Extra bases

• Top prospect Javier Baez is projected as the starting shortstop at Triple-A Iowa but will get some playing time at second base in Cactus League games, beginning next week, Cubs manager Rick Renteria said Wednesday.

"We want to still be able to see him work and play at different positions," Renteria said. "We still haven't gotten him over at second base. We plan on doing it Monday or Tuesday. We'll go from there, maybe working him at third."

Baez has been working with infield coach Gary Jones at second and third.

Jason Hammel and Eric Jokisch will face Minor Leaguers on Thursday, which is an off-day for the Cubs, so they can stay on schedule. Hammel has made one Cactus League start last Saturday against the Reds, and gave up two hits over three innings. The right-hander admitted he had a few butterflies before the game, his first with the Cubs.

• Sunday's Cubs game against the Indians in Mesa will be telecast on Comcast SportsNet and will be entirely commercial free. According to a Comcast spokesman, the broadcast will feature interviews and features on players and coaches. The broadcast will begin at 3 p.m. CT.

• The ninth Annual "Race to Wrigley" 5k will be held April 12 at Wrigley Field. Voted "Best 5k in the Midwest" in 2013 by Competitor magazine, last year's event drew approximately 6,000 runners and raised more than $300,000 for Cubs Charities and the Ann & Robert H. Lurie Children's Hospital of Chicago.

The top fund-raising team and individual fund-raiser will receive tickets to the April 22 Cubs game against the Diamondbacks and be recognized in a pregame ceremony. Anyone who raises more than $1,000 will have the opportunity to run a post-race victory lap around the ballpark's warning track.
