These are the top 10 pitching staffs in MLB as we enter play on Wednesday, July 30th.
1. Texas Rangers

Eovaldi and deGrom have been excellent so far for the Rangers, and their bullpen is much improved over the past few weeks.
2. New York Mets

Until recently, the Mets had the best pitching staff in MLB, but they have struggled lately and they have fallen in the rankings.
3. Houston Astros

The Astros have a top 5 team ERA and BAA this season. Hunter Brown has become the ace of the staff, but Valdez is still an ace as well, and Josh Hader remains one of the best closers in the game.
4. Kansas City Royals

The Royals rotation has picked up right where it left off a season ago, except for one big difference. Kris Bubic has become a legitimate weapon now, too.
5. San Francisco Giants

The Giants have gotten great pitching from Webb and Ray who are both NL Cy Young award candidates, and their bullpen has been sharp as well.
6. San Diego Padres

Led by staff ace Michael King and closer Robert Suarez, the Padres are one of the best staffs in the league.
7. Philadelphia Philles

The Phillies rotation is one of the best in baseball, but because their bullpen has been inconsistent, it has affected their overall numbers.
8. Seattle Mariners

The Mariners have great starting pitching now that they are healthy, and their bullpen is also one of the best. Their closer Andres Munoz has been a top 3 RP all season.
9 Boston Red Sox

The Red Sox rotation has been sub par aside from Garrett Crochet, but their bullpen has been excellent, anchored by Aroldis Chapman and it hasl led to them having a top 10 ERA.
10. Detroit Tigers

Mize and Skubal have been very good, Flaherty has been up and down but is mostly reliable, and the Tigers bullpen has been terrific for most of the season.
