7/23 Extra, extra bases
* With Mike Olt optioned to Triple-A Iowa, Luis Valbuena will get the majority of playing time at third base, manager Rick Renteria said. Valbuena made his 51st start at third on Wednesday; Olt had started 47 games at third.
* Olt will play first base and be the designated hitter while at Iowa. He was batting .139 in 72 games, but did lead all NL rookies with 12 home runs. He also has struck out 84 times in 187 at-bats.
“He acknowledged he’s gotten into a few bad habits at the plate, and bad habits that he couldn’t break out of at the big league level,” Theo Epstein said Wednesday. “I think playing every day down there will be good for him.”
* Cubs pitcher Kyuji Fujikawa, on a rehab assignment with Triple-A Iowa, struck out two of the three batters he faced Wednesday. Fujikawa, who had Tommy John surgery in June 2013, threw 14 pitches, nine for strikes, in his second outing with the team.
* Manny Ramirez, a player/coach at Triple-A Iowa, was placed on the disabled list Wednesday with a right calf strain. Ramirez pinch-hit on Wednesday and was batting .176 (6-for-34) in 11 games with the Minor League team.
