Tennis betting picks: Best 2023 US Open qualifying bets for Friday from tennis expert

The 2023 US Open qualifying matches continue on Friday as players try to punch their ticket into the main draw of the 2023 US Open next week. There will be a mix of semifinals and finals on Friday, as some of Thursday's semifinal matches were unable to be played due to rain. Former World No. 5 Kevin Anderson, who was a finalist at the 2017 US Open, is among the players in action on Friday. 

Before you make any tennis picks for the US Open qualifying matches, you need to see who tennis expert Blake Von Hagen is backing.
