Harrison did not factor into the decision Tuesday, allowing two runs on five hits and one walk over 3.1 innings against the Phillies. He struck out five.

EDGE Analysis

The 22-year-old southpaw was greeted harshly in his MLB debut, as Bryce Harper took him deep to right for a first-inning, two-run homer Tuesday. However, Harrison demonstrated his strikeout potential, with each of the first five outs he recorded against Philadelphia coming via the punchout. The strikeouts come as no surprise given he led all of minor-league baseball with 14.5 K/9 prior to his promotion, but his control issues (6.4 BB/9) were the main culprit in limiting Harrison's overall production. He completed five innings just one time in his 21 minor-league starts this year. If he sticks around in San Francisco, the rookie will undoubtedly rack up big strikeout numbers, although his inefficiency and limited pitch counts suggest that quality starts and wins may be tough to come by. Harrison tentatively lines up to face the Reds at home early next week.

Harrison tossed three scoreless innings with one hit allowed, three walks and five strikeouts Thursday for Triple-A Sacramento.

EDGE Analysis

This was Harrison's best start of the year, but that's damning with faint praise, as he still walked a batter per inning and only recorded nine outs. On the season, he has 13 walks and 12 strikeouts and has not gone deeper than 3.1 innings.

Harrison was reassigned Tuesday to the minor-league side of Giants camp, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

Harrison had been lit up for eight earned runs through 3.2 innings of work this spring in Cactus League play, but he ranks as one of the top pitching prospects in all of baseball and could feasibly push to make his MLB debut in late 2023. He is 21 years old and doesn't turn 22 until August.

Harrison will begin the 2023 season in Triple-A Sacramento, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

The 21-year-old lefty spent the majority of last season with Double-A Richmond, where he put up a 3.11 ERA and 1.18 WHIP through 84 frames alongside a 13.61 K/9. Harrison has established himself as one of the best left-handed pitching prospects in baseball, and he could be in line to make his major-league debut sometime this season if he continues to perform at a high level in Triple-A.

Harrison made the start in Double-A Richmond's first playoff game Tuesday and lasted just three innings, striking out nine while allowing two runs on four hits and a walk.

EDGE Analysis

All things equal, it wasn't a terrible outing, considering that Harrison recorded every one of his outs via strikeout, but he did give up a trio of doubles while needing 71 pitches to navigate three frames. Harrison closed out the regular season for Richmond with a 3.11 ERA, 1.18 WHIP and 127:39 K:BB across 84 innings after averaging more than two strikeouts per inning alongside a 1.55 ERA in a 29-frame stint in High-A. Regardless of the returns in these playoffs, he's earned his place as one of the top pitching prospects in baseball.

Harrison has pitched 12 scoreless innings over his last three starts with Double-A Richmond, allowing just five hits in that span while posting a 17:7 K:BB.

EDGE Analysis

Harrison went six frames in the first of those three outings, but he was limited to three in the latter two -- presumably a function of the organization managing his innings. His walk rate has been noticeably elevated since he moved up to Double-A, but even so, Harrison's numbers since being promoted -- a 2.79 ERA, 1.12 WHIP and 74 strikeouts in 48.1 frames -- are nothing short of spectacular for a 20-year-old at that level. Harrison has been incredibly hard to hit, having given up three or fewer base knocks in eight consecutive starts now.

Harrison has allowed just one earned run over 11 innings spanning his last two starts for Double-A Richmond, posting a 17:7 K:BB in the process. All told, he has a 4.44 ERA, 1.41 WHIP and 39:15 K:BB in five starts since being promoted.

EDGE Analysis

Walks have obviously been an issue for the 20-year-old hurler since his promotion; he was significantly sharper with his command in High-A, but the higher level of competition in Double-A has clearly required an adjustment. Nonetheless, Harrison's certainly brought his bat-missing ability with him. He'll need to improve his strike-throwing to continue progressing toward San Francisco, but Harrison has a starter's profile and the benefit of pitching for an organization with an excellent track record of developing arms.

Harrison was promoted to Double-A Richmond on Tuesday, Melissa Lockard of The Athletic reports.

EDGE Analysis

Harrison has pitched extremely well this season with High-A Eugene, compiling a 1.55 ERA and 1.00 WHIP with an eye-popping 59 strikeouts over 29 innings in seven starts. The 20-year-old will now get the chance to face a higher level of competition with Double-A Richmond.

Harrison has put up a 21:3 K:BB alongside a 3.27 ERA and 1.00 WHIP across 11 innings spanning three starts so far this season for High-A Eugene.

EDGE Analysis

Last year, Harrison piled up both the strikeouts (14.3 K/9) but also the walks (4.7 BB/9) across 98.2 innings in Low-A, but the 20-year-old is showing far better control in the early going this season (though he did regress in his most recent outing). Harrison's already well regarded for his big fastball and sweeping slider, which likely give him a solid floor as a high-leverage reliever even if he doesn't ultimately make it as a starter. For now, though, he is on track to be a starter, and his stuff combined with the Giants' track record of developing pitchers certainly gives him the potential to become a good one. He's most likely still two or three years away from a potential MLB debut, though.
