It appears as if organizational soldier / catcher Max St. Pierre will be called up by Detroit as soon as Wednesday, CKAC Sports of Montreal, Quebec, reports. This has not been confirmed by the Tigers, MLB.com's Jason Beck writes on Twitter.
(Update) John Wagner of the Toledo Blade now says it's official.
Earlier, Wagner wrote on Twitter that St. Pierre was pulled from the Mud Hens' game in the fourth inning and received a handshake from the opposing manager.
This is the 14th season in the minor leagues for 30-year-old St. Pierre, who has never has as much as a sip of coffee in the major leagues. He's spend almost all of it in the Tigers organization, though he was briefly under the control of the Milwaukee Brewers.
In 146 plate appearances with the Mud Hens this season, he has a .295 average, .352 on-base percentage and .465 slugging average. Combine that with a stay in Double-A Erie and he has a .270 average (.826 OPS) in 220 PA this season. (Baseball-Reference).
St. Pierre is not currently on the 40-man roster, but the Tigers do have room to add him.
I will update this story if it is officially confirmed, and you can certainly expect a full story Wednesday.
