Lefties could solidify Astros’ formidable roster

When Astros general manager Jeff Luhnow signed free-agent relievers Joe Smith and Hector Rondon, both right-handers, last week, he made it clear he could take this roster to Spring Training and feel good. If he could add a lefty reliever to his bullpen, he’d feel even better. If he hasn’t already tried to re-engage the Padres about Brad Hand, he will a time or two before the start of Spring Training.
