Joel Peguero

29-Year-Old PitcherRP
San Francisco Giants
2026 Fantasy Outlook
Peguero could emerge as one of the next-in-line candidates for saves in San Francisco after pitching reasonably well for the Giants during his first taste of the majors (22.1 innings) last season. The 28-year-old's minor-league track record doesn't jump off the page - through nine seasons he's posted just a 4.73 ERA and 1.50 WHIP - but the right-hander can hit triple-digits on the radar gun and produce plenty of groundballs with his sinker. While Peguero's strikeout and walk rates don't scream "future closer" in the league, bullpen roles in San Francisco appear to be wide open. A strong spring and continued success for Peguero could result in more opportunities in 2026, but improving his command will only increase his chances for a high-leverage role. Read Past Outlooks

Returns to Giants' bullpen
PSan Francisco Giants
May 5, 2026
The Giants reinstated (hamstring) from the injured list Tuesday, Justice delos Santos of The San Jose Mercury News reports.
Analysis
Peguero has been on the injured list since the beginning of the season due to a Grade 2 hamstring strain he suffered during spring training. He started up a rehab assignment at Triple-A Sacramento on April 7 and will now return to the Giants after posting a 4.82 ERA and 0.86 WHIP through 9.1 frames in the minors. The 29-year-old righty held his own in the big leagues last season, posting a 2.42 ERA and 1.03 WHIP over 22.1 innings, and he'll likely work in a setup or middle-relief role with San Francisco.
