Kerry Wood was back on the mound, right where the Chicago Cubs need him. Byung-Hyun Kim is headed to Colorado, the last place a struggling pitcher needs to be.

After missing three weeks because of a sore shoulder and stiff back, Wood threw 92 pain-free pitches to lead Chicago over the Colorado Rockies, 5-4, Wednesday in Mesa, Ariz.

“I felt great,” he said. “I felt like I could have gone more. It’s a good sign, considering the time I’ve missed.”

The Boston Red Sox hadn’t been pleased with Kim for a long time, so they traded him to Colorado and called the $10 million, two-year deal they gave him before the 2004 season “a mistake.”

The right-handed reliever with the submarine delivery was sent to the Rockies for 23-year-old left-hander Chris Narveson, who was optioned to Triple-A Pawtucket, and catcher Charles Johnson, who immediately was designated for assignment and released.

In other trades, Pittsburgh acquired backup catcher David Ross from the Los Angeles Dodgers for cash, and Baltimore sent left-hander Matt Riley to Texas for outfielder Ramon Nivar.
