Yates returned to Pittsburgh for further tests
• Reliever Tyler Yates returned to Pittsburgh today for further tests on his bothersome right elbow that flared up during Tuesday's simulated game. "I was super sore," Yates said on Tuesday night. Manager John Russell said it may be as long as a week before they have a diagnosis. "We thought he was making very good progress. You can't mess around with a pitcher's arm. We've got to make sure we find out what's going on."
• The day the Pirates' farm system returned one prospect from injury, they lost another. Double-A Altoona outfielder Jose Tabata came back from a six-week absence with a hamstring injury, but Triple-A Indianapolis third baseman Neil Walker will miss 3 to 5 weeks with a knee injury. Pirates director of player development Kyle Stark said Walker, who also has a dislocated pinky finger, has no structural damage. Tabata left Altoona's game with cramping and is day-to-day.
• First-base coach Perry Hill still doesn't know why he was ejected from Tuesday night's game after arguing a blown call on Delwyn Young's grounder in the eighth inning. Hill said it was the first time he was ejected from a game in 25 years in pro baseball, including 16 in the majors. "I didn't cuss and I didn't say the word 'You,'" Hill said. "I didn't say anything disrespectful. It's ridiculous. It's uncalled for. I hope they do fine me because I will appeal it. They expect you to be an unemotional cigar store Indian. I can't help that I got involved in the game. If I do it in a respectful manner, once every 16 years I should be able to voice my opinion."
