Friday night (October 21st) kicks off this weekend’s boxing calendar, and several betting lines are appearing at sportsbooks for international fights, including Several Bookmakers. Check back later in the week to see if additional lines or over/under betting opens up. The Sleeman Sports Complex in Chandler, Australia hosts welterweight 12-round action as champion Jeff Horn (14-0-1) faces off against Rico Mueller (20-1-1) for the IBF Intercontinental title belt. Horn is nicknamed “The Hornet” and represented Australia at the 2012 London Olympic games, entering the pro ranks with a lot of national interest in his career. He has been on a fast track, winning multiple regional belts as his career progressed, and this fight against Mueller sees him making the fourth defense of his IBF Intercontinental belt. Horn is a massive -2000 favorite (bet $2,000 to win $100) over Mueller, who is returning at +1100 (bet $100 to win $1,100). The German Mueller is 1-1 in fights outside of his home country, and Australia is obviously a completely different trip than to Poland or Luxembourg, where his other fights took place. Nevertheless, Mueller is riding an impressive 11-fight winning streak. The Meadowbank Sports Centre in Edinburgh, Scotland will also host flyweight action, as popular Andrew Selby (5-0) returns to take on Hermogenes Elizabeth Castillo (11-0) of Nicaragua. Selby is the popular brother of IBF world featherweight champion Lee Selby, and Andrew has joined the pro ranks after an extensive amateur career that included a run of 9-1 in the “World Series of Boxing” promotions. Castillo is a 21-year-old adding valuable experience here early in his career, but he has never fought in anything but four- and six-round bouts until this one. Selby enters a prohibitive favorite at -4000 while Castillo is returning at +1600. A Super Lightweight 12-rounder between Dave Ryan (17-9) and Josh Taylor (6-0) for the vacant Commonwealth title at 140 pounds will take place there as well and has a more competitive line. Taylor’s long amateur pedigree still sees the 25-year-old heavily favored in this one at -650. Ryan, the +475 underdog, is returning to compete after a layoff of more than a year, and we last saw him losing the Commonwealth and WBC International titles to John Wayne Hibbert in September of 2015 via 10th-round TKO. Prior to that, he had stopped Hibbert in the nine round back in May of 2015 to win the titles.
