As one of the oldest franchises in baseball history, picking the top five Giants pitchers of all time is a tough task. The top of the list is clear, but so many great arms have played in San Francisco and New York as to make the rest of the top five a crapshoot.
Plus, given the age of the franchise and how dominant they were in the dead-ball era, even, distinguishing between that epoch of pitchers and the more modern ones makes things even tougher.
But, it’s our list and we tried. Some iconic names are left off the list, including 21st-century Giants postseason hero Madison Bumgarner. Here’s who made it.
The age-old question: Is it better to burn out or fade away? Those who believe in the latter might immediately kick Lincecum to the curb. Maybe not even put the lithe right-hander in the top 10. Fair enough. But for a brief bout, as the 2000s turned into the 2010s, he may have been the best pitcher in baseball.
Lincecum played nine years with the Giants, debuting in 2007 as he cracked the rotation upon call-up in early summer. The very next year, he was the National League Cy Young Award winner, leading all of Major League Baseball in strikeouts, WAR, and home runs per nine.
In 2009, he won the award again with eerily similar numbers. He helped the Giants to a World Series win in 2010 by picking up 16 mound victories and made his fourth and final All-Star Game in 2011.
Lincecum’s career hit the skids after that as he registered a negative-3.4 WAR combined over his final three seasons in San Francisco. But if you prefer Bumgarner’s longevity over Lincecum’s prime here, we totally understand.
It would have been easier to place one of the two Giants 2010s stars here instead of Rusie. Unless you’re a Giants historian, you’re probably - ahem - unfamiliar with his game.
Rusie pitched his entire New York Giants career (eight seasons) before the turn of the century. The turn of the 20th century, that is. From 1890 to 1898, Rusie racked up a 234-163 record with a 2.89 earned-run average. He led all of baseball in strikeouts five times…and walks five times. It was a different, wild era. He was great enough, anyway, to make this list.
The first great pitcher in the organization's history in San Francisco, Marichal was a 10-time All-Star who finished with MVP votes seven times in his 14 years with the franchise.
Marichal hit the scene in the Bay Area in 1960 alongside fellow future superstars Orlando Cepeda and Willie McCovey, providing the Giants the basis for one of the best National League teams of the 1960s. In 1962, when the Giants fell in seven games in the World Series, Marichal picked up the first of eight straight All-Star appearances.
He would go on to lead the NL in WHIP twice in the decade, walk ratio three times, wins and innings twice, and WAR once. Marichal was voted into the Hall of Fame in 1983, just eight years after he retired.

In the era of the Great Depression up to the start of World War II, few were better on the mound than Hubbell. A Missouri native who grew up in Oklahoma, the two-time NL MVP made a home in New York with the Giants.
Hubbell led the NL in WHIP an astounding six times and ERA and wins three times each, too, from 1931 to 1938. He debuted with the Giants in 1928 and played through his age 40 season in 1943, leading the team to a World Series win in 1933 and two more appearances in 1936 and 1937.
Hubbell’s wins, WAR, and innings pitched totals rank him second in team history, all behind just one man.
Mathewson is, by far, the greatest pitcher to wear a Giants uniform. That’s no knock on the others, but a testament to his dominance as one the greatest pitchers in baseball history. Just consider his statistics:
He never won an MVP award and the Cy Young Award didn’t exist yet, but Mathewson’s 373 wins rank fourth in MLB history, while his all-time WAR mark of 100.6 ranks sixth.
