Heston, who underwent shoulder surgery last summer, hopes to be fully healthy by January and hold a showcase for MLB teams ahead of spring training, Henry Schulman of the San Francisco Chronicle reports.

EDGE Analysis

After being released from the Giants' Double-A affiliate at Richmond last July, Heston didn't sign with another organization while on the mend from surgery. Given that he'll be 32 years old in April and had modest career numbers at the MLB level prior to requiring the major arm operation, Heston may have settle for a minor-league deal even if he looks good during his showcase.

Heston (undisclosed) made his fifth rehab appearance Tuesday for one of the Giants' rookie-level Arizona League affiliates, tossing a scoreless inning.

EDGE Analysis

Heston opened the season at Triple-A Sacramento, covering 3.1 innings in an April 9 start. He has been sidelined with the injury ever since, though he appears to be closing in on a return from the 7-day disabled list after beginning his rehab assignment June 20.

Heston agreed to a minor-league contract with the Giants on Wednesday, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

Heston spent the 2017 season bouncing around between a trio of organizations, finally finishing the campaign with the Twins' Triple-A affiliate. The 29-year-old will return to San Francisco, where he spent the first eight years of his career, up until last season. In total, he's pitched in 41 major-league games but only appeared in seven during the last two seasons, and will likely begin this upcoming year at the Triple-A level while serving as organizational depth.

Heston (shoulder) was activated from the 7-day DL at Triple-A Rochester on Wednesday, Brandon Warne of ZoneCoverage.com reports.

EDGE Analysis

He pitched five innings for the Twins' GCL team on Monday, clearing the final hurdle on his road back from a bout of shoulder tendinitis. Heston has posted a 7.63 ERA with Rochester, and he's mostly struggled with other affiliates this season. Further, the 29-year-old is not on the 40-man roster, so he will need to finish strong over the rest of August to have a chance at a September callup.

Heston heads to the minor-league DL with right shoulder tendinitis, Brandon Warne of Zone Coverage reports.

EDGE Analysis

Heston made just one appearance with the Twins after getting claimed by the team in early June. Since then, the 29-year-old has been sent down, DFA'd and roughed up a few times with Triple-A Rochester. It is unlikely that Heston resurfaces in the majors this season, and will be out for the foreseeable future while he recovers from this injury.

Heston was designated for assignment Friday.

EDGE Analysis

Heston was originally thought to be an option to make a spot start in Saturday's doubleheader with the Indians, but after being bypassed for the start by Adam Wilk, Heston will end up being the roster casualty to allow Wilk to make said start. Heston has plenty of MLB experience to his name, which could make him an attractive option to other teams while he's exposed to waivers.

Heston could be recalled to start one of the game's in Saturday's doubleheader with the Indians, Brandon Warne of ZoneCoverage.com reports.

EDGE Analysis

Heston, a recent waiver claim, was sent back to the minors on Monday, but he could head back to the big leagues to start Saturday now that Hector Santiago (shoulder) is unlikely to be ready to go by then. The right-hander has spent much of his career as a starter and is only a couple years removed from a season where he posted a 3.95 ERA in the Giants' rotation.

Heston was optioned to Triple-A Rochester on Monday, Brandon Warne of ZoneCoverage.com reports.

EDGE Analysis

After being claimed off waivers last week, Heston made his Twins debut Sunday against the Giants, tossing a scoreless inning in relief. Since the Twins have a few bullpen arms capable of covering multiple innings when necessary, the team didn't have a need to carry an extra long reliever, so Heston will head back to the minors to make room for shortstop Jorge Polanco (personal), who was activated from the bereavement list Monday in a corresponding move.

Heston was claimed by the Twins, and will be in Seattle for Minnesota's game Wednesday night, Phil Miller of the Star Tribune reports.

EDGE Analysis

Heston was recently picked up off waivers by the Dodgers after being designated for assignment by Seattle in late May, and now the right-hander finds himself with the Twins. He has only seen the mound twice this season, allowed a combined 11 earned runs off 14 hits over the course of 5 innings. The 29-year-old threw a no-hitter two years ago, but will be fortunate to latch on in a relief role with Minnesota this season.

Heston was claimed off waivers by the Dodgers on Friday, Andy McCullough of the Los Angeles Times reports.

EDGE Analysis

Heston was designated for assignment by the Mariners on Wednesday, but the Dodgers were quick to swipe him off waivers. The right-hander is a long way from his breakout season in 2015, but he has proven to be a serviceable starter in the minors this season, sporting a 3.41 ERA through six starts with Seattle's Triple-A affiliate. He'll likely act as organizational pitching depth, although he could move to the big leagues if injuries continue to plague LA's pitching staff.
