Although Collin McHugh claims the longest undefeated streak in the majors, there's a bit of a blurred line when he faces the NL. The Houston right-hander also happens to be tied for the longest active winless streak against the Senior Circuit, and both streaks will be in play Tuesday night as the Astros welcome the San Francisco Giants for a two-game set. McHugh (4-0, 3.23 ERA) is 11-0 with a 2.31 ERA in 16 starts since the beginning of August, and another win would tie him with Wade Miller (2002) and Mark Portugal (1993) for the franchise record of 12 straight decisions won. The run includes two starts against the NL in which he didn't have a decision, and his last loss came against Miami on July 27.
