Aroldis Chapman struck out the side for a perfect ninth inning against the Cubs and picked up his 19th save on Wednesday.
Chapman has been a great fantasy asset up to this point, owning a 2.36 ERA and 0.83 WHIP through 26.2 innings while converting 19 of his first 21 save opportunities. There were many questions as to whether or not he would be able to perform at a high level following a terrible head injury, but his 52:9 K:BB rate certainly suggest he is just fine.

Miguel Castro will open the season in the majors.
Castro flew under the radar in the minors last season, but is making the rare jump from A-Ball to the majors. This is thanks to his (likely) temporary move to the bullpen for the Spring, which enabled his stuff to tick up a bit in shorter outings. He's likely next in line to receive saves should Brett Cecil fail, and the 20-year old is worth keeping an eye on. Analysis: Ben Diamond
