Injured shortstop Tatis works out in center field for the Padres

All-Star shortstop Fernando Tatis Jr. of the San Diego Padres spent about an hour shagging fly balls in center field Friday, leading to some intrigue about what position he’ll play when he returns from his latest shoulder injury.

Tatis smoothly covered a lot of ground, leaped to rob some teammates of batting practice home runs and threw a few balls to kids in the stands.

As he shagged balls, Tatis received tips from members of the coaching staff.

Asked if he was intentionally working in center field, Tatis said: “Moving out there a little bit and just see what’s going to be the best for the team.”

Tatis partially dislocated his left shoulder sliding awkwardly into third base on

July 30 and was placed on the 10-day injured list the next day. It was the third time he left a game this year after partially dislocating his left shoulder and the second time he went on the IL with the injury. He also left two spring training games after injuring the shoulder.

Athletics

Center fielder Ramón Laureano was suspended for 80 games without pay by the commissioner’s office Friday

after testing positive for a performance-enhancing substance.

The commissioner’s office said Laureano tested positive for Nandrolone in violation of Major League Baseball’s Joint Drug Prevention and Treatment Program. Suspension is immediate.

“I would never knowingly ingest any banned substance and put the game that I’ve loved all my life at risk. When I found out that I tested positive for Nandrolone,

I was shocked,” Laureano said in a statement released by the players union.

Laureano, 27, from the Dominican Republic, is hitting .246 with 14 homers and 39 RBIs in 88 games this season.

Cubs

Chicago placed five-time Gold Glove outfielder Jason Heyward on the 10-day injured list Friday because of inflammation in his left index finger.

Manager David Ross said the finger has been bothering Heyward for “a pretty good bit” and he aggravated it taking batting practice at Colorado this week. Heyward is batting .198 with 6 homers and 22 RBIs.

The Cubs also called up outfielder Greg Deichmann from Class AAA Iowa. He was acquired July 26 from Oakland in the deal that sent reliever Andrew Chafin to the Athletics.
