Looks like the M's are rolling the dice on former Pirates first-rounder Sammy Siani. After struggling to live up to his high school hype in Pittsburgh, Siani's now got a shot to reset in Seattle. The outfield is crowded, but with Randy Arozarena possibly moving on after this season, could Siani break out and finally make his mark? Mariners fans, what do you think—hidden gem or just another flyer? #Sports #Baseball #Mariners
