Kyle Gibson has made than any other active pitcher. This is his tenth big league season. He has made 259 starts. His only playoff appearance was one inning of relief back in the 2019 ALDS.Not so long ago, it was almost a given that Gibson would make a start were the to make the playoffs. But a lot can change over the course of a season.First Ranger Surez proved himself to be a true number three starter. After Aaron Nola and Zack Wheeler, he will be next in line to get the ball.Then Noah Syndergaard arrived. Almost as soon as Greg Monroe Jersey Thor came to town, for the no. 4 starter role.More recently, Bailey Falter has been pitching too well to ignore. He joined the rotation to replace the injured Wheeler, but he stuck around after Wheeler returned, forcing Syndergaard into a piggyback role. Before a disastrous appearance Rashad Vaughn Jersey on Saturday afternoon, Falter was having a terrific September and it looked like he might sneak past Gibson on the depth chart.Gibson, meanwhile, has had anything but a terrific September. He has given up 19 earned runs in 17.1 IP for a 9.68 ERA. He has made it past the fifth inning just once. In two of his four starts, he allowed seven runs to cro s the plate.Scroll to ContinueSo now, with le s than two weeks remaining before the MLB postseason kicks off, Philadelphias playoff rotation is still up in the air. Gibson remains in the mix to make his first career playoff start, but its far from a guarantee.Nola, Wheeler, and Surez are the one-two-three, but the fourth starter role is still very much up for grabs. It seemed like Gibson had the inside track, especially when Syndergaard was moved into a piggyback role, but Gibson has been floundering, and Syndergaard thrived in his first piggyback appearance with Wheeler. Then there is Falter, who got hit around on Ray Allen Jersey Saturday but has otherwise been better than either of them this month.To make matters more confusing, of Philadelphias top three starters, only Wheeler is on track to start in the Wild Card series. Nola and Surez are both in line to start during the final series of the season, and if the Phillies have yet to clinch their spot by then, they wont be able to rest two of their best starting pitchers. Rob Thomson will need to decide who is starting Wild Card Giannis Antetokounmpo Jersey Game Two on October 8, and it wont be Nola or Surez. (Update: to line up Nola to start in the second game of the Wild Card round.)It could Syndergaard. It could be Falter. But the most likely option is still Kyle Gibson. Its his job to lose and he just has to not lose it.Thus, the final starts of the season will play a crucial role in determining his fate and the fate of Philadelphias playoff rotation. If Gibson can find his footing and prove that his last few bad starts are behind him, there is a very good chance hell be making his first ever postseason starts this October. But if he cannot prove himself over the final days of John Henson Jersey the 2022 season, he could lose out on the opportunity hes been waiting for his entire career.More From SI's Inside The Phillies:
