The Cubs will be without one of their top starters for at least the first round of the playoffs, as has been placed on the 15-day injured list (retroactive to September 25) due to a non-displaced right rib fracture. Left-hander was called up to take Hortons roster spot for the final two games of Chicagos regular season. Horton made an early exit from his last start on Tuesday due to back sorene s, and a follow-up MRI revealed an unspecified i sue in his ribcage, as manager told reporters earlier this week. Horton threw in the outfield yesterday and was slated to throw a bullpen se sion today, yet those positive signs have now been abruptly overshadowed by the news of the IL placement. In the best-case scenario, Horton is now out of action Wilt Chamberlain Jersey until at least Game 5 of the NLDS, should the Cubs make it that deep into the second playoff round. Given that narrow window for activation, it doesnt seem likely that the Cubs would include him on an NLDS roster, so a more realistic scenario would see Horton return as part of the NLCS roster if he can get healthy. Of course, Chicagos chances at such a deep postseason run will be a lot more difficult without the rookie who has emerged as a key rotation piece. Horton figures to get plenty of NL Rookie of the Year votes in the wake of a debut season that has seen the right-hander post a 2.67 ERA over his first 118 innings in the bigs. A 4.26 SIERA reflects Hortons underwhelming 20.4% strikeout rate and the good fortune he has enjoyed in the both of both a 78.3% strand rate and a .258 BABIP, but Hortons 6.9% walk rate is very solid. Theres also the fact that Horton (the seventh overall pick of the 2022 draft) was getting better as he gained more experience. He posted a 4.45 ERA acro s his first 56 2/3 innings, but then delivered just a 1.03 ERA over his next 12 starts and 61 1/3 frames. This was seemingly a good omen for Horton and the Cubs as the playoffs loomed, as the rookie had locked up a spot in Chicagos postseason rotation. The Cubs should have enough starting pitching options to get by, even if their depth chart has now been shortened. , , and either or will be the starters for the best-of-three Wild Card Series, and that quartet should line up as the rotation for the remainder of the postseason. is also in line to be at least a multi-inning reliever in October, and Counsell that hell use his entire pitching staff to navigate the playoffs, perhaps outside of traditional starter/reliever roles. With two games left in the regular season, the Cubs are two games ahead of the Padres for the top NL wild card slot. Unle s the Cubs go 0-2 and the Padres go 2-0 the rest of the way, their NLWCS will be played in Chicago, with Game 1 set for Tuesday. Dwight Howard Jersey
