After signing Adrian Houser and Tyler Mahle to short-term contracts this offseason, it seems as if the San Francisco Giants have completed their starting rotation. However, it is worth wondering what adding free agent lefty Ranger Suárez could provide.  

Recently, The Athletic’s Grant Brisbee explored the possibility of signing Suárez. 

“Ranger Suárez shouldn’t still be a free agent,” he wrote. “There are 150 openings for a starting pitcher around baseball, in theory, and Suárez is one of the top 25 in baseball.” 

“We’ve established that he’s a good pitcher. The Giants would like as many of those suckers as they can get. They don’t want to give any of them a nine-figure contract, necessarily, but they’d love to build a collection.” 

Suárez is coming off a very strong 2025 campaign in which he punched a 12-8 record, a 3.20 ERA, 151 strikeouts and only 38 walks through 157.1 innings of work. Moreover, his advanced metrics further illustrated how good the 30-year-old southpaw is. 

“He can still get strikeouts, but he’s barely cracking 90 mph these days, in the bottom-10th percentile of all major-league pitchers for velocity,” Brisbee wrote. “He wouldn’t have been the softest tosser in the days of Tom Glavine, but he wouldn’t exactly have been a candidate to close, either. Suárez’s a classic lefty in the best sense. 

“Click through that link in the last paragraph, though, and take a gander at all the red ink on his Baseball Savant page. There is just so much of it, and there always is. Suárez is one of the best at allowing weak contact, with hitters having some of the worst exit velocities in baseball against him, season after season. And while he hasn’t gotten better at missing bats, he has gotten better at getting batters to chase, which leads to even weaker contact.” 

It is also worth noting that while the Giants have already added two starters this offseason in House and Mahle, the front office may not be done adding pieces, leaving the door open for a Suárez acquisition. 

“I don’t know if we’re ever done,” general manager Zack Minasian told MLB.com’s Maria Guardado. "I think we're very comfortable with the five that we have and then the bundle of arms behind them now. Our depth is in a much better spot than it was at the beginning of the offseason.”  

“We’ll keep working at it, but we do think this is a solid five-man rotation going into the spring."
