If nothing else, Jim Palmer's attempted comeback with the Orioles during Spring Training in 1991 gave us one of the all-time great newspaper ledes: "Jim Palmer can still pitch underwear but he can no longer pitch baseballs."
Roger Clemens when he retired and one year younger than Nolan Ryan was at the time of his retirement.
Palmer's fastball topped out at 75 MPH during his lone Spring Training game, some seven miles per hour faster than Ryan's first pitch in Arlington during the 2010 World Series. Palmer allowed two runs on five hits, a walk, and a balk in two winnings of work against the Red Sox with Boston batters missing contact only once in 15 swings.
Despite stating after his lone exhibition outing that it would be "premature to quit now," Palmer's comeback attempt indeed ended due to a hamstring injury he suffered while running wind sprints prior to facing the Red Sox. He likened the sound he heard to a Rice Krispie pop. In an earlier intrasquad game, Palmer tossed two innings and allowed two runs on four hits, one of which was a wind-assisted home run by catcher Chris Hoiles.
Sports Illustrated chronicled Palmer's efforts - along with those of other aging pitchers like Goose Gossage, Steve Howe, and fellow Orioles camper Mike Flanagan, age 39 - in the March 11, 1991, article "Hope Flings Eternal."
Here are a couple of excerpts from that piece:
Because Palmer remains a legend in Baltimore, the Orioles felt obliged to find out. They sent scouts to see him three times, including minor league pitching instructor Dick Bosman, who beat Palmer for the American League ERA title in 1969. Although none of the observers required surgery to have their eyes put back into their sockets, the Orioles invited Palmer to their camp in Sarasota. There he has failed to excite either ridicule or astonishment. He's in fabulous condition, no question. But no matter whom he lines up with on the row of practice mounds, there is more pop in the gloves of catchers other than his.
