From Pete Abe:
Mariano Rivera since July 1: 18.2 innings, 19 hits, 7 earned runs, 2 walks, 22 strikeouts, 2 home runs. That’s a 3.38 ERA.
Obviously for Rivera those aren’t great numbers (and for some reason 6 of those runs came in non-save situations). But overall, the 21 base runners in just under 19 innings is still pretty good. That 7 of those base runners scored is probably a combination of bad luck and those 2 HRs. Part of what has made Rivera so good over the years is how tough it is to hit a homerun off of him. I only saw the Delmon Young homerun live, and to me it showed a bit of a pattern: right handed hitter with a quick bat who swings at a lot of pitches leans out over the plate at that cutter away. Guys like Vernon Wells and Jose Guillen have been able to do it too over the years.
So what does all this mean? That Mo is fine – even the best ever is going to go through a rough patch. Just think – a 3.38 ERA and it’s considered a slump.
