who joined the team Saturday and pitched 3 2/3 innings in relief.
Tsuyoshi Wada will be added as the 26th man for Tuesday's doubleheader, and start the night game. Travis Wood will start the first game.
Beeler made his Major League debut at Wrigley Field on June 28 against the Nationals, and gave up one unearned run on four hits over six innings. Hendricks, acquired from the Rangers in the 2012 Ryan Dempster trade, was 10-5 with a 3.59 ERA in 17 starts at Iowa. Thursday will be his Major League debut.
