His FIP is sitting in 2.36, and his opponents have a BABIP of.194 against him, so while he has been amazing he has not been quite as good as his ERA would suggest. His /9's are fantastic as well (4.4 H/9, 0.5 HR/9, 2.1 BB/9, 10.7 K/9), and he very much deserved his Player of MLB The Show 21 Stubs the Month card, submitting a 0.00 ERA at 11 2/3 innings in July, together with 5 hits, 3 walks, along with 16 strikeouts.
Rivero deserves a big time boost to his H/9, but I wouldn't vouch for a top 90 quite yet because of his.194 BABIP against. Since Dellin Betances includes a 4.7 H/9 and a 99 H/9, and the lowest H/9 Aroldis Chapman has posted in the last 3 years is 5.0 H/9 but he has a H/9 of 99, Felipe's 4.4 H/9 merits a increase from 86 to the low 90's, perhaps 92 or 93. Also, Rivero's BB/9 of 2.14 places him 22nd out of 162 qualified relievers, which positions ahead of Koji Uehara (79 BB/9), Andrew Miller (77 BB/9), Seung Hwan Oh (70 BB/9), and Joakim Soria (70 BB/9). His BB/9 of 62 deserves a boost into at least the 70's, if not more eventually. His HR/9 also deserves a bit of a boost.
The major worry I have with Felipe would be the outcome signal of investing in him. As there is a better POTM edition of him available at an inexpensive cost on the ticket counter, I am not sure how expensive his card could be if he went diamond. Personally, I wouldn't think it would go over around 10,000 stubs, and even that's a little bit generous. Additionally, there have been a few instances in the past where POTM picks had their LS updates slightly delayed, so while I'd think that Felipe would potentially go diamond if he keeps this pace, I am not quite confident enough to record him in the upgrades column.
First off, this card is a great budget reliever who I utilized until just yesterday as my seventh reliever. Wilson has had a very nice year, setting up a 2.76 ERA and a 1.016 WHIP. His BABIP against is a very modest.227 along with his FIP sits in 3.22, so he's gotten a bit lucky in the ERA section, but is getting a quality season nonetheless. Back in 10 2/3 innings pitched in July, he gave up 3 ER despite only allowing 4 hits, likely due to buy MLB 21 the show stubs his 4 walks also conceded. In addition, he struck out 11, and competitions only batted.118 against him. However, his HR/9 is also in a career high, and he's walking batters in a higher rate than the past two seasons.
