PHOENIX — A lineup that already features Fernando Tatis Jr., Manny Machado, Xander Bogaerts and Jake Cronenworth may be getting even better.

On Friday, a source told MLB.com’s Mark Feinsand that the Padres are finalizing a deal with the Marlins for two-time batting champion Luis Arraez. According to MLB.com’s Jon Paul Morosi, Miami will acquire right-handed reliever Woo-Suk Go and three prospects: outfielders Dillon Head and Jakob Marsee and first baseman/outfielder Nathan Martorella. The clubs have not confirmed the trade, which ESPN’s Jeff Passan first reported.

“It’s really amazing, the guy is a baller,” Tatis said following the Padres’ 7-1 win over the D-backs at Chase Field on Friday night. “The guy is probably the closest to Tony Gwynn that there is right now, so I’m looking forward to seeing him in the lineup.

“Only seven batting titles away [from passing Tony Gwynn],” Tatis said with a laugh. “That why I said the closest.”

High praise, but not without merit.

The 27-year-old Arraez led the AL with a .316 average in 2022, then led the Majors with a .354 mark last season to become the second player to win a batting title in consecutive seasons for different teams, according to the Elias Sports Bureau. Nobody has done it for three teams in three seasons. Arraez is currently batting .299 with the Marlins.

He also became the second player in the Modern Era to win a batting title in both the AL and NL and the first to do it in back-to-back seasons.

Arraez was traded from the Twins to the Marlins in January 2023 for Pablo López and a pair of prospects in a deal that was primarily considered a win-win, as López and Arraez both made their first All-Star team last season.

This deal would make Arraez the second multi-time batting champ to be traded midseason the year after winning an additional title, joining Lefty O’Doul (1933).

Arraez’s bat-to-ball skills are second to none. Since he debuted in 2019, he has recorded MLB’s only three seasons in which a player took at least 500 swings and had a whiff rate lower than eight percent. That fits right in with the Padres’ “get ‘em on and get ‘em in” philosophy, mixing on-base skills with slug. Their 21 home runs with men on base this season are tied for first in the NL with the Phillies and trail only the Yankees’ 22.

“You’re always looking for more offense and to maintain a better balance in the lineup,” said Padres manager Mike Shildt.

Adding Arraez would give the Padres another bat who could play multiple positions. Since joining the Marlins, he’s played primarily at second base but has 85 career games at first base, 79 at third and 48 in left field, though he hasn’t played out of the infield since 2021.

He’d almost certainly play every day with the Padres, likely in various positions. He could be the primary DH and shift to the infield whenever the Padres give Machado, Bogaerts or Cronenworth a DH day.

That would cut into Tyler Wade’s playing time, who entered Friday slashing .230/.329/.575. Wade has gotten 23 starts at third base when Machado slots in at DH, which was the case in the series opener at Chase Field.

Graham Pauley has also gotten eight starts this season, four at third and four at DH, but he’s looked overmatched at times. Adding Arraez could make him the odd man out to make room on the 26-man roster.
