Tillman (back) is slated to make a start for High-A Frederick -- the fifth of his current rehab assingment -- on Tuesday, Eduardo A. Encina of The Baltimore Sun reports.

EDGE Analysis

Tillman's back checked out fine during a 45-pitch bullpen session Sunday, so he'll be ready what could be his final rehab start prior to being activated from the 10-day disabled list. The right-hander covered six innings in his last outing for Triple-A Norfolk and said he wants to work into the seventh or eighth inning Tuesday. If all goes according to plan, Tillman would likely be ready to rejoin the Orioles as soon as Sunday, though it's more likely the big club waits until after the All-Star break to reinstate him.

Tillman (back) will start again for Triple-A Norfolk on Thursday, Jon Meoli of The Baltimore Sun reports.

EDGE Analysis

Tillman hasn't gotten out of the fourth inning in any of his rehab starts, so it's no surprise that he'll make at least one more. He had an ugly 10.46 ERA in seven starts at the major-league level prior to his injury, so it's not clear that the Orioles will want him back on the roster any time soon, let alone in the rotation.

Orioles manager Buck Showalter said he wasn't certain where or when Tillman (back) would make his next rehab start after the right-hander was roughed up Saturday for five runs on eight hits and a walk over 3.1 innings for Triple-A Norfolk, Jon Meoli of The Baltimore Sun reports. "It didn't look very good statistically," Showalter said of Tillman's latest rehab outing. "I probably know the same thing [about Tillman's next step] that y'all do at this point."

EDGE Analysis

Tillman has already made three rehab starts and is about halfway through the 30-day rehab window pitchers are allotted under MLB rules. With Tillman having failed to escape the fourth inning in any of his minor-league outings thus far, it's almost certain that he'll need another start or two on the farm before the Orioles would consider bringing him off the 10-day disabled list. Tillman posted a 10.46 ERA and 2.21 WHIP in seven starts prior to hitting the DL and hasn't noticed dramatically better results in the minors, so the Orioles may be reluctant to insert him back into the big-league rotation once he's activated.

Tillman (back) is scheduled to make his third rehab start at Triple-A Norfolk on Saturday, Rich Dubroff of PressBoxonline.com reports.

EDGE Analysis

Tillman made the second start of his rehab assignment for Low-A Delmarva on Monday, covering 3.1 innings and tossing 62 pitches in that outing. The Orioles probably want to see Tillman build up to around 80-to-90 pitches and find success against higher-level minor-league competition before deeming his ready to return from the DL, so the right-hander will head to the International League for a stiffer challenge. It seems likely that Tillman will be in store for at least one additional start in the minors beyond Saturday's outing prior to being reinstated to Baltimore's active roster.

Tillman (back) made his second rehab start Monday for Low-A Delmarva, covering 3.1 innings and giving up two runs on four hits and one walk while striking out three.

EDGE Analysis

Tillman tossed 62 pitches (37 strikes) Monday and will likely need to up his count to the 80-to-90 range before the Orioles entertain activating the right-hander from the 10-day disabled list. Considering Tillman had posted a 10.46 ERA and 2.21 WHIP in 26.2 innings prior to landing on the DL in May with a lower-back strain, he's far from a lock to regain a rotation spot once he's activated.

Tillman (back) is expected to take the mound with Low-A Delmarva on Monday for his second minor-league rehab appearance, Eduardo A. Encina of the Baltimore Sun reports.

EDGE Analysis

Tillman made his first rehab start with short-season Aberdeen on Wednesday, which went by without any problems. The right-hander will build up his arm during Monday's anticipated outing, tossing approximately four innings or 60 pitches. Expect Tillman to require at least one more minor-league start following Monday's appearance before returning to Baltimore.

Tillman (back) will begin a minor-league rehab assignment with short-season Aberdeen on Wednesday, Rich Dubroff of PressBoxonline.com reports.

EDGE Analysis

Tillman has been on the disabled list since May 11 with a lower-back strain. Given the length of his absence, he'll likely need to make multiple rehab starts before being cleared to rejoin the Orioles. Tillman struggled to a 10.46 ERA through seven starts prior to landing on the shelf, so he'll need to prove his effectiveness once healthy before being trusted.

Tillman (back) could head to short-season Aberdeen for a rehab assignment next week, Roch Kubatko of MASN Sports reports.

EDGE Analysis

Tillman has been sidelined with a lower-back strain since May 11. His results were shockingly poor before the injury, as he posted a 10.46 ERA, a 9.5 percent strikeout rate and a 12.4 percent walk rate. That comes on the heels of the 7.84 ERA he posted in 93 innings last season. He will certainly have to prove his effectiveness when he returns from injury before fantasy owners will have any reason to trust him even as a streaming option.

Tillman (back) has been throwing bullpen sessions at the Orioles' spring training facility in Florida, Roch Kubatko of MASN Sports reports.

EDGE Analysis

Tillman is inching closer to heading out on a minor-league rehab assignment, which would mark the final step in his recovery from a lower-back strain that has kept him sidelined since May 11. He'll need to do more than prove his health while on his rehab assignment; manager Buck Showalter said the 30-year-old will need to produce serviceable results in the minors before the Orioles feel comfortable bringing him back. "He'll go out on rehab and take some starts there and he's going to have to show us not only that he's healthy, but he's doing something different than he was doing here before he left," Showalter said. "I feel confident that he's going to be able to do that.

Tillman (back) threw a 35-pitch bullpen Tuesday, Roch Kubatko of MASN Sports reports.

EDGE Analysis

Tillman continues to progress, as he threw for the first time since the injury Sunday and he's since progressed to a bullpen session. The Orioles will likely assess the injury following his latest throwing session in order to determine when he can begin a rehab assignment.
