Sometimes, offseason acquisitions work out. Sometimes they don't. Sometimes, they are spectacular failures.
The Red Sox suffered through some terrible production out of their catchers in 1993. Tony Pena was the starter, going .181/.246/.257/.502 in 347 at-bats. Bob Melvin went .222/.251/.313/.564 in 190 at bats and John Flaherty went .120/.214/.200/.414 in 29 at-bats. So the team decided to bring in a couple of better hitters in 1994, letting Pena and Melvin go and trading Flaherty. Dave Valle was a decent-fielding, good-hitting catcher who went .258/.354/.395/.748, with 13 home runs for Seattle in 1993.
He would not replicate that success for Boston. Valle ended up only playing 30 games for the Red Sox in 1994 and was terrible. His line for Boston was .158/.256/.250/.506 with only one home run and five RBIs. He lost his starting job to fellow new pickup Damon Berryhill due to his inability to hit and later lost the backup job to rookie Rich Rowland who was acquired for John Flaherty. Valle had a bad year behind the plate too, giving a total WAR of -0.4.
Valle was traded in June to the Brewers for Tom Brunansky and hit well for 16 games. At least Brunansky performed reasonably well in his return to the Red Sox. That is about the best thing to say about Dave Valle's Red Sox tenure.
