Among those adorable Chowds, Rico is a folk hero. He was made for Fenway Park. I heard an interview last fall on XM’s Baseball Channel (before Sirius took over and ruined it) of he and Jim Lonborg talking about the Impossible Dream Red Sox team from 1967. He talked about how he tailored his swing for the Green Monster and the thrill of having the soft liner that was the last out in the pennant clincher land in his glove. He's written a book about that team called "Tales From the Impossible Dream."
He was a big part of their team, hitting 40 homers as a shortstop in 1969 while making only 14 errors. He started having injury problems in 1974 and was never the same after being hit in the head in 1975, although he fared well in the Series against the Reds.
Looks like a Spring Training pose on this card. George Toma sure wasn’t the groundskeeper here. That patch on the right side of the card looks about like some of the softball fields I’ve played on. I can’t figure out who that is in the background. I’m going to say it’s some pitcher, although there’s really no telling.
