The calendar has turned to February, which means the light is starting to appear at the end of the tunnels for winter sports since the postseason for those sports aren't too far off after a long regular season. Saturday is probably the first sign of that since it's going to be a big day for various sports. Here are the big events that are happening. - The Oakland County boys swim meet is going to be taking place at Lake Orion High School and as traditionally the case, it'll likely be the Birmingham Invitational with Brother Rice and Seaholm the favorites. - League wresting tournaments. With districts ready to start on Wednesday, just about every league will have their year-end tournamens on Saturday. The one Kosmo is most excited about is the OAA Red/White tournament at Oxford, which will feature county powers Oxford, Rochester and Clarkston. - Area hockey teams will also have a big Saturday with the annual OAA/MAC showcase taking place at the Onyx in Rochester. Kosmo wishes more sports would have such invites pitting the best in Oakland and Macomb Counties and it should be a fun day. It doesn't get better than all this activity on Saturday, and it should excite people waiting for the postseason for winter sports to arrive.
