Davis won three Gold Gloves, and probably should have had more. Baseball-Reference has him as compiling 10.9 WAR of his 54.5 career WAR from his defense alone. FanGraphs rates his defense higher than his offensive WAR contributions, due to using TotalZone marks that rate him extremely high. There were no UZR stats in those days (obviously) and Fielding Bible doesn't go back that far. But it's pretty well established that Davis was one of the best defensive center fielders in Dodgers history.
Davis played for the LA Dodgers from 1960-1973. He had one more good season for the Montreal Expos in 1974, before just sort of hanging on with the Texas Rangers and St. Louis Cardinals the next season. He got into 141 games with the Padres in 1976, bounced around the minors for awhile and got into 43 games for the California Angels in 1979 for his last major league action.
I wouldn't say that Davis was a Hall of Fame player, but he was extremely good. He definitely should have won more Gold Gloves than he did. Sadly, Willie is no longer with us as he passed away at age 69 in March of 2010. You will be missed, Willie. Thanks for the memories.
Do Willie Davis Baseball Cards Have Value?
Because Willie Davis played in the 1960's and 1970's, his cards are fairly valuable, especially in near-mint to mint condition. In fact, there are only 721 PSA 9 examples of his 1961 Topps rookie card, plus 7 more with Off-Center qualifies (which essentially drops it to roughly a PSA 7 value-wise). Because of its rarity, a PSA 9 example sold just before Christmas 2018 for $350! PSA 8 examples are much more affordable in the $45-50 range, although you can find them for less. Still, there are only 177 PSA 8 examples as of February 2019. Despite PSA 7 examples being even rarer than PSA 8, they can be found for under $20.
But his 1961 Topps Rookie Card isn't Willie Davis's most valuable baseball card by far. One of his most expensive cards ever sold at auction was a 1970 Topps PSA 10, of which there are only 4 (as of this writing). It sold on ebay for $750 in January 2019. A PSA 8 copy the Willie Davis card of the rare 1968 Topps 3D set sold for $488 in December 2018. There are plenty of other high-graded Willie Davis cards worth money, too. Playing for the Dodgers for such a long time definitely helps his cards' collectible value.
