As baseball action heats up, betting enthusiasts should mark their calendars for exciting matchups this week, notably when the Arizona Diamondbacks take on the Los Angeles Dodgers. Expert Mike Barner has delivered a stellar season record of 20-3, showcasing keen insight into player prop betting. For those looking to place informed wagers, Barner highlights key player prop bets for May 9.

In the matchup between the New York Yankees and Oakland Athletics, the bet on Osvaldo Bido to allow over 4.5 hits stands out. The Yankees, despite a couple of key injuries, have maintained a strong offensive presence. Additionally, Francisco Lindor's prop bets indicate potential for high performance against the Cubs' Jameson Taillon, particularly with Lindor's impressive home OPS.

Jackson Merrill, back after a hamstring injury, also presents intriguing value with a prop bet of over 0.5 RBI, especially facing a favorable pitcher in Antonio Senzatela at Coors Field. With several factors at play, these prop bets offer great opportunities for savvy bettors.

The New York Yankees are set to face off against the Oakland Athletics in a three-game series at the Sutter Health Park in Sacramento. This marks the Yankees' inaugural visit to the Athletics' temporary home as they transition from Oakland to Las Vegas. The matchup will showcase Yankees' superstar Aaron Judge, who's currently leading MLB with an impressive .400 batting average, 12 home runs, and 34 RBIs against the Athletics' Osvaldo Bido.

In their recent matchup against the San Diego Padres, Judge did experience a slight slump, batting 0-for-4 with three strikeouts, impacting his average slightly. Despite this, his season performance remains stellar. The Athletics, despite a slow start to the season, are expected to see a boost in attendance as the Yankees bring their fans to the game.
