Hunter will make a rehab appearance with High-A Charlotte on Tuesday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

This will be his first rehab appearance, and he will likely make a handful of appearances before rejoining the big-league club. He most recently looked sharp in a batting practice session Saturday.

Hunter (calf) looked sharp throwing batting practice Saturday but remains without a timetable for return, Marc Topkin of the Tampa Bay Times reports. "Now we have to be patient and see when he can get to running, covering off the mound, backing up bases," manager Kevin Cash said.

EDGE Analysis

The veteran reliever is progressing through each rehab step without setbacks, but as Cash indicates, the Rays will continue to take a diligent approach to his return. Hunter isn't expected back before early June in a best-case scenario, but that timetable could naturally extend out further if necessary.

Hunter (calf) threw a bullpen session Wednesday, his third since being placed on the disabled list, Marc Topkin of Tampa Bay Times reports.

EDGE Analysis

All signs indicate Hunter has been steadily improving throughout the rehab process, likely meaning he'll ramp up his activity over the next week via live batting practice. An early-June return remains probable at this point, barring any setbacks, and Hunter could be in line for extended usage due to injuries to fellow relievers Brad Boxberger and Xavier Cedeno.

Hunter (calf) threw his second successful bullpen session Monday and plans for another Wednesday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

The veteran reliever encouragingly emerged setback-free from his initial session on Saturday, allowing him to come right back Monday for a second go-around. If Wednesday's turn goes as well as the first pair of outings, Hunter will progress to throwing live batting practice next weekend.

Hunter (calf) is slated to throw his first bullpen session Saturday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

The veteran has been sidelined since April 22 with his calf injury, and is still projected to be several weeks away from returning. Hunter had been highly effective over his first 10 appearances, so his eventual return will certainly be a welcome development for a Rays relief corps that's been hit hard by injuries overall.

Hunter (calf) could be sidelined into June, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

The veteran reliever exited Saturday's game against Houston after straining his right calf attempting to cover first, and it now appears the injury could derail him much longer that previously thought. Hunter had been one of the pleasant bullpen surprises for manager Kevin Cash in the early going, generating a 1.08 ERA and 0.96 WHIP over 10 appearances.

Hunter (calf) was placed on the 10-day disabled list Sunday, Roger Mooney of the Tampa Bay Times reports.

EDGE Analysis

Hunter was removed from Saturday's game against the Astros after tweaking his calf while running to cover first base. It's currently unclear if he'll need more than the minimum 10 days to recover from his injury. Chih-Wei Hu has been recalled from Triple-A Durham to fill Hunter's void in the bullpen.

Hunter was pulled from Saturday's game due to calf tightness, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Further information regarding Hunter's condition should be available Sunday, however the team has said that a DL stint is not out of the question. Hunter pitched less than an inning in Saturday's game against the Astros and threw just nine pitches.

Hunter fired 1.1 scoreless innings in Thursday's 5-2 loss to the Blue Jays, striking out three of the four hitters he faced.

EDGE Analysis

Hunter put together his second consecutive strong outing to open the season, and he was particularly sharp Thursday. The veteran did it the hard way, striking out Josh Donaldson with Justin Smoak on third to end the seventh, and then whiffing Kendrys Morales and Troy Tulowitzki for two of his outs in the eighth. Hunter looks like one Rays' more prudent offseason additions through his first pair of appearance following a solid spring during which he generated a 2.70 ERA over 10 innings.

Hunter fired a scoreless ninth inning in Tuesday's 5-0 loss to the Yankees, allowing just one walk.

EDGE Analysis

The veteran reliever was added to the 40-man roster Saturday after a solid spring in which he generated a 2.70 ERA and nine strikeouts over 10 innings. Hunter projects to see plenty of work in the seventh and eighth innings this season and also notably brings some closing experience, having notched 16 saves in his eight-plus major league seasons.
