Poll: The Cardinals’ Center Field Battle

As the Cardinals look to embrace a youth movement in John Mozeliak’s final year at the helm of the club, their inability to trade Nolan Arenado this winter has caused some complications. With Arenado ticketed for everyday playing time at third base, St. Louis now has five players for three spots in the lineup: second base, left field, and center field. While none of those five players can play all three of those positions, the versatility of Brendan Donovan to play either second base or left field connects the decisions made in the outfield to those at the keystone.

Donovan and Lars Nootbaar are both more or less guaranteed everyday playing time with the Cardinals, and one of them figures to be the club’s starting left fielder. Should Donovan start in left field, it would push Nootbaar to center, and that would open up second base for Nolan Gorman, who would have taken over for Arenado if the veteran were traded. Meanwhile, starting Nootbaar in left would push Donovan back onto the infield, and in doing so would open up center field for one of Michael Siani or Victor Scott II.

Scott and Siani are very similar players. Siani is a little over a year older than Scott, headed into his age-25 season while Scott has only just turned 24, and the pair combined for nearly 85% of the club’s innings in center field last year. Both are left-handed hitters who have struggled to hit in the majors so far, but are very well-regarded for their speed and defense nonetheless.

Of the two, Siani has the edge in terms of big league experience. After brief stints in the majors with the Reds and Cardinals in 2022 and ’23, Siani enjoyed his first extended taste of big league action last year when he appeared in 124 games for St. Louis and stepped up to the plate 334 times. He hit a paltry .228/.285/.285 in that time, good for a 64 wRC+ that was 36% worse than the league average hitter and the eighth-lowest slash line among hitters with at least 300 plate appearances. With that being said, Siani went an excellent 20-for-23 on the basepaths while posting +16 Outs Above Average, a 99th percentile figure that placed him behind only Nationals defensive standout Jacob Young among outfielders.

Unfortunately, there’s little in Siani’s profile that suggests a significantly higher offensive ceiling than he demonstrated in 2024. His actual batting average and slugging percentage both outstripped his expected numbers in those categories by more than 20 points last year, and…
