Question: What great lake is the Rogers Centre situated on, originally named SkyDome, where the Toronto Blue Jays of the American League East division of Major League Baseball play?
Context: The 2018 Toronto Blue Jays season will be the 42nd season of the franchise in the American League East division of Major League Baseball (MLB), and the 28th full season of play (29th overall) at Rogers Centre. The 2011 Toronto Blue Jays season was the 35th season of Major League Baseball's Toronto Blue Jays franchise, and the 22nd full season of play (23rd overall) at the Rogers Centre.  It was also the first season with John Farrell as the team's manager.  The Blue Jays had an up-and-down season, finishing with an 81–81 record, in fourth place in the American League East. The Toronto Blue Jays are a Major League Baseball (MLB) franchise based in Toronto, Ontario, Canada.  They play in the American League East division.  Since the Blue Jays' entrance into the league in 1977, the Blue Jays have selected 70 players in the first round.  Officially known as the "First-Year Player Draft", the Rule 4 draft is MLB's primary mechanism for assigning amateur players from high schools, colleges, and other amateur clubs to its teams.  The draft order is determined based on the previous season's standings, with the team possessing the worst record receiving the first pick.  In addition, teams which lost free agents in the previous off-season may be awarded compensatory or supplementary picks.  The First-Year Player Draft is unrelated to the 1976 expansion draft in which the Blue Jays initially filled their roster. The 2017 Toronto Blue Jays season was the 41st season of the franchise in the American League East division of Major League Baseball, and the 27th full season of play (28th overall) at Rogers Centre.  For the first time since the 2014 season, the Blue Jays failed to make it to the postseason, finishing fourth in the AL East with a 76–86 record. The 1991 Major League Baseball All-Star Game was the 62nd playing of the midsummer classic between the all-stars of the American League (AL) and National League (NL), the two leagues comprising Major League Baseball.  The game was held on July 9, 1991, at SkyDome in Toronto, the home of the Toronto Blue Jays of the American League.  It was only the second time that the game was played outside the United States, as the National League's Montreal Expos hosted the 1982 Midsummer Classic at Olympic Stadium in Montreal, Quebec.  The game resulted in the American League defeating the National League 4-2.  Both the winning and losing pitchers represented the Canadian teams; the Blue Jays' Jimmy Key earned the win while the Expos' Dennis Martínez was given the loss.  This was also the only All-Star Game to be awarded by Commissioner A. Bartlett Giamatti, who awarded the game to the Blue Jays on Canada Day 1989. The Toronto Blue Jays are a professional baseball team based in Toronto, Ontario, and a member of Major League Baseball's (MLB) American League East Division.  Since June 5, 1989, the Blue Jays have played in the Rogers Centre (called the "SkyDome" until February 2, 2005).  Before that, they played at Exhibition Stadium.  The name "Blue Jays" was chosen via a contest in 1976 from among more than 4,000 suggestions. The 2015 Toronto Blue Jays season was the 39th season for the franchise, and the 26th full season of play (27th overall) at Rogers Centre.  The Blue Jays clinched a playoff berth on September 25, their first since 1993, ending what was the longest playoff drought in North American professional sports at the time.  On September 30, the team clinched the American League East Division and opened the playoffs by defeating the Texas Rangers in five games, in the American League Division Series.  The Blue Jays were eliminated in a playoff series for the first time since 1991, losing to the Kansas City Royals in six games, in the American League Championship Series. The 2012 Toronto Blue Jays season was the 36th season of Major League Baseball's Toronto Blue Jays franchise, and the 23rd full season of play (24th overall) at the Rogers Centre.  Their opening game was played on April 5 against the Cleveland Indians in Cleveland.  The Blue Jays finished 73–89, in fourth place in the American League East. The 1997 Toronto Blue Jays season was the franchise's 21st season of Major League Baseball.  It resulted in the Blue Jays finishing fifth in the American League East with a record of 76 wins and 86 losses.  With a massive re-design of their logos and uniforms, the Blue Jays attempted to re-establish themselves in the American League East by signing Roger Clemens via Free Agency and bringing All-Stars Carlos García and Orlando Merced through trade.  Although Clemens rejuvenated himself with the Blue Jays (en route to one of the best-ever single seasons by a starting pitcher, winning the Cy Young Award and the pitchers' triple crown), both Garcia and Merced ended up being flops as dismal overall hitting and an inconsistent bullpen doomed the Blue Jays once again to a last-place finish.  1997 also marked the end of the road for manager Cito Gaston, being fired near the end of the season (Gaston would eventually return to the team in 2008).  Longtime fan-favourite Joe Carter also played in his final season for the Blue Jays, as he was released at the end of the season. Rogers Centre, originally named SkyDome, is a multi-purpose stadium in Downtown Toronto, Ontario, Canada, situated just southwest of the CN Tower near the northern shore of Lake Ontario.  Opened in 1989 on the former Railway Lands, it is home to the Toronto Blue Jays of Major League Baseball (MLB).  Previously, the stadium served as home to the Toronto Argonauts of the Canadian Football League (CFL) and the Toronto Raptors of the National Basketball Association (NBA).  The Buffalo Bills of the National Football League (NFL) played an annual game at the stadium as part of the Bills Toronto Series from 2008 to 2013.  While it is primarily a sports venue, it also hosts other large-scale events such as conventions, trade fairs, concerts, travelling carnivals, and monster truck shows.
