I think Wilson is going to be just fine. I think he's really good. And he'll be dominant and we'll forget all about this start. I also think his fastball is nasty, even if we haven't been able to pick up on it. As was said earlier, he has the highest whiff% of all lefties with his four-seam this year: http://www.baseballprospectus.com/pitchfx/leaderboards/index.php?hand=&reportType=pfx&prp=ALL&month=&year=2017&pitch=FA&ds=ws&lim=200 It was also 4th highest of all lefties last year: http://www.baseballprospectus.com/pitchfx/leaderboards/index.php?hand=&reportType=pfx&prp=ALL&month=&year=2016&pitch=FA&ds=ws&lim=200 11th highest of all lefties in 2015: http://www.baseballprospectus.com/pitchfx/leaderboards/index.php?hand=&reportType=pfx&prp=ALL&month=&year=2015&pitch=FA&ds=ws&lim=200 8th highest of all lefties in 2014: http://www.baseballprospectus.com/pitchfx/leaderboards/index.php?hand=&reportType=pfx&prp=ALL&month=&year=2014&pitch=FA&ds=ws&lim=200 So, yeah, it's always been pretty nasty. And I'm not so worried about his off-speed stuff. Looking at the two guys that are most similar to him: Sean Doolittle and Jake McGee, he seems like he's even better with his fastball than them. They all throw four-seam fastballs, like, 90% of the time. They're lefties. They have similar stuff on their fastballs. They are all good. But Wilson's fastball is better. For 2017: Wilson: 11.77 (inches) vertical movement, 5.5 horizontal movement, 96.6 mph avg. velocity McGee: 9.74 vertical, 6.39 horizontal, 95.55 velo Doolittle: 11.23 vertical, 4.08 horizontal, 94.99 velo It might be because his movement is coming vertically that we can't tell how nasty it is? This year he has the 3rd-most vertical movement on it: http://www.baseballprospectus.com/pitchfx/leaderboards/index.php?hand=&reportType=pfx&prp=ALL&month=&year=2017&pitch=FA&ds=vmov&lim=200 Of 349 pitchers with 120 inning pitched since the start of 2015, he has had the 7th-most vertical movement, the 57th-most horizontal movement, and the 37th-highest velocity: http://www.fangraphs.com/leaders.aspx?pos=all&stats=pit&lg=all&qual=120&type=12&season=2017&month=0&season1=2015&ind=0&team=0&rost=0&age=0&filter=&players=0 http://www.fangraphs.com/leaders.aspx?pos=all&stats=pit&lg=all&qual=150&type=11&season=2017&month=0&season1=2014&ind=0&team=0&rost=0&age=0&filter=&players=0&page=2_30 http://www.fangraphs.com/leaders.aspx?pos=all&stats=pit&lg=all&qual=120&type=10&season=2017&month=0&season1=2015&ind=0&team=0&rost=0&age=0&filter=&players=0&page=2_30 Of 384 pitchers that have thrown at least 500 pitches this year, his four-seam spin rate is 34th highest, too: https://baseballsavant.mlb.com/statcast_search?hfPT=FF%7C&hfAB=&hfBBT=&hfPR=&hfZ=&stadium=&hfBBL=&hfNewZones=&hfGT=R%7C&hfC=&hfSea=2017%7C&hfSit=&player_type=pitcher&hfOuts=&opponent=&pitcher_throws=&batter_stands=&hfSA=&game_date_gt=&game_date_lt=&team=&position=&hfRO=&home_road=&hfFlag=&metric_1=&hfInn=&min_pitches=500&min_results=0&group_by=name&sort_col=spin_rate&player_event_sort=h_launch_speed&sort_order=desc&min_abs=0#results It's definitely nasty.
