Bob Welch's best year was with his second team, Oakland, but his longest tenure was further south, in Los Angeles, where he served his first ten years of MLB service.

Welch went to his only All-Star Game as a Dodger in 1980 and was an excellent near-the-top-of-the-rotation player for Los Angeles for the rest of his Dodgers tenure.  A First Round Pick in 1977 (20^th Overall), Welch debuted for L.A. the following year, helping the Dodgers win the pennant.  They lost in the World Series, but he put himself on the map with a two-out ninth-inning K on Reggie Jackson.

Welch helped L.A. win the 1981 World Series and, over the next four years, was decent, winning at least 13 Games in each year, including an eighth-place Cy Young finish in 1983 (15-12 2.65 ERA).  After a poor 1986, Welch's 1987 was deceptively good, with a 15-9 year and league-leading 7.1 bWAR for Pitchers.  

There was still life in his arm, but the Dodgers traded him to Oakland, where he won a second World Series and a Cy Young Award, though, to be fair, Los Angeles won the 1988 World Series without him. 

With the Dodgers, Welch compiled a 115-86 Record with a 3.14 ERA and 1,292 Strikeouts.

Bob Welch split his career between two California teams, the Los Angeles Dodgers and the Oakland Athletics, and he brought success to both of those squads.
