Lou Holtz heard about Michigan football coach Jim Harbaugh’s day with the Tigers on Wednesday. That wasn’t why he visited their camp Friday, but he couldn’t resist getting in a one-liner. “Obviously they don’t trust his decision-making, or he would’ve been on third,” Holtz said with a smile.

Joining the list of Giants who are being handled with care this spring, right-hander Johnny Cueto was scratched from his scheduled start Saturday against Texas.

Shelby Miller and Kenta Maeda, pitchers who figure prominently in their new clubs’ chances this year, make their respective debuts as starting opponents Saturday when the D-backs meet the Dodgers in a Cactus League game at Camelback Ranch-Glendale.

Who’s old? Not David Ross, who has been a good sport this spring as young Cubs Anthony Rizzo and Kris Bryant tease him about his age. Grandpa Rossy showed them how the game should be played when he turned a double play in the fourth inning during a 3-0 win against the Angels on Friday.

Astros shortstop Carlos Correa, who last year used Marc Anthony’s song, “Preciosa,” as his walk-up song, met the singer while he was in town to watch the Astros and Cardinals at Osceola County Stadium on Friday.

It was a “need-a-double-take” moment last week, Randal Grichuk peeking his head into the Cardinals’ clubhouse and urging his teammates to follow him to the multi-purpose room of the Spring Training complex. “Time for Pilates!” Grichuk exclaimed.

Delino DeShields and Shin-Soo Choo are well versed in their roles as table-setters atop the Texas batting order. Their job is to reach base and let the big boppers — namely Prince Fielder, Adrian Beltre and Mitch Moreland — do the rest.

Ian Desmond’s introduction to life as the Rangers’ left fielder was a moment he hopes he doesn’t relive very often this season. The first ball hit his direction during Friday’s 3-3 tie with the Dodgers was a towering home run — on which Desmond simply turned his back and trotted to the wall.

Munenori Kawasaki sparked the Cubs’ morning stretch Friday by singing karaoke to Aerosmith’s “I Don’t Want to Miss a Thing,” and he inspired players to wear headbands with Japanese sayings such as “Must Win” and “Fighting Spirit.”

A bubble of displeasure floated to the surface on Friday when the Mets renewed Jacob deGrom’s contract for $607,500 — $100,000 above the Major League minimum. deGrom was the only one of the Mets’ 25 pre-arbitration players who could not agree to terms on a new deal.
