Patrick Beverley is warning Los Angeles Lakers rookie guard Lonzo Ball of a rude awakening in the NBA.

The newly acquired L.A. Clippers guard, known as one of the peskiest defenders in the NBA, has circled Oct. 19 on his calendar, the day he’ll get to get chance hounding the much-ballyhooed former UCLA Bruin playmaker, who’s already garnering tons of praises despite not having played a single NBA regular season game yet.

Ball couldn’t have asked for a more difficult matchup in his NBA debut, as Beverley’s no-nonsense approach on defense will give the second-overall pick of this year’s draft all he could handle. Beverley, sent in a package of players to the Clippers by the Houston Rockets this offseason in exchange for Chris Paul, was named to the 2017 NBA All-Defensive First Team and was also part of the 2014 NBA All-Defensive Second Team.

The five-year NBA veteran has career averages of 9.3 points, 3.4 rebounds, 4.1 assists, and 1.3 steals in his career. His 1.5 steals per contest last season was a career high.
