Giants' Pitchers Fantasy Baseball Preview | Logan Webb, Ryan Walker, Justin Verlander, Kyle Harrison, Robbie Ray and More

Let's continue our MLB team fantasy previews with the San Francisco Giants. We'll start by discussing the team's pitchers - check back for the hitter writeup.

We've covered the Athletics (hitters and pitchers), Pittsburgh Pirates (hitters and pitchers), Seattle Mariners (hitters and pitchers), Colorado Rockies (hitters and pitchers), Tampa Bay Rays (hitters and pitchers), Atlanta Braves (hitters and pitchers) and Chicago White Sox (hitters and pitchers) already.

Top Fantasy Pitchers

A few of the Giants on the Average Draft Position list are pitchers.

Logan Webb leads the way, going at pick 72.71 on average. Ryan Walker is up next at pick 108.65. Justin Verlander and Robbie Ray are late-round options.

Webb will power the Giants' starting rotation for another season. He's made over 30 starts in three straight seasons.

In 33 starts in 2024, Webb went 13-10. He had a 3.47 earned run average and 172 strikeouts over 204 2/3 innings. Webb isn't a huge strikeout guy, but with at least 192 1/3 innings in three straight years, he can eat innings and post good ERAs.

There's no reason to expect Webb to fall off in his age-28 season. He's a solid No. 2 fantasy starter, but an even better third or fourth guy. Don't let his “lack” of strikeouts fool you, because if he gets in over 200 innings again, there will be enough strikeouts to make him a good fantasy option in point or category leagues. Webb has a safe fantasy floor, and I like him right around his ADP.

Walker emerged as an elite reliever in 2024. He eventually took over the closer role, and looks to be the favorite to win that role again for 2025.

In 76 games last season, Walker went 10-4 with a 1.91 ERA and 10 saves. He struck out a whopping 99 batters over 80 innings.

Walker is a good fantasy reliever even if he's not closing. He could be in contention for the top fantasy closer spot if his ERA remains under 2 and he earns 25+ saves. Don't sleep on Walker this season.

Verlander's best days are behind him, but he's still a pretty solid fantasy option.

In 17 starts with the Astros last season, Verlander went 5-6 with a 5.48 ERA. He struck out 74 batters over 90 1/3 innings. He fared better in 27 starts in 2023, going 13-8 with a 3.22 ERA and 144 punchouts over 162 1/3 innings.

I wouldn't want to rely on Verlander in his age-42 season, but as a late-round pick, there's not much risk involved in taking him. I think he's a better deep-league option though, and might just be usable in standard leagues as a streamer.

Ray is in a similar boat to Verlander, but much younger (33).

In seven starts a season ago, Ray went 3-2 with a 4.70 ERA. He struck out 43 batters over 30 2/3 innings. Ray is a couple years removed from a full season of starts, but with 460 strikeouts between 2021-22, there's some fantasy intrigue with Ray yet.

Again, I have no issues with using one of your final standard league picks on Ray. He's likely not going to be a keeper all season though, but should be a pretty good option in deeper leagues, and be a standard league starting option every turn through the rotation.

Other Starting Options

According to FanGraphs, Jordan Hicks and Kyle Harrison are the two other projected members of the starting rotation.

Tyler Rogers and Camilo Doval are the projected setup men for Walker. Erik Miller, Sean Hjelle, Lou Trivino and Randy Rodriguez are the other projected bullpen arms, while Tristan Beck fills the long reliever role. Keaton Winn is another starting option, but is banged up to start the season. 

Hicks was primarily a starter in 2024, making 20 starts across 29 appearances. He went 4-7, but with a respectable 4.10 ERA. He struck out 96 batters over 109 2/3 innings.

Hicks is another late-round option in standard league drafts, but probably should only be rostered in deeper leagues to begin the season. He's worth keeping an eye on in case he gets hot and has a favorable matchup, but I don't think he'll be a standard league keeper.

Harrison didn't improve in his second MLB season like many expected.

In 24 starts, Harrison went 7-7 and had a 4.56 ERA. He struck out 118 batters over 124 1/3 innings.

I still am not giving up my high hopes for Harrison, but after last season, he'll begin the 2025 campaign as just a deep-league option. Harrison will be streamable at points this season as well, so keep him on that list of pitchers.

Winn could be a rotation replacement if anyone is struggling or injured, or maybe take the long reliever role away from Beck. In 12 starts in 2024, Winn went 3-8 with a 7.16 ERA. He struck out 48 batters over 55 1/3 innings.

I don't think Beck or Winn will be big fantasy assets in 2025, but if they make some starts, they could be usable as streaming options.

Doval is a name to keep an eye on. He was the team's closer over the past few seasons, but really struggled last year. Doval could become a nice fantasy asset even if he's a setup guy, or maybe could get moved to a team needing a closer, so don't forget about him.

Rogers doesn't strike out many batters, but a lower ERA helps him post pretty solid fantasy results.

I don't see any other San Fran relievers being big fantasy assets. It would take a few injuries for any of them to be the closer, and they'd need to rack up a ton of strikeouts or have a really low ERA to make a difference in their current roles.

Top Prospects

There's no San Francisco pitching prospects in the top-100 list put out by MLB.

Mason Black, Trevor McDonald, Carson Seymour, Carson Whisenhunt and Reggie Crawford are some of the team's top-30 prospects from the end of last season who could maybe factor into things in 2025.

Whisenhunt has a career 4.04 ERA across three minor league seasons. He has 238 strikeouts over 176 innings, but 80 walks and a .239 average against him.

Black went 1-5 across eight starts and nine games with the big league team in 2024. He had a 6.44 ERA and 31 punchouts over 36 1/3 innings. Black has a better 3.77 career ERA in the minors, along with 378 strikeouts over 320 innings, so I bet the team will give him another shot at some point. 

Crawford has been a two-way player in the minors, but has struggled with health. He has a career 2.89 ERA across two seasons, but that's in just 37 1/3 innings. Crawford has 62 strikeouts over 37 1/3 innings, so he looks more like a bullpen option than a rotation piece.

McDonald pitched three scoreless MLB innings in 2024. He has a 3.15 ERA across parts of five minor league seasons, and with 328 strikeouts over 309 innings, there's a little potential with him.

Seymour has a career 4.00 ERA across four minor league seasons. He's got 385 strikeouts over 362 1/3 innings, so there's a little upside in the Ks with him too.

Hayden Birdsong, Juan Mercedes, Helcris Olivarez and Antonio Jimenez are a few other pitchers age 25 or below who are in big league camp with the team this spring.
