Sophomore Year 2016: National League edition

We are coming off a season in which Major League Baseball’s wealth of first-year talent was on display. In fact, there is a trend beyond the aptly titled “Year of the Rookie” of youth contribution to big league squads. Prospect Insider’s Jason A. Churchill looked at this in more depth when he examined the American League West’s pre-arbitration players to better assess the division’s future. These players have played an increasingly important role on successful teams. Here, we’re going to take the performances of some of the National League’s top rookies and examine what…

Preview Capsules: Catchers

Chris Iannetta 2015: 92 G, .188/.293/.335, .225 BABIP, .281 wOBA, 80 wRC+, 1.4 fWAR Iannetta, 32, fell of the map at the plate last season, but maintained his sound defense while fighting some minor, nagging injuries. The Mariners are hoping he’ll bounce back, and despite 6774 innings behind the plate, that triple-slash is headed north in 2016. The question is: how far back does he get? It’s reasonable to expect what STEAMER does — .215/.323/.353 — and probably not much more, though Iannetta’s career marks sit at .231/.351/.405. The innings…

Preview Capsules: Bullpen

Steve Cishek, RHP: 4FB, SNK, SL, CH 2015: 59 G, 55.1 IP, 7.81 K/9, 4.39 BB/9, 46.1% GB, .313 BABIP, 3.86 FIP, 0.0 fWAR Cishek was dominant two straight years as the Miami Marlins closer 2013-14, missing bats and limiting bases on balls to let his stuff take over high-leverage innings. None of the above occurred in 2015, with the 29-year-old taking a step back in performance, but perhaps most importantly all the areas that led to those two top-flight seasons. The velocity was down a full tick from 91.7…

Preview Capsules: Starting Rotation

Felix Hernandez, RHP: 4FB, SNK, CB, CH, SL 2015: 31 GS, 201.2 IP, 8.52 K/9, 2.59 BB/9, 56.2% GB, .288 BABIP, 3.72 FIP, 2.8 fWAR Felix Hernandez had his worst season in eight years in 2015, but still was very solid at the top of the Seattle Mariners’ rotation and despite the buzz about the 2,200 innings under his belt in his 10-plus seasons, the ace still averaged 92.1 mph on his fastball and his issues last season don’t appear to have been physical in nature. All this suggests 2015…

Better assessing the future of the AL West

There are many ‘Under 25′ or ’25 and Under’ player rankings to go along with the farm system rankings put out by Keith Law, MLB.com and Baseball America. A good number of the sites covering prospects offer such a ’25 and Under’ type list, apparently in attempt to better evaluate where each club is in terms of young talent. Not Prospect Insider. Why? I’ll explain. For starters, the age of 25, or any other age one might choose as the cut-off, is 100 percent arbitrary. Why not 27? Why not…

Best Tools, Fast Risers, Hot Seat M’s Prospects

The Seattle Mariners’ farm system is thin, especially at the top, but it doesn’t lack for legitimate tools, particularly in the field and at the plate. The club’s 2015 Draft class provides some help, but a couple of mid-season deals made by the previous regime contributed to this list, too. Best Tools Fastball Starter: Luiz Gohara Has been up to 97 mph, typically sitting 92-95. In 2015, many outings showed 90-94. Will need to show better in all other areas for it to matter, anyway, but the firmer version is…

Mastering the JeDi code

From what I’ve been able to determine, social media bestowed Seattle Mariners general manager Jerry Dipoto with the nickname of “JeDi” while he was still working for the Los Angeles Angels. I wasn’t aware of this clever nod to the fictional characters in the “Star Wars” movie franchise until I noticed it on Twitter after his Seattle arrival. I have to admit that it did make me chuckle a bit. [pullquote]The lineup needs to be a little bit longer. The rotation needs to be a little bit deeper. The bullpen…
