MLB Games and Probabilities for Friday

Let's look at the board, because I'm placing these trades right alongside you. If you want to play it safe and trade your $10 on the biggest favorite of the day—the Philadelphia Phillies on the moneyline at -211—you're looking at a modest profit of $4.74. But if you're like me and love chasing a bigger payout, placing that $10 trade on a heavy underdog like the Toronto Blue Jays (+188) gives you a real chance at an $18.80 profit if they can pull off the road upset.

When we're handicapping the marquee ATL @ NYY matchup, it’s a classic battle of big bats versus elite arms. The Braves bring the heat at the plate with a .250 team batting average and a .421 slugging percentage. The Yankees are lagging a bit offensively, hitting just .231 with a .412 slugging percentage.

However, New York counters with a dominant pitching staff holding a 3.334 overall ERA and a tight 1.188 WHIP, slightly edging Atlanta's staff, which carries a 3.627 ERA. Depending on whether you value the Braves' sluggers or the Yankees' shut-down pitching, either side presents a compelling case for a moneyline trade.
