Pirates place rookie outfielder Esmerlyn Valdez on injured list with a left hamstring injury

The Pittsburgh Pirates have placed rookie outfielder Esmerlyn Valdez on the 10-day injured list due to a left hamstring strain, effectively ending his first professional season. The 22-year-old was placed on the list after injuring himself while running to first base during Friday's 12-2 loss to the Chicago Cubs. Valdez had made his major league debut on May 22 against Toronto and had batted .235 with 17 home runs and 47 RBIs in 71 games prior to his injury.

He returned to the Pirates' roster on Saturday with the recall of outfielder Ronny Simón from Triple-A Indianapolis. Simón, who has batted .281 with two RBIs in 10 games, was activated from the injured list.
