With a full 15 MLB games on today, every team will be in action. Let's look at the best player props to target this Friday, May 20.MLB Player Prop #1: Adam Wainwright Over 4.5 Strikeouts (+105)Pittsburgh Pirates vs. St. Louis Cardinals Match DetailsFixture: St. Louis Cardinals @ Pittsburgh PiratesDate & Time: Friday, May 20, 6:35 p.m. EDTVenue: PNC Park, Pittsburgh, PAOn Sunday, Adam Wainwright and Yadier Molina won their 203rd game as a battery, the most in MLB history. Wainwright threw six solid innings of two-run ball against the Giants to achieve the feat, which was his third consecutive quality start. The 40-year-old has been pitching well lately, lowering his ERA to 3.15 on the year. Even at this age, he's striking out 7.4 batters per nine innings, which is right around his career average. He'll be facing a Pirates team Friday that punches out at the seventh-highest rate in the MLB and one that holds the third-lowest OPS, meaning they're unlikely to have a lot of base runners in the series opener.
