Ain't that the truth! I had to lookup SIERA. From Baseball Prospectus: "Skill-Interactive Earned Run Average estimates ERA through walk rate, strikeout rate and ground ball rate, eliminating the effects of park, defense and luck." WHAT?? LOL!! Someone later in this threat brought up XBH: "also known as a long hit, is any base hit on which the batter is able to advance past first base without the benefit of a fielder either committing an error or opting to make a throw to retire another base runner (see fielder's choice)." Again: WHAT?? Just too many statistics now! I'm more of a 'see ball, hit ball' kinda guy. I believe in the theory of KISS. Yes, I'm probably older than most of you posting Sinkerball pitchers usually don't pitch that well coming out of Spring Training. Theory is: they're too strong. As the summer heats up and as a sinkerballer tires out a bit, they stop "overthrowing" a sinkerball really starts to sink. I expect better out of Gibson over the next few weeks.
