Manager David Bell said Castillo (shoulder) is "penciled in" to return from the 10-day injured list to start in the Reds' series opener Monday against the Brewers in Cincinnati, C. Trent Rosecrans of The Athletic reports.

EDGE Analysis

Castillo will likely be confirmed to make his season debut Monday once he completes a bullpen session over the weekend. Bell's comments on the right-hander's upcoming return came shortly after Castillo dominated in his third minor-league rehab start Wednesday with Triple-A Louisville. He worked 4.1 innings and tossed 76 pitches (48 strikes) in the outing, striking out seven while giving up zero runs on three hits and two walks. Castillo should be in line for about a 90-to-100-pitch workload when he returns from the IL next week.

Castillo (shoulder) made his third rehab start Wednesday with Triple-A Louisville, striking out seven over 4.1 scoreless innings while allowing three hits and two walks.

EDGE Analysis

Castillo tossed 48 of his 76 pitches for strikes in the start and generally steered clear of trouble during the afternoon. Given his workload and how effectively he pitched Wednesday, Castillo is likely to come off the 10-day injured list to make his next start with the Reds. He tentatively lines up to start Monday's series opener against the Brewers in Cincinnati, though it's possible the Reds extend him an extra day of rest before clearing him for his season debut.

Reds manager David Bell said Tuesday that Castillo (shoulder) will require two more rehab starts in the minors before returning from the 10-day injured list, Bobby Nightengale of The Cincinnati Enquirer reports.

EDGE Analysis

Castillo made his first rehab appearance Sunday with High-A Dayton, giving up an earned run on two hits and three walks while striking out four over 2.1 innings. After Castillo tossed 48 pitches in that outing, the Reds are targeting 60-to-65 pitches or four innings for him in his second rehab start, which will come Friday with Triple-A Louisville, according to Nightengale. Assuming he remains on a normal four days' rest schedule following his second and third rehab starts, Castillo would tentatively line up to make his season debut with the big club May 9 versus the Brewers in Cincinnati.

Castillo (shoulder) tossed 2.1 innings Sunday in his rehab start for High-A Dayton, giving up one earned run on two hits and three walks while striking out four.

EDGE Analysis

Castillo needed 48 pitches to retire seven of the 11 batters he faced in his first game action at any level since spring training. He pumped in 27 of his pitches for strikes Sunday, and the Reds will likely want to see him show improved efficiency while simultaneously upping his pitch count in his next rehab start. Castillo could move up to Triple-A Louisville for that outing, which would likely be his last before he comes off the 10-day injured list and slots into the Cincinnati rotation.

Castillo (shoulder) is scheduled to begin a minor-league rehab assignment Sunday, C. Trent Rosecrans of The Athletic reports.

EDGE Analysis

The 29-year-old threw 35 pitches during live batting practice Tuesday, and the next step in his rehab will be pitching in minor-league games. Castillo is expected to report to Triple-A Lousiville or High-A Dayton and be limited to about 50 pitches. He'll likely require two additional rehab starts after Sunday before returning from the injured list.

Castillo (shoulder) threw 20 pitches in a live batting practice session Friday and will have another such session on Tuesday, Bobby Nightengale of The Cincinnati Enquirer reports.

EDGE Analysis

Castillo doesn't yet have a schedule set to go on a rehab assignment, but it might occur shortly after Tuesday's session if all goes well. Given that Castillo hasn't pitched in any game action yet, he's likely going to need multiple rehab starts before getting activated.

Castillo (shoulder) is scheduled to throw live batting practice Friday, C. Trent Rosecrans of The Athletic reports.

EDGE Analysis

Castillo threw a bullpen session Tuesday and responded well, so he'll now progress to the next step of his throwing program. Assuming he continues to pitch without pain, Castillo should go on a rehab assignment soon and could return by late April or early May.

Reds manager David Bell said that Castillo (shoulder) checked out fine after throwing a bullpen session Tuesday, C. Trent Rosecrans of The Athletic reports.

EDGE Analysis

Castillo is scheduled to throw live batting practice this weekend in Los Angeles at some point during the Reds' four-game series with the Dodgers. If all goes well, Castillo could be sent out on a brief minor-league rehab assignment thereafter. The right-hander looks on track to return from the injured list at some point in late April or early May.

Reds manager David Bell said Castillo (shoulder) will play catch Thursday and is likely to throw a bullpen session over the weekend, Mark Sheldon of MLB.com reports.

EDGE Analysis

Cincinnati officially moved Castillo to the 10-day injured list Thursday, but the right-hander doesn't look like he'll reside there for a lengthy period to open the season. Though Castillo isn't on pace to make it back on the active roster in the minimum 10 days, Bell said that the Reds are optimistic the 29-year-old will be ready to go by late April. While Castillo and Mike Minor are on the IL, top prospects Hunter Greene and Nick Lodolo will hold down spots at the back end of the rotation.

Castillo (shoulder) landed on the injured list as expected Thursday.

EDGE Analysis

The move was reported back in late March, as Castillo has been delayed by a sore shoulder throughout the spring. His absence isn't likely to be a long one, as he's expected back in mid-to-late April, though he'll be on a pitch count for his first start or two.
