There’s a big gulf between those two, but for what it’s worth:
The motives behind trading these guys differ, of course. Trading Porcello gets you talent for an MLB-regular starting pitcher, with the Tigers likely believing that Porcello’s production can be matched or exceeded my making Drew Smyly a regular. With Scherzer you have the “plug in Smyly” option there of course, but it’s way more about getting peak value and return in a trade of a starter while avoiding having to think about an extension.
There’s no such thing as having too much pitching. But when you have a lot of starting pitching like the Tigers do, you at least have options.
You can’t pick your family and no one knows that better than Giants shortstop Brandon Crawford. His sister Amy married Astros starter Gerrit Cole in November 2016, so the two players are brothers-in-law.
The two players have matched up against each other 18 times in the past, as Cole spent his first five seasons in the National League with the Pirates. Cole often won that battle, holding Crawford to four hits — all singles — in 18 plate appearances.
Crawford finally got the better of Cole on Tuesday night, hitting a line drive into the appropriately-named Crawford Boxes at Minute Maid Park for a two-run home run, cutting the Astros’ lead to 5-2.
