Every stadium in baseball has its unique quirks and traits.Fenway Park has the Green Monster. Wrigley Field has ivy-covered outfield walls. Oracle Park has the deep right-center field gap.Tropicana Field has the catwalks. And while it doesn't Chris Owings Jersey happen often, batted balls have been known to hit the catwalks and fall to the field, always sparking the question ofwhether the ball that just hit the ground is a home run or simply a fly ball.There are several ground rules to know when teams play the Rays at Tropicana Field, and that will undoubtedly come up as we as the Rays continue their postseason run. To help clear things up, here's a breakdown of the rules in Tampa on those lofty batted balls.MORE: There are four rings of catwalks above the field of play: the A, B, C and D rings.First, there are the lower two catwalks. These are the C-Ring and D-Ring. Any fly ball that hits those two, or any lights,suspended objects or angled support rods from them in fair territory is considered a home run.MORE: Then, there are the upper catwalks: A-Ring and B-Ring. If a fly ball hits either of those rings in fair territory, it is fair game to be caught or land for a base hit. Though it might deflect off the rings, it can be recorded for an out, unlike batted balls that bounce off walls in other ball parks.Here's a look at where the rings are.Everything youve always wanted to know about Tropicana Field Jeff Eisenband (@JeffEisenband) There's still more to know about the catwalk rules. If a batted ball in fair territory is not judged to be a home run, but does not return to the field of play and is stuck on the catwalk, light or suspended object, it is considered a ground-rule double.However, if the ball hits anything in Salvador Perez Jersey foul territory, it is ruled a foul ball and a dead ball. The foul lines and center field distances are not particularly different at Tropicana Field than at any other ballpark.According to Baseball Pilgrimages, the outfield is 315 feet to left field, 404 feet to center field and 322 feet to right.But those catwalks add in an extra dimension for which to account. Below are the heights of the rings above the field.RingAbove CenterAbove Home PlateA181194B142173C99146D59121At just 59 feet above center and 121 feet above home, the D-ring is not far above the field of play. However, given how wide the ring goes around the field, it is unlikely to be struck unle s the ball is already headed out of the field of play. Tropicana Field is the only fixed stadium in the sport.But there are several other retractable-roof parks in the game that will occasionally have a cover over the field: American Family Field Kelvin Herrera Jersey in Milwaukee, Chase Field in Phoenix, Globe Life Field in Arlington, Texas, LoanDeport Park in Miami, Minute Maid Park in Houston, Rogers Centre in Toronto and T-Mobile Park in Seattle.None of the other parks sharesthe same potential catwalk concerns that Tropicana Field faces. For the stadiums with retractable roofs, the rules are simply that if a batted ball hits the roof over fair territory, it is in play and if caughtis an out. If it hits the roof in foul territory, it is a dead ball. There have been many players over the years in Tropicana Field who have hit the catwalks, some have gone for hits, some for outs, some for homers.The most recent example was , when he hit the C-ring catwalk. , it was expected to travel 406 feet after leaving his bat at 105 mph and traveling at a 39-degree launch angle.MORE: A list of every Cheslor Cuthbert Jersey batted ball to hit the catwalks would be far too long to include here. The list in the postseason is a bit easier. , five players have hit a fair ball on the catwalks in the playoffs. Evan Longoria was the first, launching a homer off the C-ringin Game 1 of the 2008 ALDS. B.J. Upton hit the C-ring in 2008 during Game 6 of the ALCS. Willy Adames hit one off the D-ring in Game 4 of the 2019 ALDS. Toronto catcher Danny Jansen became the only road player to homer off the catwalk when he hit the D-Ring in Game 2 of the 2020 AL Wild Card Series.Perhaps one of the biggest outliers in the stadium's history came in 2018, when Billy Hamilton Jersey Yankeesoutfielder Clint Frazier lifted a fly ball that hit off a B-ring speaker in the ninth inning on June 24. The ball was caught by shortstop Adeiny Hechavarria for an out. However, projected the distance to be 335 feet, which would have been a home run had it been hit straight down the left field line, which has a fence at 315 feet at the foul pole.
