Dinelson Lamet was excellent yesterday, striking out 14(!) against the Brewers in only 6 innings. This start single handedly moved him up draft boards next season. He's a fantastic sleeper with low-risk and high-upside as his K% is over 30%. His SIERA is hovering near 4.00, but that can be improved upon as he's just 26-years old. His arrow is pointing way up for next season.
Jon Lester was effective, but lasted just 5 innings in a No Decision while allowing 1 run with 5 strikeouts. Lester has been pretty consistent in the last two years; we should expect 160-185 innings with a 4.50 ERA. He did improve his K% this season, which is a positive. It will take some reinventing for him to be more fantasy relevant next season.
Buster Posey sat again yesterday, but will reportedly be available on Thursday. It's disappointing that he couldn't even start at DH playing in Boston, especially if you were hoping for a late season run for Posey. It's crazy to say but he shouldn't be drafted in 2020. The rest of the league has gotten better at hitting, while Posey has shown less power than a little leaguer. His decline has been extremely sudden, as he was a top catcher in 2017.
Christian Walker was 2-for-4 with a HR, his 26th of the season. While Walker has improved greatly from last year, he's sporting a wRC+ that's barely above league average. Walker is unlikely to provide significant fantasy value next season unless he can get comfortable at the MLB level. He has mashed AAA multiple times, but it hasn't translated to the big stage. He may be a sleeper for very very late in drafts, but that's being generous.
Noah Syndergaard went 5.2 while allowing 4 ER against the Rockies. He sports an unimpressive 4.22 ERA. Syndergaard regressed a bit in 2019, primarily because he's allowed significantly more home runs this season. He presents decent value in 2020 as I can see him returning to a mid-to-low 3 ERA area with some balls bouncing differently next season. Despite the lackluster year, don't be afraid investing in him.
