Errol Spence (21-0, 18 K) stopped Leonard Bundu (33-2-2, 12 KO) with one minute left in round six. Bundu was so hurt that he did not attempt to make the ten count as he laid on his back in an awkward position that could have resulted in injury to his knee.
The takeaway is not Spence’s prowess as a puncher, for Keith Thurman was able to knock Bundu down on one punch himself. Rather, Spence was able to use his outboxing to completely control Bundu before taking him out. This is relevant in the consideration of Thurman only insofar as Spence demonstrated that he could possibly use the same tactics to win a decision over Thurman. For Thurman is the smaller of the two and would have to figure out a way to get inside on Spence.
Bundu was determined to win as he was aggressive from the beginning. (Chris Algieri, normally an outboxer, took the same general approach of trying to back up Spence. His trainer, John David Jackson, who also trains Sergey Kovalev, is known for encouraging his fighters to be aggressive. So it is unclear whether Algieri did this because of ideology or a scouting report.)
Spence began as he ended, using the right jab frequently, to freeze Bundu, as he followed it with an assortment of left hand striking – straight left hands to and body, left hooks to head and body, left uppercut to head and body. In effect, Spence’s left hand was six different punches.
Bundu continued to move forward but without throwing many punches due to Spence’s constant activity and long reach.
Bundu occasionally landed a hook with either hand as he switched frequently and the angle of his punches were unpredictable. Spence was defensively responsible nevertheless.
Unsuccessful trying to lead, Bundu then resorted to countering and catch-and-shoot tactics, hoping to catch Spence wide open after throwing a punch. That lasted for about thirty seconds and all continued as before. Spence managed to knock out Bundu’s mouthpiece from an uppercut causing a time out. When time resumed Spence was noticeably more aggressive and punched with more intention.
Bundu attempted occasional flurries to the body. On the other hand, Spence never threw any combinations, once punch at a time with either hand at a consistent pace.
Spence started this round moving forward and throwing harder punches; he was certainly trying to hurt Bundu at this point. A left uppercut to the solar plexus floored Bundu and appeared to leave him gasping for air. Never able to recover and breathing heavily, Spence then knocked him down again at exactly one minute left from a right hook to the head. Bundu did not make an attempt to get up, for not only was he dazed, he was still winded.
Another point needs to be made regarding Keith Thurman, for Bundu-Spence is only relevant in the context of Thurman having already fought Bundu. Spence is taller and rangier than Thurman, which allowed him to have a seemingly easier time with Bundu. Thurman would have had to exchange more with Bundu to produce the same output as Spence. So again, Spence’s easy time with Bundu only suggests that he can use his range to outbox Thurman as well, nothing more.
