Wheeler is the top-ranked baseball recruit in the state of Arizona according to ESPNHS. As a junior at Phoenix Thunderbird High School last year, Wheeler earned Black Canyon Region Player of the Year honors, batting .554 with 16 doubles, 10 homers and 50 RBIs. He helped the Chiefs to a 27-4 overall record last season and a runner-up finish in the Arizona 4A Division II State championship. Wheeler has also excelled on the basketball court, manning the point for Thunderbird's basketball team the last two seasons.
"Marcus is a very advanced hitter. What stood out in the evaluation period was his approach and discipline at the plate, as well as his ability to drive the baseball using the whole field. You don't see that very often from players his age with plus power. Marcus is a power-hitting corner infielder who has good actions defensively. We believe that once Marcus finishes his successful high school basketball career and focuses solely on baseball, he is only going to get better and has a chance to be an impact guy in the middle of our lineup," Ritchie Price said.
