2025 Fantasy Outlook
During his days in the minors when he became a top prospect, Harrison posted an ugly 12.3 percent walk rate but also a whopping 37.4 percent strikeout rate. Both of those numbers have come way down in the majors, with the lefty issuing walks at just a 7.8 percent clip but also fanning batters at a pedestrian 22.5 percent rate. Harrison's velocity also dipped in 2024 across the board and was down even more from August on when he posted a 7.76 ERA over six starts before he ended the season on the injured list with shoulder inflammation. Because it gets so much horizontal movement after he dropped his arm slot, Harrison's four-seamer still played well in spite of the lesser velocity, with the pitch earning a plus-seven Run Value. That said, the profile on the whole doesn't look as exciting as it did a year ago. Read Past Outlooks

Works five scoreless in win
Harrison (1-1) got the win after throwing five innings of shutout ball in Friday's 2-0 win over the Marlins. He allowed one hit, walked three and struck out five.
ANALYSIS
In his second start of the season since transitioning from the bullpen, Harrison had a longer leash and took advantage of it, working five shutout innings on just 80 pitches. In his two starts (nine innings), he's allowed just two runs with nine strikeouts. With Justin Verlander (pectoral) on the way back from the injured list, the 23-year-old Harrison might not get the chance to start again in the immediate future, but he's made a strong case to be the team's choice to make spot starts should injuries strike the Giants' rotation again.

Past Fantasy Outlooks
2024
2023
2022
Harrison walked three or more batters in 11 of his 20 starts at Triple-A, where automated balls and strikes may have increased walk rates relative to when humans are calling the game. He walked at least one batter but no more than two batters in all seven of his big-league starts, which lends credence to the theory that he may have less of a control issue when the human element is involved. Harrison always missed bats at an elite clip in the minors, with strikeout rates north of 35 percent at every stop. However his propensity to walk batters has held him back at times. The gap between his walk rate at Triple-A (16.3 percent) and the big leagues (7.5 percent) is essentially the difference between a pitcher destined for relief and a pitcher who comfortably projects as a starter. The 6-foot-2 southpaw was the third-youngest pitcher to make five-plus starts in the majors (only Eury Perez and AJ Smith-Shawver were younger), so it's fair to expect further skill development in the coming years for Harrison, who won't turn 23 until August. He is a flyball pitcher (26.8 GB% in the big leagues), but he has a good home park for that approach, as Oracle Park has the third-lowest home run park factor, per Baseball Savant's 3-year rolling average. He should make the rotation out of spring training, but a hamstring injury limited him to 102.1 innings, so the Giants may cap him at around 150 innings in the regular season.

Latest Fantasy Rumors

In mix for rotation spot
Harrison is a candidate to enter San Francisco's rotation after Justin Verlander was placed on the injured list due to a pectoral injury Thursday, reports Alex Pavlovic of NBC Sports Bay Area.
ANALYSIS
Harrison was called up in early May after missing out on the Opening Day rotation, and he's pitched well in four apperarances with a 3.38 ERA, 0.94 WHIP and 7:3 K:BB over 5.1 innings. The left-hander might be limited to about 50 pitches if called upon to start Saturday in Washington. Harrison had a 4.56 ERA over 24 starts in the majors last season, which was a decent showing for his first full season in the big leagues.
