Jung Hoo Lee's ceiling might not be as high as SF Giants would have hoped

The SF Giants' problems extend well beyond one player. That said, they were hoping for more from Jung Hoo Lee, who has been more fine than good. What takeaway is there from this season?

Overall, the numbers are solid. The left-handed bat is slashing .285/.329/.415 (107 wRC+) with nine home runs, 50 RBI, and 62 runs in 517 plate appearances. This includes a 5.0 percent walk rate, 9.7 percent strikeout rate, and .129 ISO.

The Giants hoped that Lee would bring some speed to the table. To some degree, he has. He has 12 steals in 13 chances this year. While he has been remarkably efficient, he can afford to be a little more aggressive as well.

Lee has been worth 1.3 fWAR, ranking 108th among 141 qualified position players. That is not the type of value the Giants hoped to realize when they signed him to a six-year, $113 million pact.

SF Giants outfielder Jung Hoo Lee has not demonstrated a high or even moderate ceiling

The defense is certainly weighing down his value. While the eye test might suggest otherwise, he continues to grade out as a below-average defender. It bears mentioning that playing half of his games at Oracle Park is likely hampering his defensive metrics.

That said, the Giants need to see more consistency from Lee in the batter's box. It has been a tale of three seasons for Lee, who has had two prolonged slumps sandwiched between an 18-game hitting streak.

Before that hitting streak began in May, Lee had a .685 OPS across 175 plate appearances. He posted a 1.159 OPS in 75 plate appearances during that 18-game hitting streak. That streak was snapped in the middle of June, and Lee's bat went cold. Since then, he has put up a .662 OPS in 267 plate appearances.

The 28-year-old outfielder had a prolonged slump in 2025 as well, where he struggled to a .586 OPS in 216 plate appearances from May 1 through June 30.

Giants fans are still learning about Lee. They know he has elite contact skills and can make things happen with the bat. He will hit for a good average and has continued to do so in 2026, but his profile comes with some wrinkles as well. He does not hit for much power, nor does he take a lot of walks. The batting average is doing a lot of the heavy lifting, and arguably too much of the lifting.

Then, there are the continued struggles against left-handed pitching. He has a .656 OPS in 159 plate appearances in those matchups this year, which is a step above his career .630 mark, but not enough to add leverage. Lee's numbers would likely benefit from a platoon partner, but the Giants have been relatively against that strategy in recent years.

What is there to take away from Lee's season? There will be a stretch of games where he is one of the best hitters in baseball. Then, he will go through a prolonged slump without offering much offensive value whatsoever.

The Giants did not seem motivated to move the outfielder at the deadline, but maybe that is a subject they broach again in the offseason. Undoubtedly, Lee is capable of being an everyday player, but the ceiling might be lower than they hoped.
