So Marco Estrada was one of my preseason sleepers/undervalued/targets/whatever this year. I suspect a lot of other users shared that view, and were disappointed with him this year. I, luckily, didn't draft him, taking Jeter in the 10th round instead in my keeper league. (What?! Jeter in the 10th? Followed by Ichiro and Marcum in the 11th and 12th round? What the hell? How am I winning my league? I love looking back at my draft as the season draws to a close. Ahem, I digress. Back on topic.)
Right now Estrada is only owned in 23% of Yahoo leagues. Have you seen what he's done since returning from the DL? 24 IP, 21 K, 1.88 ERA, 0.71 WHIP. Not too shabby. If he was on your radar as a cheap yet effective innings filler, might be worth checking on his availability in your league. Definitely worth a flyer in H2H. Not sure I completely trust him yet in my roto league (1450 IP limit), but I'm stashing him in case Fernandez, Wheeler and/or Teheran get shut down and I need to fill in those innings.
