Entering Sunday, Doumit had caught 10 of Diamond's starts with Diamond posting a 4.82 ERA, while Mauer caught just five of Diamond's starts with a 5.93 ERA. But over Diamond's career, both catchers' numbers are similar, with a 4.31 ERA in 18 starts with Doumit catching and a 4.33 ERA in 22 outings with Mauer.
"I've got all the paperwork detailing all that, and I think either one of my catchers works well with him," Gardenhire said. "I don't want to say it's a perfect match, but it's worked out a couple times, so we'll see. More than anything, Morneau was going to DH today, so I put Joe at first to keep him from bending and squatting. We also like Doumit behind the plate with his bat. And the matchup goes into play, too."
