Robertson (elbow) threw about 20 pitches in a bullpen session Sunday, Meghan Montemurro of The Athletic reports.

EDGE Analysis

It's Robertson's first bullpen session since he landed on the injured list with the flexor strain in mid-April, and he still has significant work to do in building up his velocity. The 34-year-old has another session scheduled for Wednesday, and if all goes well, he could return to the Phillies toward the end of July.

Robertson (elbow) could throw a light bullpen session Wednesday, Scott Lauber of The Philadelphia Inquirer reports.

EDGE Analysis

Robertson has been playing catch for nearly two weeks, but reports from just two days ago suggested that he was at least 10 days away from throwing a bullpen session. It appears that he may be several days ahead of that schedule, but given that he's already been out for over two months, it's hard to see him returning until after the All-Star break.

Robertson (elbow) could throw off a mound in 10-12 days, Matt Breen of The Philadelphia Inquirer reports.

EDGE Analysis

He has been playing catch, but throwing off a mound will represent a big step in his rehab. If he gets on a mound in early July, we could be eyeing an activation after the All-Star break.

Robertson (elbow) played catch Tuesday, Matt Gelb of The Athletic reports.

EDGE Analysis

This is an encouraging development for Robertson, who had been shut down from throwing for nearly a month prior to Tuesday's round of catch. The veteran reliever has been sidelined since April 15, so he'll need plenty of time to get back up to speed before the Phillies feel comfortable activating him. As such, a timetable for his return likely won't emerge until he ramps up his throwing program.

Robertson (elbow) is close to beginning a throwing progression, Matt Breen of The Philadelphia Inquirer reports.

EDGE Analysis

Robertson originally wasn't expected to resume throwing until mid-June, so this is certainly welcomed news for the Phillies and fantasy owners alike. Given the length of his absence -- Robertson has been on the shelf since April 15 -- the veteran right-hander will need plenty of time to get back up to speed. That said, manager Gabe Kapler noted a return before the end of June is "not out of the question" for Robertson.

Robertson (elbow) was transferred to the 60-day injured list Saturday, Meghan Montemurro of The Athletic reports.

EDGE Analysis

This is strictly a bookkeeping move that allows the Phillies to purchase the contract of J.D. Hammer. Robertson is not expected to resume throwing until at least mid-June.

Robertson (elbow) will not throw for three weeks, Matt Gelb of The Athletic reports.

EDGE Analysis

Robertson visited Dr. James Andrews on Monday, who recommended the veteran right-hander rest for a few weeks before resuming a throwing program. The 34-year-old has been sidelined since mid-April with a right flexor strain; while he remains without a timetable for his return, this recent setback suggests Robertson won't be ready to return until the end of June or beginning of July, at the earliest.

Robertson (elbow) played catch for the first time since suffering his right flexor strain Friday, Scott Lauber of The Philadelphia Inquirer reports.

EDGE Analysis

Robertson has been out since mid-April. He doesn't yet have a timeline for his return, but he doesn't appear to be particularly close as he's yet to get back on a mound.

Robertson (elbow) has yet to be cleared to throw, Scott Lauber of The Philadelphia Inquirer reports.

EDGE Analysis

Robertson has already been out over two weeks with a right flexor strain. The issue was considered Grade 1, but it doesn't sound as though he's particularly close to returning.

Robertson was diagnosed with a Grade 1 flexor strain in his right elbow Tuesday, Matt Breen of The Philadelphia Inquirer reports.

EDGE Analysis

Robertson landed on the 10-day injured list Monday with what was originally described as elbow soreness, but was clarified via an MRI. The 34-year-old will be shut down from throwing for a few days and then will be re-evaluated by the Phillies.
