Applauding the Season That Was: Randy Rodriguez’s Breakout

In the early months of the 2025 season, the San Francisco Giants had the best bullpen in all of baseball. There was almost no pressure on the starters to go deep into games simply because once the game got turned over to the ‘pen, it was seemingly over.

During this run, the group was led by a three-headed monster of guys shining in the department of not allowing runs. As a matter of fact, these three arms had the three best individual ERAs of all relievers at one point.

On June 24, Randy Rodriguez had a 0.79 ERA, Erik Miller had a 1.03 ERA, and Tyler Rogers had a 1.24 ERA. Now, we are going to focus on the breakout star of these three who has made a name for himself this season, Randy Rodriguez.

Unfortunately, he is scheduled to have Tommy John surgery at the end of the month, ending what was an extraordinary season. Let’s take a look at the young reliever’s 2025 and how he got here.

Prior to the Breakout

Rodriguez was a fairly high ranked prospect when it comes to relievers. Seemingly, players at this position don’t get as much prospect love simply due to the fact that they won’t be on the field as much as others. However, Rodriguez managed to be the Giants number 13 ranked prospect in 2022 according to MLB.com.

He was performing like an elite bullpen prospect, as well. In 2023 at Double-A Richmond, Rodriguez had a 2.97 ERA in 16 games with an impressive 11.87 K/9. Just the next year, 2024, prior to getting called up to make his debut, he had an elite 1.69 ERA in 10 games at Triple-A Sacramento.

The fastball was the true calling card, but the slider was mediocre and he struggled to keep the ball in the strike zone consistently. Despite that, Rodriguez made his MLB debut in May of 2024.

Overall, it wasn’t the rookie season that fans expected from the overpowering reliever. He finished with a 4.30 ERA in 52.1 innings. Rodriguez also really struggled when it came to free passes, walking over three guys per nine innings.

Almost more alarmingly, the fastball was not performing as well as many would assume. While it still held a 110 Stuff+ rating, it held a -2.2 runs above average rating as well. While he showed some flashes of what could be, there weren’t a ton of expectations for Rodriguez heading into 2025.

The Breakout

In the early weeks of the season, it was safe to say Rodriguez was exceeding expectations as he looked absolutely unhittable. He didn’t allow an earned run until his 12th inning of the year and was striking out 12.3 hitters per nine up until then.

It didn’t end there, either. After giving up two earned runs in that 12th inning of the year, the breakout reliever went on an absurd run of dominance.

This run cemented Rodriguez as the best reliever in baseball up to this point and put his name on the map. He became the first Giants pitcher ever to strike out 20 batters and allow no earned runs in a calendar month, per Alex Pavlovic. Fans all over the country were learning of the Giants’ reliever and cases for his first All-Star appearance were being made left and right.

As a matter of fact, our own Jack McMullen was an early supporter of Rodriguez making the midsummer classic. He had this to say on an episode of the podcast on June 18th.

“If Randy Rodriguez is not an All-Star in the National League, we riot.”

It ended up coming to fruition as Rodriguez was one of the relievers sent to the game from the National League. The only reason it was surprising was due to the fact that he was not a closer, and All-Star relievers are typically closers.

Rodriguez went into the All-Star break with a miniscule 0.86 ERA, the best in baseball, with 55 strikeouts in 41.2 innings. The fastball jumped from that -2.2 runs above average in 2024 to a positive 7.3 in 2025. Adding to this, of all relievers who have thrown at least 50 innings this season, it is tied for the second best in terms of Stuff+ at 122.

This capped off one of the most impressive runs we’ve seen from a reliever in recent memory. Rodriguez cemented himself as one of the elite bullpen arms in baseball that every fan wish they had on their team. For a reliever who had struggled in his rookie season, he flipped the script in a single offseason.

Unfortunate News

Interestingly, after the All-Star break, Rodriguez looked like a completely different person. He had a 6.00 ERA and while he was still striking out the world, he was now walking three guys per nine innings again. Something was clearly off.

Initially, Rodriguez wasn’t throwing in situations he normally would which we found out was due to arm soreness. However, the news that quickly followed was the worst case scenario for the 26-year-old.

While he took a few days to officially decide, Rodriguez is now set to have the surgery later this month. What was looking like just the beginning of an elite reliever’s career, has now taken a turn.

Now, Giants fans won’t see the head of their bullpen until 2027 and it will force Buster Posey to rebuild the entire group heading into next season. While it’s easy to focus on the negatives of the situation, we can’t forget how good Rodriguez was in 2025’s entirety.

He finishes the year with a 1.78 ERA, 11.90 K/9, 1.4 fWAR, and 67 strikeouts in 50.2 innings thrown.

While it may be a while, the Giants now have a piece in their bullpen that looks like a real building block. Once he returns, Randy Rodriguez will slide right back into this bullpen in order to continue this level of dominance and, hopefully, be even better.
