I'll be very surprised if Garcia is the only bullpen addition this offseason. Hopefully he's not the higher profile addition if more signings are to come.
His high leverage numbers are not great (4.37 FIP in 21.2 innings, but LOB is absurdly low at 36.3% so you would think his overall numbers should be bound to improve), medium leverage is actually worse (6.26 FIP in only 11.1 innings), and he excelled in low leverage situations (2.36 FIP in 24.2 innings). Hopefully he can improve his high leverage numbers, his contract suddenly doesn't look so good if he's pitching mostly in low leverage situations.
