Those were two huge moves the club wanted to make to bolster the bullpen. It's the second consecutive year the Astros focused on relief pitching at the Winter Meetings, and after acquiring Luke Gregerson and Pat Neshek a year ago, Giles will fortify the back end and give Houston some needed firepower.
Giles is likely to become the Astros' closer, a role he held for the Phillies last season. He had a 1.80 ERA and 15 saves in 17 opportunities, averaging 96.5 mph with his fastball and striking out 87 batters in 70 innings.
Sipp, who had a 1.99 ERA last year, is valuable because he proved he could get out right-handers and left-handers and saw his role increase beyond a lefty specialist. And with the bevy of talented left-handed bats the Astros face in the division, they needed him back.
Both deals are pending physicals and could be announced by the end of the week.
The Astros reached an agreement to acquire Giles and reached an agreement to re-sign Sipp.
The Astros didn't lose any players in the Rule 5 Draft, which was somewhat of a surprise. The only player they selected was Mexican right-hander Octavio Acosta from the Mets in the Triple-A phase.
The Astros' biggest goal was met: relief pitching. Getting a closer who's under control for five more years in Giles and re-signing Sipp further fortifies a bullpen that was already a strength.
The club would still like to add a starting pitcher to the middle of the rotation. That could be easier to do via trade because of the high price tag in free agency, but the Astros have dealt away a lot of prospects in the last few months.
