Yesterday, the career Yankee Mariano Rivera announced that this 2013 season will be his last in the MLB. As arguably the best closer of all time, it is definitely heart-wrenching to see Rivera go, but he feels like he’s done “everything,” so there’s no point in trying to convince him to stay a little longer. As a lifelong Yankee fan, I have always considered Rivera a staple player on the field and it is sad to see another one of the Core Four hang up their pinstriped uniform. It puts things into perspective as to how long Jeter and Pettitte, who has already retired once before, will play in the game, just reminding me that there is definitely a new era in baseball. At least we have plenty of younger players, like CC Sabathia and Robinson Cano, who seem like they will do just fine making Yankees everywhere proud of their team. Rivera’s departure from the sport also marks the end of the number 42 jersey in the MLB. It was retired in 1997 in honor of Jackie Robinson, a baseball legend in his own right, and Rivera will be the last player to sport the number on his jersey. Personally, his record as a 5-time World Series champion, 12-time All-Star, and all-time leader in saves, proves that Rivera has worn his uniform well and has made all of his supporters proud. For now, we have to enjoy Rivera during his last season in the MLB and we can look forward to seeing him in the Baseball Hall of Fame. I’m just glad and grateful for the fact that I got the opportunity to see one of the greats play in person.
