ST. LOUIS (AP) -- Devon Alexander, in his first fight in the 147-pound division, used the added weight to record a unanimous 10-round decision over Marcos Maidana on Saturday night.
Alexander, a St. Louis native and former WBC and IBF junior welterweight champion, improved to 23-1. Maidana, who hails from Argentina, fell to 31-3 in his welterweight debut.
The 25-year-old Alexander dominated the non-title bout, capturing nine of 10 rounds on two judges' cards. He finished with advantages of 100-90 100-90, 99-91.
Alexander, a 2-1 favorite, recorded a second straight win after his lone loss -- a 10-round setback against Timothy Bradley on Jan. 29, 2011, that cost Alexander his belts.
