Carlos Silva (heart) will make his second minor league rehab start with Single-A Peoria on Wednesday.

Silva is expected to throw approximately 70 pitches. Barring any setbacks, it should be enough to ensure his return from the disabled list. Silva is currently working his way back from undergoing a minor heart procedure earlier this month.

Carlos Silva (heart) is scheduled to begin a minor league rehab assignment on Friday with Single-A Peoria.

Silva had a minor surgical procedure Monday to correct arrhythmia. Cubs manager Lou Pinella said he anticipates re-inserting Silva into the team's rotation, but the team might also give some younger players a look. ''Depending on who we call up in September, we'll probably have to give some young pitcher a start,'' Piniella said, ''so we'll have to play this thing by ear.''

Carlos Silva was released from the hospital Monday after undergoing a minor cardiac ablation to remedy an irregular heartbeat.

He underwent the procedure today. That he was already released from the hospital and will begin a throwing program next week bodes better for his future than any statement about the operation being a success. The rotund pitcher has altered his arsenal this year and showed the best strikeout rate of his career after moving to the National League. His owners hope he returns quickly.

Carlos Silva allowed just one run over five innings in Monday's 5-2 win over the Astros.

The big right-hander gave up five hits and one walk while striking out four. This solid outing was much needed after Silva was hammered for 11 runs in 2 1/3 innings over his previous two starts. He's now 10-4 on the season and holds a 3.76 ERA and 1.22 WHIP. Silva has a tough matchup this weekend in Colorado.

The struggling Carlos Silva may have his next start pushed back in order to work on the side.

Carlos Silva will make his scheduled start Sunday despite a calf injury.

The right-hander might be limited to five innings, though, since manager Lou Pinella has plenty of bullpen arms at his disposal with a three-day break coming up. Silva won't make his first second half start until Monday the 19th, as Pinella wants to give Silva as much time as possible to get over his injury. Ryan Dempster, Ted Lilly, Randy Wells and Tom Gorzelanny will pitch the first four games after the break for the Cubbies.

Carlos Silva is questionable for Sunday's start against the Giants due to discomfort in his right calf, according to MLB.com's Carrie Muskat.

Earlier this week, Bob Nightengale of USA Today reported that Silva was bothered by some soreness behind his knee. In any case, Mitch Atkins would make the start if Silva can't go.
