* Mariners closer David Aardsma injured his back recently while “scrunched up reading a book” on the team flight to Florida. Seriously. No word yet on what he was reading, but presumably it wasn’t this book. * David Ortiz smacked his 25th homer last night while driving in four runs, and is now hitting .261/.356/.548 with 24 homers, 18 doubles, and 67 RBIs in his last 90 games after batting .187 with one homer through June 1. “I knew that when I got my swing back, good things were going to happen,” Ortiz said. * Giants manager Bruce Bochy inexplicably continues to give Eli Whiteside starts behind the plate when Bengie Molina needs a day off. Not only is Whiteside a career minor leaguer hitting just .200 in 45 games, the Giants have arguably the best catching prospect in baseball sitting on the bench. * Aroldis Chapman is going to become a very rich man once he’s officially declared a free agent, but for the most part Cuban pitchers haven’t had a ton of success in the majors during the past couple decades.
