Robberies and close fights are two different things. This was a close fight, Zab did more in the early rounds most of Lucas punches didn't connect until late in the fight. Zab won close 114-113, no robbery.
Just watched the fight again and again had Matthysse win. Zab didn't do anything all night. He was hitting Matthysse with ineffective powerless jab, but as far as the most effective punches - Matthysse was killing him to the body. Matthysse just kept going to the body and had Zab busted and dropped Zab, and beat him convincingly in that round, and the next round and the next round. Matthysse was way more busier and landing body shot after body shot to Zab's one jab. Matthysse landed more counters than Zab.
