Meh. Wacha was supposed to start tonight and was scratched, so it's Seabold. And, as you say, Bello is likely to start Monday for the simple reason that Sale, Eovaldi, Whitlock, Wacha (newly on the IL), and Hill are on the DL.
On top of that, the Sox are in the middle of 17 games without a break during which they play the Rays and Yankees 7 times each.
Sale, who did not have a good game last night at the AAA level--thus his rampage in the locker room--will nevertheless start Tuesday in Tampa because the Sox are desperate for starters.
Winckowski is far and away the best of the rookie starters, and last night the Yankees blasted him for 6 freaking runs.
Meanwhile the Sox lineup continues its lethargy except for the brilliance of Devers. The defense also continues to suck (despite Story's brilliance and Bogey's consistency).
The much maligned bullpen has the Sox most recent win by pitching all 9 innings. In the game before that, they pitched 7 innings, giving up 1 run, in another win.
In the now 3 straight losses to the Rays and Yankees, the starters, including Pivetta have all stunk.
So, thank you for expertise about Bello starting on Monday, but, frankly, I don't think it matters much. If Plawecki starts, now that would be news.
