Padres to name top prospect Jackson Merrill their Opening Day center fielder

The Padres are poised to name top prospect Jackson Merrill the club’s Opening Day starter in center field, per a report from MLB Network’s Jon Morosi. The news comes just days before the club is set to face the Dodgers in a two-game regular-season set in South Korea as part of MLB’s Seoul Series. Game 1 of that set is scheduled for 5:05 a.m. CT Wednesday morning or 7:05 p.m. local time that evening. The club will need to select Merrill’s contract before then, but won’t need to make a corresponding 40-man roster move as the roster currently stands at 36.

Merrill, 21 in April, was the club’s first-round pick in the 2021 draft and is a consensus top-20 prospect in the sport. The youngster is something of a surprising choice for the role, at least on paper. He’s not yet played a game above Double-A in his big league career, having slashed a solid but unspectacular .277/.326/.444 in 114 games split between the High-A and Double-A levels last year. Perhaps even more importantly, Merrill had never appeared in center field in a professional game until camp opened last month. His professional outfield experience to that point consisted of 45 innings of work in left field. Prior to that, his professional work had come almost exclusively at shortstop, though he also made brief cameos at both first and second base.

With all that being said, the club’s decision to go with Merrill in center field on Opening Day is certainly a defensible one. Prospect evaluators around the game are unanimous in their belief in Merrill’s talent, with Baseball America lauding him as a future middle-of-the-order threat who figures to have the power for 30 homers a year while FanGraphs describes him as having “one of the prettiest swings in the minors” with excellent contact abilities. Furthermore, while his lack of upper-level reps at the plate and professional time in center field will certainly raise some eyebrows, Merrill has clearly done everything he can to prove himself ready for a big league opportunity this spring. In 40 plate appearances across 13 games during camp, Merrill slashed an excellent .351/.400/.595 while playing solid defense in center.

Of course, the decision to roster Merrill as the club’s Opening Day center fielder is also the results of a host of other decisions outside of Merrill’s control. Chief among them is the club choosing to part ways with superstar Juan Soto alongside Trent Grisham in a trade with the Yankees that removed two of the club’s three Opening Day starters in the outfield last year from the roster back in December. Since then, the club has been tied to external outfield options including Michael A. Taylor, Kevin Kiermaier and Tommy Pham. The likes of Taylor and Kiermaier have since signed elsewhere, however. While there may be some momentum toward a deal with Pham, the 36-year-old veteran hasn’t appeared in center field on a regular basis since 2018, with just 15 starts up the middle in the years since then.

That lack of clear options for the center field job led the Padres to look toward their internal, non-roster pieces for their next center fielder. Fellow prospect Jakob Marsee as well as veterans such as Oscar Mercado and Tim Locastro all joined Merrill as potential solutions in center when camp began last month, though of that group only Mercado was able to keep up with Merrill’s blistering performance this spring and the club recently tipped their hand regarding their decision by including only Merrill, corner bats Jose Azocar and Jurickson Profar and right fielder Fernando Tatis Jr. as outfielders on their 31-man travel roster for the Seoul Series.

It’s possible Merrill won’t be the only rookie with minimal upper-minors experience on the club’s Opening Day lineup, as the club also included Graham Pauley on their travel roster for the coming series. The Athletic’s Dennis Lin indicated last week that Pauley was likely in position to fill in for veteran third baseman Manny Machado at the hot corner to open the season, as Machado will begin the season at DH while he recovers from elbow surgery, which he underwent back in October. Pauley, 23, was a 13th-round pick by the Padres in the 2022 draft and enjoyed a breakout season last year as he slashed a whopping .308/.393/.539 in 127 games split between the Single-A, High-A, and Double-A levels.
