Hess (2-1) picked up the win in Friday's 2-0 victory over the Rays, allowing four hits and three walks over 6.2 scoreless innings while striking out three.

EDGE Analysis

The rookie put together his most impressive performance to date in the majors, throwing 61 of 91 pitches for strikes and generating a solid 14 swinging strikes in stifling the Tampa offense. Hess lowered his ERA to a respectable 4.15 in the process, but he will face a tougher test in his next outing Wednesday at home against the Nationals.

Hess (1-1) allowed five runs on eight hits and two walks while striking out four across 4.2 innings Sunday as he took the loss to the Red Sox.

EDGE Analysis

Hess was bitten by the home run as he allowed all five runs on three long balls. In two starts for the Orioles this season, he's accrued a 6.75 ERA and 1.50 WHIP across 10.2 innings. After being called up from Triple-A Norfolk to make a spot start Sunday, it's uncertain if Hess will remain in the big leagues following a shaky outing.

Hess was recalled from Triple-A Norfolk prior to his Sunday start against the Red Sox, Eduardo A. Encina of The Baltimore Sun reports.

EDGE Analysis

Hess will have his work cut out for him in the second big-league start as he's set to face the potent Red Sox lineup at Fenway Park. Hess made his last start with the Orioles on May 12, allowing three runs over six innings against the Rays to pick up the win.

Hess will be recalled to start Sunday against the Red Sox, Roch Kubatko of MASN Sports reports.

EDGE Analysis

Miguel Castro was an option on the major league roster to get the start Sunday, but he had to pitch in mop-up duty behind Tanner Scott in the seventh inning of Saturday's loss. With that, the Orioles need a fresh arm and will turn to Hess. The 24-year-old righty picked up the win in his first major league start May 12 against the Rays, going six innings while giving up three earned runs. The Orioles have yet to announce a corresponding move to add Hess to the 25-man roster.

Hess (1-0) picked up his first career MLB win Saturday against the Rays, allowing three runs on six hits while striking out three batters across six innings.

EDGE Analysis

Hess was called up to start Game 1 of Saturday's doubleheader and pitched well in what was his major-league debut. He faltered early, allowing a three-run homer to Matt Duffy in the first inning, but settled down from there, blanking the Rays over the final five frames while allowing just two baserunners over that stretch. Hess was pitching on just three days of rest, so he was pulled after just 78 pitches -- 56 of which were strikes -- despite having retired 10 of the last 11 batters he faced. He'll head back to Triple-A Norfolk after serving as the Orioles' 26th man for the twin bill, but this quality effort could afford him another opportunity with the big club sooner than later, especially with Chris Tillman (back) on the shelf.

Hess will start Game 1 of Saturday's doubleheader against the Rays, Jon Meoli of The Baltimore Sun reports.

EDGE Analysis

Hess had a one-day stint with the Orioles in mid-April before returning to the minors, and will make his major-league debut Saturday. The 24-year-old has a 2.12 ERA and 1.08 WHIP with 29 strikeouts over 29.2 innings (six starts) for Triple-A Norfolk this season.

Hess was optioned to Triple-A Norfolk on Monday.

EDGE Analysis

Hess was called up Sunday to provide extra depth in the bullpen but was not needed. He'll return to Triple-A for now, though he's clearly on the shortlist of pitchers the Orioles will bring up when they need extra help, so it's likely he'll return at some point this season.

Hess was recalled from Triple-A Norfolk on Sunday.

EDGE Analysis

Hess allowed one run and struck out seven in his lone start at Triple-A this season. Look for him to offer some length out of the Orioles' bullpen before eventually heading back to Triple-A to continue to develop as a starter. Donnie Hart was optioned to Triple-A in a corresponding move.

Hess was optioned to Triple-A Norfolk on Tuesday, Roch Kubatko of MASN Sports reports.

EDGE Analysis

It appears Hess will report to Triple-A to open the season after spending the previous two seasons with Double-A Bowie. He posted a 3.85 ERA across 154.1 innings (26 starts) with the Baysox last season, and could be used as an emergency big-league starter at some point in 2018 if he holds his own following the jump to Triple-A.

Hess was added to the Orioles' 40-man roster on Monday to protect him from the Rule 5 draft.

EDGE Analysis

The 24-year-old righty logged a 3.85 ERA, 1.23 WHIP and 123 strikeouts in 154.1 innings at Double-A, and has now logged almost 300 innings at that level. He should head to Triple-A, and could serve as an emergency big-league starter now that he is on the 40-man roster. He has back-of-the-rotation upside.
