Just three months before Joe Musgrove was slated to become a free agent for the first time, the San Diego Padres are close to signing the 29-year-old El Cajon-native to a five-year, $100-million extension.

The team made it official Monday after multiple insiders made the initial reports Friday.

Musgrove was acquired from the Pittsburgh Pirates in January of 2021 as part of a three-team trade that sent southpaw Joey Lucchesi to the New York Mets, and David Bednar and Omar Cruz to Pittsburgh.

Since then, Musgrove has been on another level for San Diego. He had the best season of his career in 2021, his first year with the Padres, that saw Musgrove throw the first no-hitter in Padres’ franchise history. He has been even better this year.

In 49 starts (and one relief appearance) with San Diego since the start of the 2021 season, Musgrove has a 2.97 ERA and 1.05 WHIP while striking 9.6 batters per nine. He also threw his first two career complete game shutouts – Apr. 9, 2021, at Texas and Aug. 27, 2021, at the Angels.

He started the 2022 season with 12 consecutive quality starts, posting a 1.59 ERA and 2.65 FIP in 79 innings pitched. Opponents hit just .196 while striking out 9.2 batters per nine during that stretch.

With the five-year extension, Musgrove will be a lock in the Padres’ rotation until 2027, his age-34 season.
