• Rob Biertempfel of the Pittsburgh Tribune reports:

• The following players threw bullpen sessions on Tuesday: Charlie Morton, Brian Burres, Fernando Nieve, Chris Resop, Sean Gallagher, Tony Watson, Cesar Valdez, Tyler Yates, Jeff Karstens, Justin Thomas, Brad Lincoln, Chris Leroux, Daniel McCutchen, Ramon Aguero, Daniel Moskos and Bryan Morris.

• Right-handed pitcher Kevin Hart threw a long toss program on Tuesday before the team workouts. Hart had been shut down for 10 days and given a cortisone shot to help reduce inflammation in his surgically-repaired shoulder.

“Everyone that I’ve talked to who had the surgery says it is normal to have this type of issue,” Hart said. “They seem to think that it’s something that 10 days off could really resolve. It sounds really simple to think about, but when you don’t throw for four months and then start cranking it up, there are going to be some times when some tightness starts creeping in.”

Hart remains optimistic that he will be able ready by opening day.

• Left-hander Scott Olsen has thrown off the mound three times, his fourth session is scheduled on Wednesday. It’s reported that he has had no discomfort with his shoulder thus far.

“I’m hoping that everything stays healthy and that we can progress in the right direction,” Olson said. “We haven’t had any setbacks. No issues. It’s early, and we’re taking the proper steps and precautions that we need to take.”

• Right-hander Brad Lincoln has reported to spring training several pounds lighter this year. He spent the offseason going through some tough conditioning work.

Pitching coach Ray Searage has said that he would not be forcing any new mechanical changes on Lincoln moving forward. He also said Lincoln’s mechanics are back to where they need to be.
