Luis Arraez Traded to Phillies, Latest on Giants' Return and Philly's Updated Lineup

The Philadelphia Phillies acquired second baseman Luis Arráez and right-handed pitcher Caleb Kilian from the San Francisco Giants in exchange for right-handed pitchers Ramon Marquez and Marty Gair.

ESPN's Jeff Passan first reported the deal.

The 29-year-old Kilian is a right-handed reliever who made 45 appearances for the Giants this season (4.26 ERA, 53 strikeouts).

Marquez, 20, is a right-handed pitcher and was the fourth-ranked prospect in the Phillies' farm system. The 23-year-old Gair is a right-handed reliever currently playing in Single-A.

Todd Zolecki of MLB.com broke down what the Phillies' defensive alignment will look like. Of note, Bryce Harper is expected to move from first base to the outfield.

With that in mind, here's a look at the Phillies' potential lineup, per Roster Resource.

1. SS Trea Turner
2. DH Kyle Schwarber
3. RF Bryce Harper
4. 2B Luis Arráez
5. 1B Alec Bohm
6. LF Brandon Marsh
7. 3B Bryson Stott
8. C J.T. Realmuto
9. CF Justin Crawford

The Athletic's Matt Gelb, Andrew Baggarly and Charlotte Varnes also provided potential options the team could explore after talking to sources:

• Arraez plays second base, Harper plays right field, Stott plays third base and Bohm plays first base
• Arraez plays second base, Harper stays at first base, Stott moves to third base and Bohm could be traded
• Arraez plays second base, Harper stays at first base, Bohm stays at third base and Stott moves to the outfield

Joel Sherman of the New York Post provided his take as well.

Arráez, 29, is in his eighth MLB season. He has played for the Minnesota Twins, Miami Marlins, San Diego Padres and Giants. Arráez is a four-time All-Star, three-time batting champion and two-time Silver Slugger. He is MLB's current active leader in batting average.

For the season, Arráez is hitting an MLB-best .324 (.801 OPS) with four home runs and 43 RBI. He made his fourth All-Star Game this season. Arráez was San Francisco's only position player on the All-Star roster (Giants starting pitcher Logan Webb also made the game).

Arráez finalized a one-year, $12 million contract with the Giants last February. He's certainly helped the club this year. Overall, though, it's been a nightmarish year for the 47-65 Giants, who sit fourth in the National League West.

At this juncture, making the playoffs is near-impossible. The Giants obviously wanted to avoid losing Arráez, an impending free agent, for nothing this offseason, so trading him makes sense.

Ken Rosenthal of The Athletic put the idea of the Giants being sellers out there in a June 15 piece.

"The San Francisco Giants have not fully committed to becoming sellers at the trade deadline. But they are moving closer to making that determination.

"In recent days, the Giants have put out feelers on some of their players, testing the waters for potential deals, according to people briefed on their discussions."

Rosenthal added that "the most obvious players for the Giants to move" would be Arráez and left-handed starting pitcher Robbie Ray, another impending free agent.

On July 6, Passan listed a host of MLB trade candidates, and he predicted that there was a 90 percent chance Arráez would be dealt by the Aug. 3 deadline.

Arráez was asked about the potential of him being moved at midseason. He understood the business of baseball but also acknowledged his strong desire to play second base at his new home (h/t Mark Feinsand of MLB.com).

"This is a business, so whatever team wants to give me the opportunity to help, it's going to be at second base," Arráez said. "I don't like to go back to first base; I prepared my mind, I prepared my body to only play second base.

"One hundred percent, I'm staying at second."

That appears to be the case in Philadelphia as it hopes to make the playoffs and perhaps a late run at the NL East crown. Currently, the Atlanta Braves lead the second-place Phillies by eight games. Philadelphia is also tied for the second wild card spot with the Arizona Diamondbacks.

As for San Francisco, the Giants look toward the future and hope for brighter days.
