Coors Field conundrum: Jake McCarthy's speed makes lineup choices a tough call

The Colorado Rockies acquired Jake McCarthy for his speed, defensive versatility across all three outfield positions, and base-stealing prowess.

McCarthy endured a disappointing season in 2025, posting just a .204 batting average, 20 RBI, and a meager .592 OPS across 206 at-bats with the D-Backs.

He went 0-for-30 at one point, which eventually led to his demotion to Triple-A. There, he turned things around and hit .314.

McCarthy was featured in the top ten of MLB players with the fastest sprint speed, posting 29.9 ft/sec—not far behind Trea Turner and Bobby Witt at 30.3.

That kind of speed is perfect for Coors Field's spacious outfield.

It'll be interesting to see what lineup combinations Warren Schaeffer has up his sleeve, whether he's facing right-handed or left-handed pitching.

Colorado started McCarthy in center field for its Cactus League opener Friday afternoon, with everyday left fielder Jordan Beck getting the start in right.

With Brenton Doyle occupying center field, Colorado's likely testing whether Beck can handle right field while giving McCarthy more space to cover in left.

We might be reading too much into that, but it's worth considering as we move forward.

Landing McCarthy also gives Colorado another left-handed bat, but more importantly, it gives them a lethal threat on the base paths.

During his 2023 campaign, McCarthy swiped 26 bags in 30 attempts—an 86.7% success rate.

He stole second base in the fourth inning of Friday afternoon's loss to Arizona, then scored on Cole Carrigg's RBI triple.

McCarthy is an interesting addition who can either serve as a platoon outfielder to spell Doyle on his off days, or if he hits consistently, he could find himself starting at either corner outfield spot.

Colorado only has three outfield spots, and McCarthy is competing with players like Mickey Moniak, who's coming off a career year, and veteran free agent signing Willi Castro, who can play multiple positions.

Colorado also has outfield prospects waiting in the wings: Cole Carrigg, Zac Veen, Sterlin Thompson, and even Charlie Condon—who's getting an extended look at first base but can play the outfield too.

You have to wonder if Moniak will primarily serve as the designated hitter this year—mainly against right-handed pitchers when Hunter Goodman is catching—or if the team will trade an outfielder at some point given their surplus depth.

McCarthy's closing speed in the outfield and ability to steal bases make him a tough player to keep out of the lineup for a Colorado team looking for answers.
