Harrison is progressing in his recovery from a right ankle sprain and had been playing catch off flat ground from up to 90 feet as of Saturday, MLB.com reports.

EDGE Analysis

While the fact that Harrison hasn't been shut down from activity one week after landing on the injured list is an encouraging sign, the Giants still aren't counting on the 22-year-old lefty to rejoin the rotation until July. With all of Harrison, Blake Snell (groin) and Keaton Winn (elbow) going on the IL within the past three weeks, the Giants are left with Logan Webb and Jordan Hicks as the only healthy members of their season-opening rotation.

The Giants placed Harrison on the 15-day injured list Sunday with a right ankle sprain.

EDGE Analysis

Harrison had been scheduled to start Sunday's game against the Angels, but his ankle injury will prompt the Giants to go with an impromptu bullpen day for the series finale, with left-hander Erik Miller serving as the team's opening pitcher. The severity of Harrison's ankle sprain isn't clear, but he'll be eligible to return from the IL as soon as June 28. After getting off to a rough start to the season through his first five outings, Harrison had rebounded with a 2-2 record, 3.40 ERA, 1.33 WHIP and 44:17 K:BB in 50.1 innings across his subsequent nine starts.

Harrison allowed one run on four hits and no walks while striking out three batters over 6.1 innings in a no-decision against Houston on Monday.

EDGE Analysis

Harrison had just nine whiffs and three punchouts in the outing, but he kept the Astros off the scoreboard until the seventh frame. The left-handed hurler finished with his second straight quality start and allowed fewer than three runs for the first time since May 7. Harrison hasn't given up more than four earned runs in any of his 14 starts this season, though, helping him maintain a respectable 3.96 ERA despite a mediocre 1.33 WHIP and 68:22 K:BB across 77.1 innings.

Harrison dropped to 4-3 on the season in Tuesday's 8-5 loss to the Diamondbacks, allowing four runs (three earned) on eight hits and no walks while striking out five over six innings.

EDGE Analysis

Harrison worked a pair of clean innings before the Diamondbacks opened up the third with four consecutive hits, leading to three runs, and then tacked on an unearned run in the fourth. Despite giving up some hard hits early, Harrison was able to buckle down and complete six innings for the first time since May 7. He also managed to not walk a batter for the first time since April 26. The 22-year-old has now given up 20 hits over his last 11 innings, though that also comes with a 10:1 K:BB. Harrison will carry a 4.18 ERA, 1.39 WHIP and 65:22 K:BB into his next start, which projects to fall against Houston early next week.

Harrison (4-2) took the loss Wednesday against the Phillies, allowing four runs on 12 hits and a walk over five innings. He struck out five.

EDGE Analysis

Harrison's final line ultimately could've looked a lot worse, as he surrendered a career-most 12 hits. The 22-year-old southpaw's hit a rough patch of late, giving up three or more runs over five innings in each of his last four starts. Harrison's ERA is up to 4.15 through 12 starts (65 innings) this year with a 1.40 WHIP and 60:22 K:BB. He'll look to get on track in his next outing, currently lined up for early next week in Arizona.

Harrison came away with a no-decision in Friday's 8-7 comeback win over the Mets, giving up five runs (four earned) on six hits and two walks over five innings. He struck out six.

EDGE Analysis

The rookie southpaw got hit hard, serving up loud homers to J.D. Martinez and Mark Vientos in the fifth inning, and Harrison left the mound with the Giants down 5-2 before they once again rallied, becoming only the fourth team since 1900 to win three straight games that it had been trailing by at least four runs. Harrison has pitched into the sixth inning only once in his last five starts, and curiously the exception came at Coors Field. He'll take a 3.90 ERA, 1.30 WHIP and 55:21 K:BB through 60 innings into his next outing, which is scheduled to come at home next week against the Phillies.

Harrison (4-1) picked up the win Saturday versus the Rockies, yielding three runs on five hits and two walks over five frames. He notched four strikeouts.

EDGE Analysis

Harrison was originally supposed to start Friday but got pushed back a day, with the Giants indicating it was because they were keeping an eye on his workload. His velocity was down a bit Saturday and he had thrown only 79 pitches over his five frames before getting pulled. While not overly sharp, Harrison was still good enough against the Rockies to pick up his fourth victory of the season. While the left-hander's 3.60 ERA and 1.27 WHIP have been solid, he's been a bit of a disappointment from a strikeouts perspective with just 49 over 55 innings.

Harrison allowed three runs on three hits and five walks while striking out five over five innings in a no-decision versus the Reds on Sunday.

EDGE Analysis

Walks have become an issue for Harrison in May -- he's issued 12 of them over 17 innings across his last three starts while adding 14 strikeouts in that span. The Reds weren't fully able to capitalize Sunday, scraping together three runs in the first inning but leaving four runners on base over the next four frames before finding more luck against the Giants' bullpen. Harrison has allowed just four runs over his last 23 innings and now has a 3.42 ERA, 1.26 WHIP and 45:17 K:BB through 50 innings across nine starts this season. He's projected to make his next start at home versus the Rockies.

Harrison (3-1) earned the win over the Rockies on Tuesday, tossing seven shutout innings while allowing four hits and two walks. He struck out two.

EDGE Analysis

Harrison twirled another gem Tuesday night, this time in hitter-friendly Coors Field. He tossed a career-best seven scoreless frames and has now allowed just one run over his last 18 innings pitched. Harrison battled control issues in Triple-A, but he seems to have shrugged off any concerns thus far. Through eight starts, Harrison has gone at least six innings and issued two or fewer walks five times. He's now down to a 3.20 ERA, 1.22 WHIP and 40:12 K:BB in 45 innings and projects for a matchup at home against the Reds over the weekend.

Harrison allowed one run on three hits and five walks while striking out seven batters over five innings in a no-decision against Boston on Thursday.

EDGE Analysis

Harrison issued a season-high five free passes -- as many as he had handed out over six starts coming into the contest -- but managed to continuously get out of trouble, as none of the batters he put on base via walk came around to score. The southpaw thus managed to emerge with a no-decision, though his high pitch count of 95 offerings limited him to five frames and prevented him from picking up what could have been his fifth quality start of the campaign. Though Harrison has settled for a no-decision in each of his past two appearances, he's allowed just one run while fanning 14 batters over 11 frames during that span.
