Outfielder Michael Siani was just designated for assignment by the Yankees and is available on waivers for the fourth time this winter. The Houston Astros could ruin the Yankees' chances of outrighting Siani to their Triple-A affiliate and bolster their outfield defense at the same time. After being DFA'd by the St. Louis Cardinals at the outset of the MLB offseason, Siani landed with the Atlanta Braves. Ironically, former Astros reliever Kaleb Ort was DFA'd by New York to make for Siani. Astro should take a flier on outfielder Michael Siani after Yankees DFASiani is a terrific defender.
