7-8-9? In the second inning?
1st game after an opener, he faced 9-1-2 (got all out), and the next inning 3-4-5-6 and let up one ground ball single.
Game 2 after an opener: he faced the 5-6-7-8-9-1 batters and did struggle but did get the #1 batter out to end the inning with just 1 run allowed.
Game 3 (after getting a GS in between) Here he did face the 7-8-9 and a CS helped him not face the #1 batter, He did struggle the next inning with the 1>6 batters, but allowed no runs.
Game 4: Samaniego faced 9 batters in the first, so Bello started the second inning vs the 1-2-3 batters. He let up 1 single, got a K and two groundouts. This allows me to say, "Yes, I'm sure."
Yes, as a SP'er his 1.357 OPS Against in the first inning could be related to facing the 1-2-3-4 batters, but he obviously did better vs those 1-2-3-4 batters over the full game than the first inning, so that kind of deflates the "against good batters" argument.
.708 v 1 slot
1.037 v 2 slot (better than 1.357)
1.071 v 3 slot (better as well)
.715 v 4 slot
The fact is, he started off way more slowly when starting the first inning rather than the second inning, and it was not related to facing the 7-8-9 batters in the second, as the batting slots seemed about equal between the two sample sizes.
