The Padres signed Lucas Giolito on April 22 to a one-year contract worth $2.8 million guaranteed, bringing him into their rotation late after injuries had already thinned the staff. By the time he was required to be with the major league team on May 16, he had worked through a brief minor league ramp-up and was quickly pushed into a role San Diego needed to fill.
That is why Giolito is drawing attention now. He did not sign during the offseason or spring camp, then spent two games each with Single-A Lake Elsinore and Double-A San Antonio before logging 17 innings with a 4.76 ERA in the minors. His first start for the Padres came May 17 against Seattle, a date that arrived with little margin for adjustment.
The fit made some sense on paper. Giolito had gone 10-4 with a 3.41 ERA for Boston in the 2025 season, then bypassed his $19 million option for 2026 and entered free agency. He also had a long injury history behind him, missing all of 2024 after UCL repair and ending 2025 on the injured list with the Red Sox, so a short-term deal gave him a place to re-establish himself while giving San Diego an inexpensive arm at a time of need.
What has complicated the picture is how the stuff has looked since he arrived. Giolito’s fastball, slider and changeup are all down 3 mph, and his pitch mix has shifted from a fastball-and-slider-heavy approach to one built more around the fastball and changeup. His fastball has sat around 93 mph, down from the level that once let him attack hitters with sharper separation, while the curveball remains only a show-me pitch at 3 percent.
That matters because the Padres did not bring him in as a long-term project. They added him in late April after Joe Musgrove, Nick Pivetta, Germán Márquez and Matt Waldron had already landed on the injured list, and the contract essentially forced the club to move him into the majors by May 16. The answer that now counts is whether Giolito can recover enough velocity and consistency to give San Diego something more than an emergency stopgap.
