It could be said that there are two unofficial Opening Days for Toronto Blue Jays games. Sportsnet's Joe Siddall was among those who spotted the Rogers Centre roof being toyed with on Monday by stadium staff, testing that it was still opening and closing as expected. With an average time of about 20 minutes to fully close or open, the Blue Jays can only test the Rogers Centre roof in warmer weather, as colder climates can damage both the roof and the stadium interior. The Blue Jays are at home this week for two different three-game series against American League opponents, kicking off on Tuesday. Given that a bit of rain is forecast for Toronto throughout Tuesday, the Blue Jays have not yet made a public announcement regarding whether they will open for the first time this season.
