Denehy was in Detroit by 1971, for whom he appeared in 31 games, going 0-3 with a 4.22 earned run average over 49 innings pitched.
As for those appearances it would be the most he had in any of his three seasons as a Major League pitcher, but he did pitch 53.2 innings in his rookie year of 1967 with the Mets, when he posted a 1-7 record.
The following year saw him pitch in only three games, this time for the Washington Senators, getting in only 2-innings.
He’d only see minor league action the following two seasons before making it back in ‘71, turning out to be the last big league appearances of his short career.
All told he finished with a record of 1-10 with a 4.56 ERA over 49 games, nine of which were starts, and 104.2 innings pitched.
But at least he can tell people his rookie card is worth a LOT of money!
