Brock Davis was certainly never a star at the MLB level. In fact, he’d only get into 242 games over parts of 6 seasons, amassing a whopping 0.2 WAR over that time. He carried a decent .331 OBP in his career, but had only one home run and not much else.
Jim Gosger never had much of an MLB career, although he hung around for parts of ten seasons. His 1963 debut with the Red Sox was a dreadful 19 plate appearance cup of coffee. Gosger actually wouldn’t resurface in the Majors until 1965, when he wasn’t a star but instead a league average hitter who gave the Red Sox 1.4 WAR in only 81 games. He would be perfectly acceptable in 1966 as well, but he’d be traded midseason to the Kansas City A’s with a couple other players for three players, including Jose Tartabull, who would be awful for the ‘66 and ‘67 Red Sox. (Tartabull’s son Danny would be a decent player, though). Gosger would carve out a basically replacement level career as a reserve outfielder. He was definitely NOT a star, with a career total of 2.3 WAR!
Meanwhile, this Willie Stargell fellow would amass 57.5 WAR over 21 seasons all for Pittsburgh. He’d hit .282/.360/.529 for an .889 career OPS (147 OPS+). He also hit 475 home runs. While he was a below average defensive outfielder and first baseman according to TotalZone, Stargell was easily a Hall of Fame player.
Considering the other three guys COMBINED for 0.5 WAR, I think it’s safe to say this is a Willie Stargell rookie card with three random guys. (Although, one is a Red Sox player so it counts for my Red Sox collection, which is funny to say!)
