Gregerson (hamstring) fired a scoreless second inning in High-A Palm Beach's 7-3 win over Jupiter on Saturday, recording two strikeouts.

EDGE Analysis

Gregerson followed new bullpen mate Greg Holland, who opened the game. The fact he got through his frame in crisp fashion is naturally an encouraging sign, although not altogether surprising given the caliber of competition. Gregerson is likely to make several more appearances at the minor-league level before being called up, and he's now projected for a setup-type role in the wake of Holland's signing.

Gregerson (hamstring) will make a rehab appearance at High-A Palm Beach on Saturday.

EDGE Analysis

Gregerson has been battling a mild hamstring strain since late March. He seems to be on schedule for a mid-April return. Once he's back in St. Louis, he'll be a setup man for new acquisition Greg Holland, who is also working his way up to speed with Palm Beach after signing with the Cardinals on Opening Day.

Gregerson (hamstring) threw a bullpen session Thursday, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

Assuming Gregerson's hamstring is OK when he's evaluated Friday, he should be cleared to head out on a minor-league rehab assignment with High-A Palm Beach. It's still unclear when he'll be ready to rejoin the big club, however, as the number of rehab appearances he'll make has yet to be determined. Gregerson is expected to slot into a setup role once healthy, with Greg Holland working as the team's closer.

Gregerson (hamstring) has been placed on the 10-day disabled list, retroactive to March 26.

EDGE Analysis

As expected, Gregerson will open the 2018 campaign on the shelf as he continues to work his way back from a strained hamstring. The Cardinals have yet to provide a timetable for his return at this point. With Gregerson sidelined, Dominic Leone is the favorite to work as the team's closer, while Tyler Lyons could also see save chances on a situational basis.

Gregerson (hamstring) will open the year on the 10-day disabled list, Joe Trezza of MLB.com reports.

EDGE Analysis

Manager Mike Matheny broke the news Saturday afternoon, which will likely grant Opening Day roster spots to John Brebbia and Mike Mayers in the Cardinals' bullpen. Dominic Leone is expected to take on the closing duties, though Tyler Lyons could also figure into the ninth-inning mix, especially with Gregerson sidelined. The team has yet to provide a timetable for the right-hander's return, but unless it's more than the mild hamstring strain that was announced, he should be back on the mound by mid-April.

Gregerson did not travel with the team for Friday's game against the Mets due to a mild hamstring strain, Joe Trezza of MLB.com reports.

EDGE Analysis

There has been no timetable provided by the team at this point but Gregerson's availability for Opening Day may be in jeopardy depending on the severity of this strain. Even though it's being classified as mild, the Cardinals will likely take it slow with the reliever, especially since he's been dealing with an oblique injury for the past couple weeks. Regardless of his status, Dominic Leone is expected to man the ninth-inning role for the Redbirds.

Gregerson (oblique) fired a scoreless ninth inning in Sunday's 10-0 Grapefruit League win over the Nationals.

EDGE Analysis

Gregerson was sharp in only his second outing of spring, and his return to action was a welcome sight with his most recent -- and only -- spring appearance having come back on March 3. While his chance of opening up the season as the clear-cut closer have reportedly taken a hit during his absence due to Dominic Leone's strong spring, Gregerson still projects for an ample late-inning role at a minimum in 2018.

Gregerson (oblique) emerged setback-free from Friday's 27-pitch bullpen session, Joe Trezza of MLB.com reports.

EDGE Analysis

It was the first official test of the oblique that has already cost Gregerson nearly two weeks. Given the positive outcome, he could return to game action as early as Sunday against the Nationals, although how he feels Saturday will be one of the most important factors with respect to whether that comes to fruition. "He looks healthy," Cardinals pitching coach Mike Maddux said. "It's all a matter of the bounce back now. How he feels tomorrow will be the tell."

Gregerson (oblique) will throw a live batting practice session Friday, Joe Trezza of MLB.com reports.

EDGE Analysis

If everything goes well, the obvious next step would be for Gregerson to get into Grapefruit League play. It seems that Dominic Leone has passed Gregerson as the most likely Cardinals reliever to open the season as the team's closer. If Gregerson can show he is healthy and Leone were to slip up, it could still be Gregerson who gets saves early this season, but he is no longer the preferred option for fantasy.

Gregerson (oblique) will throw a bullpen session in the coming days and could take the mound in a Grapefruit League game by early next week, MLB.com's Joe Trezza reports.

EDGE Analysis

Gregerson has been battling a mild oblique injury for almost a week now, and could potentially remain sidelined for the start of the 2018 season. He was able to play catch Tuesday and should be able to get a few spring games under his belt between now and Opening Day barring a setback during his upcoming bullpen. In the event that Gregerson needs more time to recover at the start of the regular season, expect Dominic Leone to take on the ninth-inning role in his absence.
