MLB Immaculate Grid is a baseball quiz that tests fans' knowledge every day. Despite being relatively new, fans of all ages have been flocking to the Baseball Reference game.
The 3 x 3 Immaculate Grid follows a simple concept. Using three clues lined up along the x-axis and another three on the y-axis, players must populate the relevant squares with the names of MLB players, present or past.
On Sept. 5, the Immaculate Grid required participants to name MLB players who have appeared for both the Philadelphia Phillies and the Oakland Athletics.

Let's take a look at some top names.

Center fielder Dwayne Murphy was a fixture of the Oakland Athletics in the 1980s. Between 1980 and 1985, Murphy won six straight Gold Gloves. He was known for hitting second in the lineup, after Hall of Famer Rickey Henderson.
Currently a hitting coach for the Texas Rangers, Murphy played 98 games for the 1989 Philadelphia Phillies, hitting nine home runs and 27 RBIs before announcing his retirement at the end of that season.

Utility man Josh Harrison began his career with the Pittsburgh Pirates. He began to gain attention in 2014, after hitting .315/.347/.490 with 13 home runs, 52 RBIs, and 18 stolen bases. A two-time All-Star during his time with the Pirates, Harrison was traded to the Oakland A's in 2021 in exchange for Yan Gomes. In 2023, he signed a deal with the Phillies, but was released after managing to hit just .204/.263/.291 with a pair of home runs in 41 games.
It was a long road to stardom for pitcher Dave Stewart. A native of Oakland, Stewart was selected in the 15th round of the 1975 draft by the Dodgers. He spent about seven years as a journeyman, playing for three teams including the Phillies.
In 1986, the 6-foot-2 right-hander joined the Oakland Athletics. During his second season with the team in 1987, Stewart posted an ERA of 3.68 to accompany an AL-best 20 wins to finish third in Cy Young voting that year.
One season later, Stewart led MLB in starts, complete games, innings pitched and batters faced to log a fourth-place finish in Cy Young voting. The 1989 World Series champ retired in 1995.

Current Detroit Tigers manager A.J. Hinch also played for both teams. A veteran manager who served a suspension for his role in the Astros sign-stealing scandal, Hinch was selected by the A's in the third round of the 1995 draft.
The best season of his career came in his rookie season of 1998, when he hit nine home runs and 35 RBIs in 120 games. His career in MLB was, however, short-lived. Hinch retired in 2004 after a very short stint with the Phillies.
