If I was to rank those from most concerned to least concerned....
Castro - Ignoring what the numbers are telling me, he just hasn't looked very good. The fact that the numbers back that up only adds to the concern. Concern meter at 7/10
SWR - I think most can agree that he punched a little above his weight last year. So, coming into 2025, I was completely on board with giving him a starting job, but also a bit skeptical of him being as effective as 2024. The skepticism seems to have been relatively warranted based on his first 1/4 of the season. His results have been slightly better (slightly lower ERA, slightly higher K rate), but the eye test and advanced numbers tell a different story. My concern is that he'll continue to give us average to below average results (5 IP. 2-3 runs allowed) and it'll block a higher upside option at AAA. Concern meter at 6/10
Hard Hit % - Not sure that an elevated HH% has translated to an elevated HR rate, but as the weather warms that might change a little. I think that's just kind of the type of pitching staff we have. Going to give up some hard hit balls, but if you limit the walks (Lowest in Baseball) and have a high strikeout rate (7th in baseball), then you'll mostly limit big damage. Add in the fact that the bullpen has a lot of depth and we have Festa and Matthews sitting in AAA if one of the pitchers really starts to give up big damage, I'm left largely unconcerned. Concern meter at 3/10
Varland - You're sort of double dipping here with the overall hard hit %. Varland specifically feels small sample-ey to me. Concern meter at 2/10
Bader - Love his defense. Love his attitude. His offense is a bonus. He can still be a valuable member of a playoff team batting 225. Concern meter at 1/10
