Each day, the MLB Immaculate Grid publishes a challenge for baseball fans young and old. Administered by Baseball Reference, the puzzle has quickly become a favorite.
Users are presented with a 3x3 grid with clues scattered across both the x-axis and y-axis. At the intersecting square, users must enter the name of a player who has appeared for both teams at some point in their career. Sometimes, the team criteria is replaced by a career achievement or milestone.
On Aug. 3, among other puzzles, the Immaculate Grid required users to name players who have suited up for both the Boston Red Sox and the San Francisco Giants at some point in their career. Today, we are going to take a look at some of the eligible names.

A longtime infielder, Venezuelan Marco Scutaro came to the San Francisco Giants at exactly the right time. Acquired by the team at the 2012 trade deadline, he was an instrumental part of the team's World Series win that year, and even delivered the series-clinching RBI in Game 4 to complete the sweep, leading to a three-year, $20 million extension.
Scutaro played for the Red Sox in 2010 and 2011, hitting 18 home runs and 110 RBIs over the course of 1,027 at-bats.

Current San Diego Padres manager Bob Melvin also played for both teams. Melvin, a 1979 third-round pick of the Orioles, joined the Giants in 1986, his sophomore season. Melvin's best year in terms of power came in 1987, when he hit 11 home runs and 34 RBIs. However, the catcher only managed to hit .199. He joined the Red Sox in 1993 before retiring a year later.
2013 Giants first-rounder Christian Arroyo is another possible answer for today's Immaculate Grid. In 34 games in 2017, his rookie season, Arroyo hit just .192/.244/.304. After stints in Tampa Bay and Cleveland, Arroyo was traded to the Boston Red Sox in 2020, where he remained a part-time member. A .241 hitter, fans are still waiting for Arroyo's bat to come alive.

Older fans will remember outfielder Ellis Burks. Burks made his debut for the Red Sox in 1987. Three seasons later, the Virginia native hit 21 home runs, 89 RBIs and stole nine bases to be named a Silver Slugger, as well as a Gold Glover.
A two-time All-Star in Boston, Burks played 42 games for the 1998 Giants alongside Barry Bonds after being traded to the team by the Colorado Rockies earlier that season.
