"I'm here to make everyone else better, and be consistent. That's where I want to be in my career. ... If I can make the team better and everyone else in the bullpen better, that's what I'm going to do."
Lyon, 33, was 4-2 with a 3.10 ERA with the Astros and Blue Jays in 2012, striking out 63 batters in 61 innings.
He has recorded 79 saves in his 11-year career with the Jays, Astros, Tigers, Diamondbacks and Red Sox, although he last recorded double-digit saves in 2010 with the Astros.
It remains to be seen what happens with Lyon's role. But he is a very good pitcher and he makes the bullpen a lot deeper, at least on paper.
Terry Collins has said as recently as this week Francisco is the closer, but he is clearly concerned about Francisco's health and is not completely sold on his ability to be a stable force for the ninth inning. Lyon gives Terry that flexibility to make a change if necessary, and he also provides a safety net in the event Francisco suffers a setback with his elbow, which has been a problem since last September.
