Bullpen Heros for the Mariners

Since moving to the bullpen, Maurer has become a new pitcher. Posting ridiculous stats: 0.00 ERA 1.45 FIP 2.52 xFIP while striking out 31.6% of all batters he has faced. Things weren’t working out for him in the rotation, but moving to the bullpen has allowed him to use his two best pitches (fastball and change-up) and he has done an amazing job in his ten innings of work. Small sample size or not, anyone who watches the Mariners can tell you Brandon Maurer has looked infinitely better as a reliever.

Dominic Leone has been equally impressive this season. His 1.83 ERA isn’t a fluke either as he has posted a 2.73 FIP and 2.85 xFIP, so even if he regresses, it shouldn’t be so severe. He’s striking out 10.30 batters per nine innings and his groundball rate is at 51.5%, so he is a tough match-up with runners on base as well.

Dominic Leone freezes B.J. Upton with his slider.

 The Mariners are currently the second Wild Card team in the American League and their bullpen is a huge reason why that is the case. They lead all of MLB with a 2.39 bullpen ERA and given the injuries to James Paxton and Taijuan Walker (and Iwakuma early on), they’ve really stepped up to the challenge and kept the Mariners in the playoff race. While Chris Young continues to use smoke and mirrors to succeed (4.95 FIP & 5.38 xFIP) and rookie Roenis Elias begins to fade, the bullpen has stayed consistent. If Walker and Paxton can make any impact on the rotation with this bullpen in place… The Mariners could be a dangerous team come playoff time.

The Success of Scooter Gennett

 Why do people act like Scooter Gennett has come out of nowhere to play well?

He had a lot of minor league success: .297/.337/.371 .745 OPS and it's carried over to the majors: .317/.353/.481 .835 OPS. His numbers have been better in the majors, but he's been excelling in a platoon role with Rickie Weeks. He essentially kills right handed pitching, but struggles with lefties: .349/.386/.540 vs .143/.167/.324 against lefties. This is also allowing Rickie Weeks to bat primarily against lefties and he's doing a pretty solid job in that role: .262/.347/.464 which is good for an OPS of .812. If you've followed the Brewers over the past few seasons, you'll know that Weeks was entering Dan Uggla territory in terms of production, so this platoon allows the Brewers to get the best out of Gennett and Weeks.

Some of the success Gennett is having can be attributed to pure luck and his .389 BABIP against RHP would make that very obvious, but he's been producing at this level for nearly two seasons. One final stat of notice to me, his total percentage of contact made when swinging at all pitches is at 85.1% and that ranks higher than Miguel Cabrera 81.3% and Mike Trout 81.0% for the 2014 season. For reference, Jose Altuve is even higher than Gennett at 90.8%... Maybe it's just a short player thing? *Yep, just checked Pedroia and he's been around 89-90% for his career.*

So, Gennett may be the product of a successful platoon, but there's no denying that he's a great contact hitter. To me, he's right in line with guys like Jose Altuve and maybe even in the same realm as Dustin Pedroia. Altuve may have more speed and Pedroia might have better power numbers, but Gennett is right with them both in terms of their contact rates. I've seen some other writers claiming they've been "wrong" about Gennett and while I think he's doing a great job, his splits do point towards his success being because of his platoon role. I would like to see him get a chance everyday soon, but why break up a good thing between him and Weeks? In the meantime, the Brewers keep on winning and Gennett keeps on hitting.
