6/28 John Grabow update
John Grabow will go on the disabled list Tuesday after re-injuring his left knee and may be out for an extended period. The lefty entered Monday’s game against the Pirates in the seventh and retired the first batter, then gave up an infield single to Ronny Cedeno. Paul Maholm squared to bunt on a 1-1 pitch, and Grabow finished the pitch awkwardly. Athletic trainer Mark O’Neal went to the mound and Grabow immediately headed to the clubhouse.
“It’s pretty bad,” Grabow said. “It’s something I thought I could pitch through and it got worse. I’ll go get it checked out [Tuesday].”
Grabow has received a cortisone shot already this season in the knee and was on the disabled list from May 31-June 15 because of it. In his last outing June 24, he gave up one hit over two innings against the Mariners.
The Cubs’ bullpen has been busy after Carlos Zambrano’s abbreviated outing on Friday. Right-hander Jeff Stevens will be added on Tuesday as Zambrano is moved to the restrictted list. They will add another pitcher to fill Grabow’s spot on the 25-man roster as well.
If the Cubs opt for a left-hander, it could be James Russell, who began the season with the big league team. Russell has given up seven runs on 11 hits and four walks over 11 innings in five games with the Iowa Cubs, striking out 10. Left-hander John Gaub has a 4.33 ERA in 27 games with the Iowa Cubs, serving up 13 earned runs on 24 hits and 16 walks over 27 innings while striking out 37.
If the Cubs opt for another right-hander, Jeff Samardzija is an option. He has a 1.88 ERA in 20 games, including three starts at Iowa. He’s given up eight earned runs on 24 hits and 22 walks while striking out 33 in 38 1/3 innings. He has started in three of his last four outings but that change in assignment was because of injuries or roster moves. Right-handers were batting .173 against Samardzija while lefties were hitting .189.
