The St. Louis Cardinals’ starting rotation has been a key topic throughout spring training, with discussions ranging from trade possibilities to finalizing roster spots. Derrick Goold recently provided an intriguing update on the potential structure of the rotation heading into the season.

The Cardinals are considering implementing a six-man rotation.

One of the most competitive roster battles has revolved around the back end of the rotation. With a week of exhibition games remaining, the decision remains unsettled. Goold’s latest report suggests that, in a surprising shift, the team may be open to starting the season with six starters, largely due to rookie Michael McGreevy’s impressive spring performance.

The Cardinals held a discussion this morning about the feasibility of opening the season with a six-man rotation.

McGreevy’s strong spring showing has been a key factor in that consideration.

Earlier in the offseason, the first four spots in the rotation appeared secure with Sonny Gray, Erick Fedde, Miles Mikolas, and Andre Pallante. This left the fifth spot to be contested between veteran Steven Matz and McGreevy. However, recent reports from Jupiter have suggested that Pallante, Matz, McGreevy, and Matthew Liberatore were all competing for spots. Liberatore has since been confirmed for a bullpen role, while Pallante is now seen as a roster lock.

At the start of camp, Matz seemed to have the edge for the final rotation spot as the team aimed to maximize the value of his contract. He has responded well, leading the team with 13.2 innings pitched, posting a 2.63 ERA, and recording nine strikeouts. However, he has also allowed nine hits and five walks. If Matz stays healthy, keeping him in the rotation could be in both his and the team’s best interest until a trade, release, or injury alters the situation.

McGreevy, however, has made a strong case for himself. After a promising debut last season, he entered camp determined to prove he belongs in the majors for a full season. His impressive performance has been a driving force behind the six-man rotation discussion. In 11.2 innings, he has yet to issue a walk, has struck out eight batters, and holds a 1.54 ERA. If the team believes he has earned a major league role, it would be more beneficial to keep him as a starter rather than shifting him to the bullpen.

With ongoing debates about young pitchers being blocked by veterans, the Cardinals appear to be considering their options carefully. A six-man rotation could provide extra rest for older arms, but it might also disrupt their routines. Manager Oli Marmol expects to make a final decision regarding the rotation soon.
